Responsive Images

Images come in all sizes. So do screens. Responsive images automatically adjust to fit the size of the screen.

Create responsive images by adding an .img-responsive class to the <img> tag. The image will then scale nicely to the parent element.

The .img-responsive class applies display: block; and max-width: 100%; and height: auto; to the image:

Image Gallery

You can also use Bootstrap's grid system in conjunction with the .thumbnail class to create an image gallery.

Lorem ipsum donec id elit non mi porta gravida at eget metus.

Note: You will learn more about the Grid System later in this tutorial (how to create a layout with different amount of columns).

Example

<div class="row">
<div class="col-md-4">
    <div class="thumbnail">
      <a href="/w3images/lights.jpg">
        <img src="/w3images/lights.jpg" alt="Lights" style="width:100%">
        <div class="caption">
          <p>Lorem ipsum...</p>
        </div>
      </a>
    </div>
</div>
<div class="col-md-4">
    <div class="thumbnail">
      <a href="/w3images/nature.jpg">
        <img src="/w3images/nature.jpg" alt="Nature" style="width:100%">
        <div class="caption">
          <p>Lorem ipsum...</p>
        </div>
      </a>
    </div>
</div>
<div class="col-md-4">
    <div class="thumbnail">
      <a href="/w3images/fjords.jpg">
        <img src="/w3images/fjords.jpg" alt="Fjords" style="width:100%">
        <div class="caption">
          <p>Lorem ipsum...</p>
        </div>
      </a>
    </div>
</div>
</div>

Responsive Embeds

Also let videos or slideshows scale properly on any device.

Classes can be applied directly to <iframe>, <embed>, <video>, and <object> elements.

The following example creates a responsive video by adding an .embed-responsive-item class to an <iframe> tag (the video will then scale nicely to the parent element). The containing <div> defines the aspect ratio of the video:

What is aspect ratio?

The aspect ratio of an image describes the proportional relationship between its width and its height. Two common video aspect ratios are 4:3 (the universal video format of the 20th century), and 16:9 (universal for HD television and European digital television).

You can choose between two aspect ratio classes:

<div class="embed-responsive embed-responsive-16by9">
<iframe class="embed-responsive-item" src="..."></iframe>
</div>


<div class="embed-responsive embed-responsive-4by3">
<iframe class="embed-responsive-item" src="..."></iframe>
</div>
