Connection
Before the closing tag
need to connect slidr.js or slidr.min.js file.
HTML markup
slidr.js can work with any inline, inline-block, block elements that have an id attribute. It is allowed to use any first-level child elements with the data-slidr attribute, for example:
apple
banana
coconut
apple
banana
coconut
Javascript
After connecting slidr.js the global slidr object will become available. The easiest way to create a slidr is:
The slidr global namespace provides the following functionality:
/ ** * Current version * @return (string) major.minor.patch. * / function version () (); / ** * Available transition effects. * @return (Array) of transitions. * / function transitions () (); / ** * Creates and returns Slidr. * Calling this function twice on the same element will return the already created Slidr object. * @param (string) element id for Slidr. * @param (Object =) opt_settings Slider settings. * / function create (id, opt_settings) ();
Slider API
// Initialize Slidr with custom settings var s = slidr.create ("slidr-api-demo", (breadcrumbs: true, overflow: true)); // Add horizontal slides with a standard transition effect. // duplicate array element "one" at the end lets Slidr // scroll the slides endlessly s.add ("h", ["one", "two", "three", "one"]); // Adds a vertical slide with a cube transition effect. s.add ("v", ["five", "four", "three", "five"], "cube"); // Launch the slider. s.start ();
The complete list of Slidr.js API functions is presented below.
/ ** * Start the Slidr! * Automatically finds slides to create if nothing was added prior to calling start (). * @param (string) opt_start `data-slidr` id to start on. * @return (this) * / function start (opt_start) (); / ** * Check whether we can slide. * @param (string) next a direction ("up", "down", "left", "right") or a `data-slidr` id. * @return (boolean) * / function canSlide (next) (); / ** * Slide! * @param (string) next a direction ("up", "down", "left", "right") or a `data-slidr` id. * @return (this) * / function slide (next) (); / ** * Adds a set of slides. * @param (string) direction `horizontal || h` or `vertical || v`. * @param (Array) ids A list of `data-slidr` id" s to add to Slidr. Slides must be direct children of the Slidr. * @param (string =) opt_transition The transition to apply between the slides, or uses the default. * @param (boolean =) opt_overwrite Whether to overwrite existing slide mappings / transitions if conflicts occur. * @return (this) * / function add (direction, ids, opt_transition, opt_overwrite) (); / ** * Automatically advance to the next slide after a certain timeout. Calls start () if not already called. * @param (int =) opt_msec The number of millis between each slide transition. Defaults to 5000 (5 seconds). * @param (string = ) opt_direction "up", "down", "left", or "right". Defaults to "right". * @param (string =) opt_start The `data-slidr` id to start at (only works if auto is called to start the Slidr). * @return (this) * / function auto (opt_msec, opt_direction, opt_start) (); / ** * Stop auto transition if it "s turned on. * @return (this) * / function stop () (); / ** * Set custom animation timings. * @param (string | Object) transition Either a transition name (i.e. "cube"), or a ("transition": "timing") object. * @param (string =) opt_timing The new animation timing (i.e "0.5s ease-in"). Not required if transition is an object. * @return (this) * / function timing (transition, opt_timing) (); / ** * Toggle breadcrumbs. * @return (this) * / function breadcrumbs () (); / ** * Toggle controls. * @param (string =) opt_scheme Toggle on / off if not present, else change layout. "border", `corner` or` none`. * @return (this) * / function controls (opt_scheme) ();
Scrolling the page while changing slides
This nasty bug appears in some browsers. To fix it, you need to add style to the body:
Body (overflow: hidden;)
Dynamic resizing
Slidr "understands" whether the slider needs to be resized to fit the image. If the slider block has dimensions specified, then Slidr will not automatically change them. If the min-width and min-height properties are specified, then the slider will resize to fit the content, taking these values into account. Otherwise, sizing will be performed automatically.
Automatic resizing

Slidr controls
The markup for the controls is as follows:
You can customize any slider control using CSS selectors:
The arrow control is implemented with the: after pseudo selector, so to hide it, use the following code:
// Hide a single arrow within a single controller. aside .slidr-control.right: after (border-color: transparent! important;) // Hide all arrows within a single controller. aside .slidr-control: after (border-color: transparent! important;) // Hide all Slidr arrows. aside .slidr-control: after (border-color: transparent! important;)
Slidr Breadcrumbs
Breadcrumbs have simple HTML markup. Each ul stands for an entire line, and each li stands for a separate breadcrumb:

From the author: Despite rumors about the alleged "death" of the part of web pages visible without scrolling, the need for a good slider has not disappeared anywhere. Let's be honest, just for a second - sliders are fun. In addition, nothing else, unlike moving content, causes a wow effect for the user. All sliders are a set of several slides that replace each other and it is extremely important that the slider code is as light as possible. This is where jQuery comes in handy.
