In the following tutorial we will create an asymmetrical image slider with a little twist: when sliding the pictures we will slightly rotate them and delay the sliding of each element. The unusual shape of the slider is created by some elements placement and the use of thick borders. We will also add an autoplay option and the mousewheel functionality.

We’ll use the jQuery 2D Transformation Plugin for rotating the images and the jQuery Mousewheel Plugin by Brandon Aaron for the mousewheel control.

Allrighty! Let’s start with the HTML!

The Markup

First, we will wrap all our slider elements in a wrapper with the class “rm_wrapper”:

<div class="rm_wrapper">
...
</div>

Inside of that wrapper we will have a container for the actual slider list, some mask and corner elements, the heading and a hidden div that will contain all the image sets:

<div id="rm_container" class="rm_container">
	<ul>
		<li data-images="rm_container_1" data-rotation="-15">
			<img src="images/1.jpg"/>
		</li>
		<li data-images="rm_container_2" data-rotation="-5">
			<img src="images/2.jpg"/>
		</li>
		<li data-images="rm_container_3" data-rotation="5">
			<img src="images/3.jpg"/>
		</li>
		<li data-images="rm_container_4" data-rotation="15">
			<img src="images/4.jpg"/>
		</li>
	</ul>
	<div id="rm_mask_left" class="rm_mask_left"></div>
	<div id="rm_mask_right" class="rm_mask_right"></div>
	<div id="rm_corner_left" class="rm_corner_left"></div>
	<div id="rm_corner_right" class="rm_corner_right"></div>
	<h2>Fashion Explosion 2012</h2>
	<div style="display:none;">
		<div id="rm_container_1">
			<img src="images/1.jpg"/>
			<img src="images/5.jpg"/>
			<img src="images/6.jpg"/>
			<img src="images/7.jpg"/>
		</div>
		<div id="rm_container_2">
			<img src="images/2.jpg"/>
			<img src="images/8.jpg"/>
			<img src="images/9.jpg"/>
			<img src="images/10.jpg"/>
		</div>
		<div id="rm_container_3">
			<img src="images/3.jpg"/>
			<img src="images/11.jpg"/>
			<img src="images/12.jpg"/>
			<img src="images/13.jpg"/>
		</div>
		<div id="rm_container_4">
			<img src="images/4.jpg"/>
			<img src="images/14.jpg"/>
			<img src="images/15.jpg"/>
			<img src="images/16.jpg"/>
		</div>
	</div>
</div>

So the unordered lists will have the first set of four images where each list element has some data attributes for the image sets and the rotation degree. We will use that data to know which images come next and how much each image should be rotated.

The mask and corner divs will be absolute elements that we will place on top of the slider, slightly rotated in order to cover some areas. Since we will use the same background color for these elements like the body’s background color, we will create the illusion of the images being shaped in a certain way.

Then we’ll add the elements for the navigation and the autoplay controls:

<div class="rm_nav">
	<a id="rm_next" href="#" class="rm_next"></a>
	<a id="rm_prev" href="#" class="rm_prev"></a>
</div>
<div class="rm_controls">
	<a id="rm_play" href="#" class="rm_play">Play</a>
	<a id="rm_pause" href="#" class="rm_pause">Pause</a>
</div>

Let’s take a look at the CSS.

The CSS

First, we’ll reset some styles and define the properties for the body. (Remember, if we would have another background color, we would want to change the background and border colors of some of the elements in our slider, too.)

@import url('reset.css');
body{
	background:#f0f0f0;
	color:#000;
	font-family: 'PT Sans Narrow', Arial, sans-serif;
	font-size:16px;
}
a{
	color:#000;
	text-decoration:none;
}
h1{
	padding:10px;
	margin:20px;
	font-size:40px;
	text-transform:uppercase;
	text-shadow:0px 0px 1px #fff;
	color:#333;
	background:transparent url(../images/line.png) repeat-x bottom left;
}

The main wrapper will have the following style:

.rm_wrapper{
	width:1160px;
	margin:0 auto;
	position:relative;
}

The container for the slider will have any overflow hidden, which will help shaping our slider since we will cut off the outer sides of it:

.rm_container{
	width:1050px;
	overflow:hidden;
	position:relative;
	height:530px;
	margin:0 auto;
}

The heading will have the following style:

.rm_container h2{
	background:transparent url(../images/lines.png) repeat top left;
	padding:10px 30px;
	position:absolute;
	bottom:170px;
	right:0px;
	color:#000;
	font-size:36px;
	text-transform:uppercase;
	text-shadow:1px 0px 1px #fff;
}

Let’s define the width for the ul to be bigger than the container since we want to make the list element float next to each other:

.rm_container ul{
	width:1170px;
}

By giving a negative left margin and a thick border to the list element, we will overlap the images and cut off the right sides so that we create our asymmetrical shapes by rotating the elements then. The border color will be the same like the background color of the body (or the container).

