This slider has a 100% width layout and it is responsive. It operates with CSS transitions and the image is wrapped with an anchor. The anchor can be replaced by a division if no linking is needed. With a max-width set to 100%, the image will size down for smaller screens.

The HTML

<div id="cbp-fwslider" class="cbp-fwslider">
	<ul>
		<li><a href="#"><img src="images/1.jpg" alt="img01"/></a></li>
		<li><a href="#"><img src="images/2.jpg" alt="img02"/></a></li>
		<li><a href="#"><img src="images/3.jpg" alt="img03"/></a></li>
		<li><a href="#"><img src="images/4.jpg" alt="img04"/></a></li>
		<li><a href="#"><img src="images/5.jpg" alt="img05"/></a></li>
	</ul>
</div>
