Below is the code I have typed out. I can't seem to figure out was what wrong. So please help.
It would be helpful if you write what the error text is.
3 posts were split to a new topic: 6. Oops, try again. Add a div class="thumbnail"../div
You didn't close the div col-md-4
Posting your full code would help, but, in the meantime, did you put your thumbnail divs inside the first col-md-4 div inside the neighborhood-guides div?
