Use Find Definition with CSS Class
Simplest tip ever: Use Visual Studio's Go To Definition with CSS classes to get from your HTML to the relevant CSS rule. First click on the name of a class in your HTML:
<div class="error" …
Then press F12 (or right-mouse click and select Go To Definition) and, voila, you're in the right style sheet with your CSS class rule selected. It also works with the CssClass attribute:
<asp:Label ID="BodyContent" cssclass="error" …
