Elastic Content Slider

A fluid content slider that will adjust in width and height depending on the size of its parent.

This Blueprint is a simple jQuery content slider. It has a sliding area for content and a tab-like navigation at the bottom. The slider is fluid, meaning that it will adjust to the parent’s container width and height. A couple of media queries show how to minimalise the look by just leaving icons for the navigation when the screen is very small. The content area will become scrollable if there isn’t enough space available. Every list item is a slide and and it has a corresponding link element in the navigation.

Note that we don’t show vendor prefixes here, but you’ll find them in the files. Also note that we use box-sizing: border-box by default for all elements.

    Hi, i want two content slider component on single page. is this possible? I had tried but only one is working.

    • 3

      I found a work around, by destroying one slider but the problem is that on second slider class “rc-active” is not added on second slider.

    • 4

      I found it:

      Just add a second and give it anohter ID

      $(function() {
      $( ‘#contentslider_work’ ).cbpContentSlider();
      });

      $(function() {
      $( ‘#contentslider_about’ ).cbpContentSlider();
      });
