Components

Dozens of reusable components are built into Bootstrap to provide navigation, alerts, popovers, and much more.

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.

  • Thumbnail label

    Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.

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.

Simple, flexible markup

Thumbnail markup is simple—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 .span2 or .span3—for control of thumbnail dimensions.

The 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="span3">
    <a href="#" class="thumbnail">
      <img src="http://placehold.it/210x150" 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="span3">
    <div class="thumbnail">
      <img src="http://placehold.it/210x150" alt="">
      <h5>Thumbnail label</h5>
      <p>Thumbnail caption right here...</p>
    </div>
  </li>
  ...
</ul>

Basic alerts

.alert-message

One-line messages for highlighting the failure, possible failure, or success of an action. Particularly useful for forms.

Holy guacamole! Best check yo self, you’re not looking too good.

Oh snap! Change this and that and try again.

Well done! You successfully read this alert message.

Heads up! This is an alert that needs your attention, but it’s not a huge priority just yet.

Example code

<div class="alert-message warning">
  <a class="close" href="#">×</a>
  <p><strong>Holy guacamole!</strong> Best check yo self, you’re not looking too good.</p>
</div>

Block messages

<div class="alert-message block-message">

For messages that require a bit of explanation, we have paragraph style alerts. These are perfect for bubbling up longer error messages, warning a user of a pending action, or just presenting information for more emphasis on the page.

Modals

Modals—dialogs or lightboxes—are great for contextual actions in situations where it’s important that the background context be maintained.
