 <p>Yes you need image responsive. I think instead of featured-work should be container instead</p> <pre><code> &lt;div class="container"&gt; &lt;div class="row row-work"&gt; &lt;div class="col-md-6"&gt; &lt;img class="img-responsive" src="http://lorempixel.com/600/400/"&gt; &lt;/div&gt; &lt;div class="col-md-6"&gt; &lt;img class="img-responsive" src="http://lorempixel.com/600/400/"&gt; &lt;/div&gt; &lt;/div&gt; &lt;div class="row row-work"&gt; &lt;div class="col-md-6"&gt; &lt;img class="img-responsive" src="http://lorempixel.com/600/400/"&gt; &lt;/div&gt; &lt;div class="col-md-6"&gt; &lt;img class="img-responsive" src="http://lorempixel.com/600/400/"&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; </code></pre>