Take a look at the 20 jQuery sliders from Envato Market and you'll see that there are sliders that are more than just a block of smoothly changing images.
1. RoyalSlider - Touchscreen image gallery on jQuery
A responsive slider that is also touch-friendly means a lot more now than it used to. RoyalSlider combines both responsiveness and touchscreen functionality. Good choice as the gallery is written in HTML5 and CSS3.
Several interesting features:
JavaScript. Fast start
SEO optimization
High customization
Over 10 starter templates
There is a fallback for CSS3 transitions
In my opinion, the coolest feature is the "modular script architecture", which allows you to exclude unnecessary things from the main JS file, thereby reducing weight. RoyalSlider, a jQuery image touchscreen gallery, is a robust JavaScript slider that should be a must-have for any developer's toolbox.
2. Slider Revolution responsive jQuery plugin
It's not easy to do something "revolutionary" with a slider. There are so many functions you can add when it comes to sliders. However, Slider Revolution is a really good try. Among the jQuery sliders, this instance meets all your possible requirements.
The list of slider features is so long, so I will list only the best ones:
Parallax effect and custom animation

The ability to add an image, built-in video player and social media links makes Slider Revolution one of the most flexible and customizable options on the web.
3. LayerSlider responsive jQuery slider plugin
The name "LayerSlider responsive jQuery plugin slider" cannot really appreciate this slider. 200+ 2D and 3D slide transitions will make anyone's head spin.
A couple of notable features:
13 skins and 3 types of menus
Ability to place a fixed image on top of the slider
And jQuery fallback
And much more
As with the previous slider, you can add almost any content, even HTML5 resident multimedia content. LayerSlider brings sliders to life and is very pretty.

jQuery Banner Rotator / Slideshow has only basic features compared to other jQuery sliders, but you shouldn't forget about it.
5. All In One Slider - Responsive jQuery slider plugin
Any slider that appears on the web has its own unique vision and solves any problems in its area. But not this one. All In One Slider can be called all inclusive.
I think most web developers and designers have a proven solution, but they are always looking for something new. And this "something new" includes:
Banner rotator

Playlist banner
Content slider
Carousel
All slider types support most, if not all, of the functionality that jQuery sliders need. Will All In One Slider be your all inclusive?
6. UnoSlider - Adaptive touchscreen slider
If your slider is not responsive and does not support touch screens, then you have the wrong slider. UnoSlider is correct.
This slider has found its place in the sun between simplicity and rich feature set. Functions:

We need a simple slider with automatic scrolling. Let's get started ...
Description of the slider's work.
The slides will be lined up and scrolled after a certain amount of time.
The red frame shows the visible part of the slider.
At the end of the slider, you need to duplicate the first slide. This is necessary in order to ensure scrolling from the third slide to the first. You also need to add the last slide to the beginning to be able to scroll backwards from the first slide to the third. Shown below is how the slider works in the forward direction.
When the slider reaches the end, a copy from the beginning of the slider is instantly placed in place of the last slide. Then the cycle repeats again. This creates the illusion of an endless slider.
HTML markup
First, let's make a simple auto-scrolling slider. It needs two containers to work. The first will set the size of the visible area of the slider, and the second is needed to place the sliders in it. The slider markup will look like this:
The.slider-box container sets the dimensions of the slider. The overflow: hidden property hides all elements that do not fall within the area inside the element.
The slider container is set to a large width. This is necessary so that all the slides fit into it.
Slides are aligned using the float: left property.
Below is a schematic layout of the slider blocks.
Script
The movement of the slides will be done by smoothly changing the container's slider margin-left property.
$ (function () (var width = $ (". slider-box") .width (); // Slider width. interval = 4000; // Interval for changing slides.$ (". slider img: last") .clone () .prependTo (".slider"); // A copy of the last slide is placed at the beginning.$ () .eq (1) .clone () .appendTo (".slider"); // A copy of the first slide is placed at the end.// The container.slider is shifted to the left one slide width. setInterval ("animation ()", interval); // The animation () function is run to change slides.)); function animation () (var margin = parseInt ($ (". slider") .css ("marginLeft")); // Current offset of the block. Slider width = $ (". slider-box") .width (), // Slider width. slidersAmount = $ (". slider") .children () .length; // The number of slides in the slider. if (margin! = (- width * (slidersAmount- 1))) // If the current slide is not the last one,(margin = margin- width; // then the margin value is reduced by the width of the slide.) else ( // If the last slide is shown,$ (". slider") .css ("margin-left", - width); // then the slider block returns to its starting position, margin = - width * 2; ) $ (". slider") .animate ((marginLeft: margin), 1000); // The slider block is shifted to the left by 1 slide.
