Description:

A pure CSS slider component that each new image slides over the previous one with CSS3 animations.

How to use it:

Add a list of images to the slider.

<ul class="slides">
  <li class="first" id="slide-1"><img src="1.jpg"></li>
  <li id="slide-2"><img src="2.jpg"></li>
  <li id="slide-3"><img src="3.jpg"></li>
  <li id="slide-4"><img src="4.jpg"></li>
  <li id="slide-5"><img src="5.jpg"></li>
  <li id="slide-6"><img src="6.jpg"></li>
  <li id="slide-7"><img src="7.jpg"></li>
</ul>

Create a thumbnails navigation for the slider.

<ul class="thumbs">
  <li><a href="#slide-1"><img src="thumb1.jpg"><span>This is image 1</span></a></li>
  <li><a href="#slide-2"><img src="thumb2.jpg"><span>This is image 2</span></a></li>
  <li><a href="#slide-3"><img src="thumb3.jpg"><span>This is image 3</span></a></li>
  <li><a href="#slide-4"><img src="thumb4.jpg"><span>This is image 4</span></a></li>
  <li><a href="#slide-5"><img src="thumb5.jpg"><span>This is image 5</span></a></li>
  <li><a href="#slide-6"><img src="thumb6.jpg"><span>This is image 6</span></a></li>
  <li><a href="#slide-7"><img src="thumb7.jpg"><span>This is image 7</span></a></li>
</ul>
