I think it will work if you change the line like this:
Code:
<h3 class=h3.analysis>Figure 3.</h3>
Or just write:
Code:
<h3>TEXT</h3>
And add this in the CSS to change the defaults for the H3 tag.
Code:
h3{
font-family: "Verdana", sans-serif;
font-size: 24px;
font-weight: bold;
color: #FFFFFF;
margin: 10px;
}
(the margin: 10px make the same spacings in IE and FF)
