───→</div>↲
───→<div class="col-md-4">...
With ↲ being a new line, and ───→ being a tab. You have space! The "quotes" you see are the DOM inspector saying "here's a text node", they're not in the source. All that's in your source, is the whitespace that you put there.
Try:
</div><div class="col-md-4">...
