I'm completely new to Zen and think I have a good grasp of it. However, I'm having problem changing the font colors on a part of the page which I believe is called a "legend". This is the part of text, such as on the signup page, which displays sections in their own boxes with a small border around them. I've searched Google numerous times as well as the forums here and my own site files, but can't seem to find what I'm looking for. I didn't find a place to change it in the CSS either(I found a legend section in the CSS, but specifying a color had no effect on it). Below I am pasting a sample of what I'm referring to:

<fieldset>
<legend>Per Item&nbsp;</legend>
<div class="important forward">$2.00</div>
<input type="radio" name="shipping" value="item_item" checked="checked" id="ship-item-item" /><label for="ship-item-item" class="checkboxLabel" >Best Way</label>
<!--</div>-->
<br class="clearBoth" />
</fieldset>

Any help will be greatly appreciated -- thanks in advance!!!