}
;
The result is a simple slider with infinite automatic scrolling.
To begin with, this article was written with the goal of telling you how to create an image scrolling slider for web pages. This article is by no means educational in nature, it only serves as an example of how you can implement our object of consideration. You can use the code provided in this article as a kind of template for such developments, I hope that I will be able to convey the whole essence of what I have written to the reader in sufficient detail and in an accessible way.
And now to the point, not so long ago I needed to put a slider on one site, but after searching the Internet for ready-made scripts, I did not find anything worthwhile. some did not work as I needed, while others did not start at all without errors in the console. Use jQuery - plugins it seemed to me too uninteresting for the slider, tk. Although I will solve the problem with this, I will not have an understanding about the operation of this mechanism, and using the plugin for the sake of one slider is not very optimal. I also didn't really want to understand crooked scripts, so I decided to write my own script for the slider, which I myself will mark up as I need.
To begin with, we need to decide on the logic of the slider itself, and then proceed to the implementation, at this stage it is very important to have a clear understanding of the operation of this mechanism, because without it we cannot write code that works exactly as we want.
Our main object will be viewport, that is, a block in which we will see how our pictures are spinning, in it we will have slidewrapper, this will be our block containing all the images, lined up in one line, and which will change its position inside the very viewport.
Further, on the sides inside viewport, vertically in the middle, the back and forward buttons will be located, upon clicking on which we will also change the position of our slidewrapper relatively viewport, thereby causing the effect of scrolling through pictures. And finally, the last object will be our navigation buttons located at the bottom. viewport.
When clicking on them, we will simply look at the serial number of this button and move to the slide we need, again by shifting slidewrapper(the offset will be done through the change transform css properties, the value of which will be constantly calculated).
I think the logic of this whole case should be clear after what I have stated above, but if there are still misunderstandings somewhere, then everything will be cleared up in the code below, you just need a little patience.
Now let's write! First of all, we will open our index file and write the markup we need there:
As you can see, nothing complicated block-for-slider serves as just the same block in which our slider will be placed, inside it itself viewport in which our slidewrapper, aka nested list, here li are slides and img- pictures inside them. Please pay attention to the fact that all pictures must be of the same size or, at least, proportions, otherwise the slider will look crooked, tk. its dimensions directly depend on the aspect ratio of the image.
Now we need to stylize this whole thing, usually the styles are not really commented on, but I decided to draw attention to this, so that there would be no misunderstanding in the future.
Let's start with block-for-slider, this, again, is our block on the page, which we will set aside for the slider, its height will depend on its width and on the proportions of our image, since viewport takes up the entire width block-for-slider then myself slide has the same width, and, accordingly, the picture inside it changes its height depending on the width (the proportions are preserved). I placed this element horizontally in the middle on my page, padding 100px from the top, making its position more convenient for an example.
Element viewport, as already mentioned, occupies the entire width of our block-for-slider, it has the property overflow: hidden, it will allow us to hide our image feed, which will pop out of the viewport.
Following css property - user-select: none, allows you to get rid of the blue selection of individual slider elements with multiple clicks on the buttons.
Moving on to slidewrapper why position: relative, but not absolute? Everything is very simple, tk. if we choose the second option, then with the property viewport overflow: hidden absolutely nothing will seem to us, tk. myself viewport will not adjust to the height slidewrapper, because of what will have height: 0... Why does width matter so much, and why are we setting it at all? The fact is that our slides will have a width equal to 100% of viewport, and in order to arrange them in a line, we need a place where they will stand, thus the width slidewrapper should equal 100% viewport width multiplied by the number of slides (in my case, 4). Concerning transition and transition-timing-function then here 1s means that a change in position slidewrapper will occur within 1 second and we will observe it, and ease-in-out- the kind of animation in which it first goes slowly, accelerates to the middle, and then slows down again, here you can already set the values at your discretion.
The next block of properties sets slidewrapper and its children have zero padding, comments are unnecessary here.
