Neighborhood EX. 7


#1

Can't seem to understand why I am being asked to create a new <div class="thumbnail"> </div>

My code:

<div class="neighborhood-guides">
<div class="container">
<h2>Neighborhood Guides</h2>
<p>Not sure where to stay? We've created neighborhood guides for cities all around the world</p>
<div class="row">
<div class="col-md-4">
<div class="thumbnail">
<img src="http://goo.gl/0sX3jq">
</div>
<div class="thumbnail">
<img src="http://goo.gl/an2HXY">
</div>
<div class="col-md-4">
<div class="thumbnail">
<img src="http://goo.gl/Av1pac">
</div>
<div class="thumbnail">
<img src="http://goo.gl/vw43v1">
</div>
</div>
<div class="col-md-4">
<div class="thumbnail">
<img src="http://goo.gl/Okd7UO">
</div>
</div>
</div>
</div>
</div>

That's because the code checker can't find your second column. You haven't closed your first column so the second column is nested inside the first one.