.rm_container ul li{
	float:left;
	margin-left:-80px;
	position:relative;
	overflow:hidden;
	width:310px;
	height:465px;
	border:30px solid #f0f0f0;
	border-width:50px 30px 0px 30px;
	background-color:#f0f0f0;
}

We’ll position the images absolutely:

.rm_container ul li img{
	position:absolute;
	top:0px;
	left:0px;
}

In the following we will style the mask and the corner elements. They will be all positioned absolutely and we’ll give them the grey background color. By rotating them, we’ll make the images to appear as being “shaped”:

.rm_mask_right, .rm_mask_left{
	position: absolute;
	height: 110px;
	background: #f0f0f0;
	width: 530px;
	bottom: -30px;
	left: 0px;
	-moz-transform:rotate(-3deg);
	-webkit-transform:rotate(-3deg);
	transform:rotate(-3deg);
}
.rm_mask_right{
	left:auto;
	right:0px;
	-moz-transform:rotate(3deg);
	-webkit-transform:rotate(3deg);
	transform:rotate(3deg);
}
.rm_corner_right, .rm_corner_left{
	background: #f0f0f0;
	position:absolute;
	width:200px;
	height:100px;
	bottom:0px;
	left:-65px;
	-moz-transform:rotate(45deg);
	-webkit-transform:rotate(45deg);
	transform:rotate(45deg);
}
.rm_corner_right{
	left:auto;
	right:-65px;
	-moz-transform:rotate(-45deg);
	-webkit-transform:rotate(-45deg);
	transform:rotate(-45deg);
}

The navigation elements will be placed to the left and right of the main container:

.rm_nav a{
	position:absolute;
	top:200px;
	width:38px;
	height:87px;
	cursor:pointer;
	opacity:0.7;
}
.rm_nav a:hover{
	opacity:1.0;
}
.rm_nav a.rm_next{
	background:transparent url(../images/next.png) no-repeat top left;
	right:0px;
}
.rm_nav a.rm_prev{
	background:transparent url(../images/prev.png) no-repeat top left;
	left:0px;
}

The pause/play control will be placed to the top left of the main container:

.rm_controls{
	position:absolute;
	top:0px;
	left:-40px;
	height:20px;
}
.rm_controls a{
	cursor:pointer;
	opacity:0.7;
	padding-left:24px;
	font-size:16px;
	text-transform:uppercase;
	height:20px;
	float:left;
	line-height:20px;
}
.rm_controls a:hover{
	opacity:1.0;
}
.rm_controls a.rm_play{
	display:none;
	background:transparent url(../images/play.png) no-repeat center left;
}
.rm_controls a.rm_pause{
	background:transparent url(../images/pause.png) no-repeat center left;
}

And that’s all the style! Let add the spice!

The JavaScript

The main idea for the slider functionality is to add another image before the current one with a slightly increased rotation degree than the current item. Then we will animate the rotation and make the new images appear.
So let’s start by caching some elements and checking if we are dealing with a special needs browser in order to deal with some issues:

//our 4 items	
var $listItems 		= $('#rm_container > ul > li'),
	totalItems		= $listItems.length,
	
	//the controls
	$rm_next		= $('#rm_next'),
	$rm_prev		= $('#rm_prev'),
	$rm_play		= $('#rm_play'),
	$rm_pause		= $('#rm_pause'),
	
	//the masks and corners of the slider
	$rm_mask_left	= $('#rm_mask_left'),
	$rm_mask_right	= $('#rm_mask_right'),
	$rm_corner_left	= $('#rm_corner_left'),
	$rm_corner_right= $('#rm_corner_right'),
	
	//check if the browser is <= IE8
	ieLte8			= ($.browser.msie && parseInt($.browser.version) <= 8),

Then we will define our main function:

