I can't get past this section, every time I submit my code there is an error that comes up. I can't figure out what I did wrong with this piece of code. PS: when I open the webpage the images look fine.
Here is the code I wrote for this section. I added two "thumbnail classes in order to add two pictures to the webpage, but it's the error keeps happening:
<div class="learn-more"> <div class="container"> <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> <h3>Travel</h3> <p>From apartments and rooms to treehouses and boats: stay in unique spaces in 192 countries.</p> <p><a href="#">See how to travel on Airbnb</a></p> </div>
