A very simple 100% width slider that scales down to mobile.
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>

Hello!
This is a beautiful plugin! I’m using it to develop a website and on my localhost it works flawless. However, it doesn’t seem to work when I copy a mirror of my layout to a server. I’m not the kind of person to ask for this kind of help on websites, but it’s beyond my skillz.
Is there a way to find out what is creating the conflict? The relative paths and such are working fine. Could there be any possibilities of plugin conflict for this plugin that you know of? Thank you!
Hi,
How can I make this fade rather than slide?
My problem is Modernizr is undefined.How can i fix it.Thank you
This is a great tutorial and slider. How can I implement timed transitions?
Hi! Thanks, it best slider. But please, ask me, how add easing effect change slide “FADE”?