RotateImageMenu	= (function() {
...
})();
	
RotateImageMenu.init();

And then we define the following in our function:

	//difference of animation time between the items
var	timeDiff			= 300,
	//time between each image animation (slideshow)
	slideshowTime		= 3000,
	slideshowInterval,	
	//checks if the images are rotating
	isRotating			= false,
	//how many images completed each slideshow iteration
	completed			= 0,
	/*
	all our images have 310 of width and 465 of height.
	this could / should be dynamically calculated 
	if we would have different image sizes.
	
	we will set the rotation origin at 
	x = width/2 and y = height*2
	*/
	origin				= ['155px', '930px'],
	init				= function() {
		configure();
		initEventsHandler();
	},
	//initialize some events
	initEventsHandler	= function() {
		/*
		next and previous arrows:
		we will stop the slideshow if active,
		and rotate each items images.
		1 	rotate right
		-1 	rotate left
		*/
		$rm_next.bind('click', function(e) {
			stopSlideshow();
			rotateImages(1);
			return false;
		});
		$rm_prev.bind('click', function(e) {
			stopSlideshow();
			rotateImages(-1);
			return false;
		});
		/*
		start and stop the slideshow
		*/
		$rm_play.bind('click', function(e) {
			startSlideshow();
			return false;
		});
		$rm_pause.bind('click', function(e) {
			stopSlideshow();
			return false;
		});
		/*
		adds events to the mouse and left / right keys
		*/
		$(document).bind('mousewheel', function(e, delta) {
			if(delta > 0) {
				stopSlideshow();
				rotateImages(0);
			}	
			else {
				stopSlideshow();
				rotateImages(1);
			}	
			return false;
		}).keydown(function(e){
			switch(e.which){
				case 37:
					stopSlideshow();
					rotateImages(0);
					break;
				case 39:
					stopSlideshow();
					rotateImages(1);
					break;
			}
		});
	},
	/*
	rotates each items images.
	we set a delay between each item animation
	*/
	rotateImages		= function(dir) {
		//if the animation is in progress return
		if(isRotating) return false;
		
		isRotating = true;
		
		$listItems.each(function(i) {
			var $item 				= $(this),
				/*
				the delay calculation.
				if rotation is to the right, 
				then the first item to rotate is the first one,
				otherwise the last one
				*/
				interval			= (dir === 1) ? i * timeDiff : (totalItems - 1 - i) * timeDiff;
			
			setTimeout(function() {
					//the images associated to this item
				var	$otherImages		= $('#' + $item.data('images')).children('img'),
					totalOtherImages	= $otherImages.length;
					
					//the current one
					$img				= $item.children('img:last'),
					//keep track of each items current image
					current				= $item.data('current');
					//out of bounds 
					if(current > totalOtherImages - 1)
						current = 0;
					else if(current < 0)
						current = totalOtherImages - 1;
					
					//the next image to show and its 
					//initial rotation (depends on dir)
					var otherRotation	= (dir === 1) ? '-30deg' : '30deg',
						$other			= $otherImages.eq(current).clone();
						
					//for IE <= 8 we will not rotate, 
					//but fade out / fade in ... 
					//better than nothing πŸ™‚	
					if(!ieLte8)
						$other.css({
							rotate	: otherRotation,
							origin	: origin
						});
					
					(dir === 1) ? ++current : --current;
					
					//prepend the next image to the <li>
					$item.data('current', current).prepend($other);

					else {
						$img.fadeOut(1200, function(){

							if(completed === 4) {
								completed = 0;
								isRotating = false;
							}
						});
					}
					
			}, interval );	
		});
		
	},
	//set initial rotations
	configure			= function() {
		if($.browser.msie && !ieLte8)
			rotateMaskCorners();
		else if(ieLte8)
			hideMaskCorners();
			
