title: How do you tell what CSS settings are affecting the layout?
body: <p>I have a project with several CSS files, each with many different settings. Every now and then I'll put an element on the page and it will appear unexpectedly, like an odd indentation, font color, hover behavior, etc. It's always a hunt to figure out exactly what CSS setting is causing the behavior. Is there any way to know exactly which CSS values are being applied to a given element?</p>
