<div class="pull-left"> <h1> First </h1></div><br /> you need to put that break tag in before the second word, it pushes the first line of text down 1 line so it looks nicer.
<br /><br />
It took a lot of < to make those not get parsed into layout though :) Oh, also don't forget the double break below this block, and a blank line after, like above, or the second paragraph does not have a space between it and the first.