		$listItems.each(function(i) {
			//the initial current is 1 
			//since we already showing the first image
			var $item = $(this).data('current', 1);
			
			if(!ieLte8)
			$item.transform({rotate: $item.data('rotation') + 'deg'})
				 .find('img')
				 .transform({origin: origin});
		});
	},
	//rotates the masks and corners
	rotateMaskCorners	= function() {
		$rm_mask_left.transform({rotate: '-3deg'});
		$rm_mask_right.transform({rotate: '3deg'});
		$rm_corner_left.transform({rotate: '45deg'});
		$rm_corner_right.transform({rotate: '-45deg'});
	},
	//hides the masks and corners
	hideMaskCorners		= function() {
		$rm_mask_left.hide();
		$rm_mask_right.hide();
		$rm_corner_left.hide();
		$rm_corner_right.hide();
	},
	startSlideshow		= function() {
		clearInterval(slideshowInterval);
		rotateImages(1);
		slideshowInterval	= setInterval(function() {
			rotateImages(1);
		}, slideshowTime);
		//show the pause button and hide the play button
		$rm_play.hide();
		$rm_pause.show();
	},
	stopSlideshow		= function() {
		clearInterval(slideshowInterval);
		//show the play button and hide the pause button
		$rm_pause.hide();
		$rm_play.show();
	};

return {init : init};

As you noticed, we will treat older browsers a bit differently so that the slider works properly.

And that’s it! We really hope you enjoyed the tutorial and like the result!

  1. Hi, i’m the author who sell the Suerte theme, with this slider.
    Before to integrate your slider in my WordPress theme i saw your copyright page (now you replaced it?) where you said that we are free to use your works also in commercial project, but we have to give you credits for your work.

    In my themeforest page, in the description of the theme, i write “Rotating slider: thanks to Tympanus.net (with link to this page)
    The beautiful photos are by Andrew and Lili and you can see their Behance profile here: http://www.behance.net/AndrewLili

    I provided credits to you and to photo’s author.

    Let me know if it’s an problem for you. Thank you S.

    • Hi Sara,
      please don’t worry, all our work is for free and you can of course use it commercially. We appreciate the link back, but what is more important is the license for the images which is Attribution-NonCommercial 3.0 Unported (CC BY-NC 3.0) which does not allow a commercial use. So you might be required to change the images that you are using for the slider.
      @Hi, thank you for your concern, but there is really no problem that somebody uses our things – we do them so that they can be used without worrying about a license. What we wouldn’t like to see is if somebody would only take the components and sell them, as they are, without integrating them somehow. We’ve had cases like that and we don’t like it for one reason: People that buy it waste their money on something that is for free, and that, in my opinion is pretty mean.
      Thanks again to both of you,
      cheers,
      ML

  2. thank you so much. I’ll replace images in the slider, thanks.

    I really love your works, and some times ago i sent a message using the contact form in this site asking the price for a custom slider, but i still wait a reply πŸ™‚

  3. (However, i don’t sell the images, i use the photos only in our live preview!)

  4. This must be the best jQuery image slider I’ve ever seen. It is a shame that it doesn’t work in Google Chrome (12.0.742.122).

  5. In Chrome – disable AdBlock, and reload it works…

    something triggers it… (both here and Suerte’s theme as well)

  6. Demo is working bad on Firefox. First and last images shown on outside of their areas for a while when on amination.

  7. Is there anyway to make the slider much smaller and only feature 2 items? Can each of those items click through to different links?

  8. That’s a great slide show you have. However, Firefox could not detects the position of the data-rotation. Causing problem for me to use this layout.

    It allows me the first set of 4 images to rotate and none would appear next. πŸ™

  9. Hey Mary Lou,

    First of all.. :
    Thank you VERY much for all of these nice examples!

    I would like to use part of this script to make a little (products-)banner.

    Unfortunately, I do not seem to be able to put a (external) link to the pictures, div’s or ..anything for that matter. And since they rotate it is not an option to put a floating div on top..

    I also saw that others where also not able to do so..
    (Alex, Mark, Luca, Tabitha and Me)

    Could you please help us/me out?
    (using Safari)

    Many thanks so far!

  10. I was loading the demo in IE8, is it suppose to not curve and rotate like FireFox and Chrome?

    it just slides and fades… is it by design to do that?

  11. It’s funny, I had a client come to me earlier today and ask me to create a slideshow in this exact fashion for them using jquery. I was devising a plan to write the code, and while taking a break, I stumbled upon this article. Exactly what I needed. Thank you 100 times!

  12. Hi..This is amzing..I think of using it in one of my websites. But my website has a background image. Si in this situation how will I use this.

  13. Great work as always Mary Lou!

    But Is there anyway to make the slider much smaller ?

    Many thanks πŸ™‚

  14. Like many others on here, I’d like to be able to link the images and/or place a caption/tooltip on them. Has anyone found a solution to this yet?
