Xyle Scope is a very cool piece of software. It is a browser for analyzing websites, particularly those built with a heavy reliance on CSS. It offers three views:

• Web browser – based on WebKit.
• Hierarchical navigator – a column view widget for browsing the HTML hierarchy.
• HTML pane – showing a properly formed view of the HTML
• CSS pane – shows the css styles that apply to the selected element in any of the other views.

Xyle Scope is very sweet. I’m sending in my box tops now.