Next, we will style our slides, their width should be equal to the width. viewport, but since they are in slidewrapper, the width of which is equal to the width of the viewport multiplied by the number of slides, then to get the width viewport again, we need 100% of the width slidewrapper divide by the number of slides (in my case, again, by 4). Then we turn them into inline elements using display: inline and set the flow to the left by adding the property float: left... About list-style: none I can say that I use it to remove the default marker from li, in most cases is a kind of standard.
With slide-img everything is simple, the picture will take up the entire width slide, slide adjusts to its height, slidewrapper adjusts to the height slide, and the height viewport in turn will take the value of the height slidewrapper, thus the height of our slider will depend on the aspect ratio of the image and the size of the block provided for the slider, which I already wrote about above.
I think this is where we figured out the styles, let's make a simple slide show without buttons for now, and after making sure that it works properly, add and style them.
Let's open our js file, which will contain the slider code, do not forget to include jQuery since we will write using this framework. By the way, at the time of this writing, I am using the version jQuery 3.1.0... The file with the script itself must be included at the very end of the tag body since we will be working with the DOM elements that need to be initialized first.
For now, we need to declare a couple of variables, one will store the slide number that we see at a certain point in time in viewport, I named her slideNow, and the second will store the number of these same slides, this is slideCount.
var slideNow = 1; var slideCount = $ ("# slidewrapper"). children (). length);
Variable slideNow it is necessary to set the initial value 1, because when the page loads, we, based on our markup, will see the first slide in viewport.
V slideCount we will put the number of children slidewrapper, everything is logical here. Next, you need to create a function that will be responsible for switching slides from right to left, we will declare it:
function nextSlide () ()
We will call it in the main block of our code, which we will get to, but for now we will tell our function what it needs to do:
First, we check if we are now on the last slide of our feed? To do this, we take the number of all our slides using $ ("# slidewrapper"). children (). length and check it with the number of our slide, if they turn out to be equal, then this means that we need to start showing the ribbon again, from 1 slide, which means we change css transform property at slidewrapper on translate (0, 0), thus shifting it to its original position so that the first slide appears in our field of view, do not forget also about –Webkit and –ms for adequate cross-browser display (see. css properties reference). After that, let's not forget to update the value of the variable. slideNow, informing her that slide number 1 is in her field of view: slideNow = 1;
The same condition includes checking that the number of the slide that we see is within the limits of the number of our slides, if somehow this is not fulfilled, then we will return to the 1st slide.
If the first condition is not met, then this means that at the moment we are not on the last slide, or on some nonexistent one, which means we need to switch to the next one, we will do it by shifting slidewrapper to the left by a value equal to the width viewport, the displacement will again occur through the familiar property translate whose value will be equal to "translate (" + translateWidth + "px, 0)", where translateWidth- the distance by which our slidewrapper... By the way, let's declare this variable at the beginning of our code:
var translateWidth = 0;
After moving to the next slide, tell our slideNow that we see the next slide: slideNow ++;
At the moment, some readers may have a question: why did not we replace $ ("# viewport"). width () to some variable, for example slideWidth to always have the width of our slide at hand? The answer is very simple, if our site is responsive, then, accordingly, the block allocated for the slider is also adaptive, from this it can be understood that when changing the size of the window width without reloading the page (for example, turning the phone sideways), the width viewport will change, and, accordingly, the width of one slide will also change. In this case, our slidewrapper will be shifted by the value of the width that was originally, which means that the pictures will be displayed in parts or not at all displayed in viewport... By writing to our function $ ("# viewport"). width () instead of slideWidth we make it calculate the width every time we switch slides viewport, thereby providing a scroll to the desired slide when the screen width changes abruptly.
However, we wrote the function, now we need to call it after a certain time interval, we can also store the interval in a variable, so that if we want to change it, change only one value in the code:
Everything is nowhere easier, we are through the construction $ (document) .ready (function () ()) we say that the following actions must be performed after the document is fully loaded. Then we just call the function nextSlide with an interval equal to slideInterval, using the built-in function setInterval.
After all the actions that we performed above, our slider should spin fine, but if something went wrong with you, then the problem may be either in the version jQuery, or in the wrong connection of any files. Also, it is not necessary to exclude that you could have made a mistake somewhere in the code, so I can only advise you to double-check everything.
In the meantime, move on, add to our slider such a function as stop scrolling on hover, for this we need to write in the main block of code (inside $ (document) .ready (function () ())) such a thing:
To start analyzing this code, we need to know what is switchInterval... Firstly, this is a variable that stores a periodic call to the nextSlide function, to put it simply, we use this line of code: setInterval (nextSlide, slideInterval);, turned into this: switchInterval = setInterval (nextSlide, slideInterval);... After these manipulations, our main block of code took the following form:
Here I am using event hover, which means "on hover", this event allows me to track the moment when I hover over an object, in this case on viewport.
