Image Transition with CSS 3 ( pseudo elements )

In this tutorial, we are going to learn  how to use transitions with pseudo elements on CSS 3. We were not able to create an image slider with CSS 2 before. In order to create one, we needed to use JS too. But CSS 3 brought us many new features includes transition elements. So we don't need a JavaScript to create an image gallery/slider or rotating background images. All we need is to use pseudo elements in CSS 3 and basic HTML. And of course its also up to what do you want.

You can reach my DEMO from here. Please let me know if you have any questions.

and here HTML and CSS 3 codes.


HTML 

<div id="crossfade">
    <img src="img/contact.jpg"   alt=""/>
    <img src="img/cheesey.jpg"   alt=""/>
    <img src="img/squash.jpg"    alt=""/>
    <img src="img/brushado.jpg"  alt=""/>
    <img src="img/Crudite.jpg"   alt=""/>
</div>
