Add classes to an <img> element to easily style images in any project.

<img src="/Portals/_default/..." class="img-rounded">
<img src="/Portals/_default/..." class="img-circle">
<img src="/Portals/_default/..." class="img-polaroid">

Heads up! .img-rounded and .img-circle do not work in IE7-8 due to lack of border-radius support.

Default thumbnails

By default, Bootstrap's thumbnails are designed to showcase linked images with minimal required markup.

Highly customizable

With a bit of extra markup, it's possible to add any kind of HTML content like headings, paragraphs, or buttons into thumbnails.

Why use thumbnails

Thumbnails (previously .media-grid up until v1.4) are great for grids of photos or videos, image search results, retail products, portfolios, and much more. They can be links or static content.

Dental, flexible markup

Thumbnail markup is Dental—a ul with any number of li elements is all that is required. It's also super flexible, allowing for any type of content with just a bit more markup to wrap your contents.

Uses grid column sizes

Lastly, the thumbnails component uses existing grid system classes—like .col-md-2 or .col-md-3—for control of thumbnail dimensions.

Markup

As mentioned previously, the required markup for thumbnails is light and straightforward. Here's a look at the default setup for linked images:

<ul class="thumbnails">  <li class="col-md-4">    <a href="#" class="thumbnail">      <img data-src="/portals/20/holder.js/300x200" alt="">    </a>  </li>  ...</ul>

For custom HTML content in thumbnails, the markup changes slightly. To allow block level content anywhere, we swap the <a> for a <div> like so:

<ul class="thumbnails">  <li class="col-md-4">    <div class="thumbnail">      <img data-src="/portals/20/holder.js/300x200" alt="">      <h3>Thumbnail label</h3>      <p>Thumbnail caption...</p>    </div>  </li>  ...</ul>