After hovering, I clear the spacing, which I will indicate in parentheses (this is our switchInterval), then, separated by commas, I write what I will do when I move the cursor back, in this block I again assign to our switchInterval periodic function call nextSlide.
Now, if we check, we will see how our slider reacts to mouse hover, stopping the slide switching.
Now it's time to add buttons to our slider, let's start with the back and forth buttons.
First of all, let's mark them up:
At first, this markup may be incomprehensible, I will say right away that I wrapped these two buttons into one div with class prev-next-btns just for your convenience, you do not have to do this, the result will not change, now we will add styles to them and everything will become clear:
First, we position our buttons via position: absolute, thereby we will freely control their position within our viewport, then we will indicate the sizes of these buttons and using border-radius round the corners so that these buttons turn into circles. Their color will be white, that is #fff, and their indent from the top edge viewport will be equal to half the height of this viewport minus half the height of the button itself (in my case 25px) so we can position them vertically in the center. Next, we will indicate that when we hover over them, our cursor will change to pointer and finally tell our buttons individually to indent 20px from their edges so that we can see them as we see fit.
Again, you can style the page elements however you want, I am just giving an example of the styles that I decided to use.
After styling, our slider should look something like this:
Next, go back to our js file where we describe how our buttons work. Well, let's add another function, it will show us the previous slide:
It is called prevSlide, it will be called only when you click on prev-btn... First, we check to see if we are on the 1st slide or not, here we also check if our slideNow beyond the boundaries of the real range of our slides and, if any of the conditions works, we will move to the last slide by shifting slidewrapper to the value we need. We will calculate this value by the formula: (width of one slide) * (number of slides - 1), we take all this with a minus sign, since we shift it to the left, it turns out that viewport will now show us the last slide. At the end of this block, we also need to tell the variable slideNow that the last slide is now in our field of vision.
If we are not on the first slide, then we need to move 1 backward, for this we again change the property transform for slidewrapper... The formula is as follows: (width of one slide) * (number of the current slide - 2), again, we take all this with a minus sign. But why is -2, and not -1, do we need to move just 1 slide back? The fact is that if we are, say, on the 2nd slide, then the variable x properties transform: translate (x, 0) our slidewrapper is already equal to the width of one slide, if we tell him that we need to subtract 1 from the number of the current slide, then we will again get the unit by which it is already shifted slidewrapper, so you will need to shift these very widths by 0 viewport, which means on slideNow - 2.
Now we just need to add these lines to the main block of code:
Here we just track whether a click was made on our buttons, and in this case we call the functions we need, everything is simple and logical.
Now let's add the slide navigation buttons, back to the markup:
As you can see, inside viewport a nested list appeared, give it an identifier nav-btns, inside it li- our navigation buttons, we will assign a class to them slide-nav-btn, however, we can finish with the markup, let's get down to the styles:
Blok nav-btns, in which our buttons are located, we give the property position: absolute, so that it does not stretch viewport in height, because at slidewrapper property position: relative, we set the width to 100% so that using text-align: center center buttons horizontally relative viewport, then using the property bottom we make it clear to our block that it should be at a distance of 20px from the bottom edge.
We do the same with the buttons as with the slides, but now we set them display: inline-block since at display: inline they don't react to width and height since are in an absolutely positioned block. We will make them white and with the help of the already familiar to us border-radius let's give them a circle shape. When you hover over them, we will change the appearance of our cursor for the usual display.
Now let's get down to jQuery - parts: First, let's declare the navBtnId variable, which will store the index of the button we clicked:
Here we are when clicking on our slide-nav-btn we call the function, which first of all assigns to the variable navBtnId the index of the clicked button, that is, its ordinal number, since the counting starts from zero, then if we click on the second button, then in navBtnId the value is written 1. Next, we do a check, where we add one to the serial number of the button to get such a number as if the countdown was not from 0, but from 1, we compare this number with the number of the current slide, if they coincide, then we will not take no action, because the desired slide is already in viewport.
If the slide we need is out of sight viewport, then we calculate the distance by which we need to shift slidewrapper to the left, then change the value css transform properties on translate(the same distance in pixels, 0). We have already done this more than once, so there should be no questions. At the end, we save the value of the current slide to a variable again. slideNow, this value can be calculated by adding one to the index of the clicked button.
That's all, in fact, if something is not clear, then I leave a link to the jsfiddle, where all the code written in the material will be provided.
Thank you for the attention!
