Responsive Images
Images comes 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:
Example
<div class="row">
<div class="col-md-4">
<a href="pulpitrock.jpg" class="thumbnail">
<p>Pulpit Rock: A famous tourist attraction in Forsand, Ryfylke, Norway.</p>
<img src="pulpitrock.jpg" alt="Pulpit
Rock" style="width:150px;height:150px">
</a>
</div>
<div
class="col-md-4">
<a href="moustiers-sainte-marie.jpg"
class="thumbnail">
<p>Moustiers-Sainte-Marie:
Considered as one of the "most beautiful villages of France".</p>
<img src="moustiers-sainte-marie.jpg" alt="Moustiers Sainte Marie"
style="width:150px;height:150px">
</a>
</div>
<div class="col-md-4">
<a href="cinqueterre.jpg" class="thumbnail">
<p>The Cinque Terre: A rugged portion of coast in the Liguria region of
Italy.</p>
<img src="cinqueterre.jpg"
alt="Cinque Terre" style="width:150px;height:150px">
</a>

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

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:
<!-- 16:9 aspect ratio -->
<div class="embed-responsive embed-responsive-16by9">
<iframe
class="embed-responsive-item" src="..."></iframe>
</div>
<!-- 4:3 aspect ratio -->
<div class="embed-responsive embed-responsive-4by3">
<iframe
class="embed-responsive-item" src="..."></iframe>
</div>
