well, if you look @ it with firebug (FF add on), it's clear that you are overriding the b tag to be brown.

what are you doing loading default.css and loading it 2 times ?

just unstyle that tag or add a style for the b tag in your extra css, if you need this 'default.css' to be loaded ..

Code
<b>
<span id="subject0">About Logging In</span>
</b>

note that it's contained withing <b> tag wink
