<div id="article" class="animated2 fadeInLeftBig">

<div class="category">#Category</div>
<h1>This is the H1</h1>
<p class="intro">Lorem ips um dolor sit amet, consectetur adipiscing elit. Nam sit amet diam nisl. Aliquam quis est eu elit facilisis aliquam. Pellentesque porta nunc diam <a class="various" href="#">Inline</a></p>

Answer 1

You should clear: both; on the h1 tag. An alternative would be to create a clear:both; <div>, but that isn't required in this instance.
DEMO: http://jsfiddle.net/TDBzN/6/;
h1
{
clear:both;
}
To create a clear:both; div put this in between the h1 element and the floated element, in this case that is .category.
<div style="clear: both;"></div>
This is helpful just to insert where you need an element clearing and it isn't appropiate to clear the element directly.

Answer 2

Put clear left on your heading should work
#article h1 {
font-size: 33px;
color:#555;
font-style:italic;
clear:left;
}
See http://jsfiddle.net/TDBzN/2/

Answer 3

DEMO
Edit the class .category from:
.category {
float: left; /* REMOVE */
text-align: center;
font-size: 12px;
color: white;
padding: 8px 18px;
margin: 18px 0 0 0px;
text-decoration: none;
-webkit-transition: background 0.3s ease;
-moz-transition: background 0.3s ease;
-ms-transition: background 0.3s ease;
-o-transition: background 0.3s ease;
transition: background 0.3s ease;
background: rgba(71, 186, 255, 0.8);
}
TO
.category {
max-width:70px; /* EDITED */
text-align: center;
font-size: 12px;
color: white;
padding: 8px 18px;
margin: 18px 0 0 0px;
text-decoration: none;
-webkit-transition: background 0.3s ease;
-moz-transition: background 0.3s ease;
-ms-transition: background 0.3s ease;
-o-transition: background 0.3s ease;
transition: background 0.3s ease;
background: rgba(71, 186, 255, 0.8);
}
and it work fine.
