DownloadSquad told us about a great new tool yesterday called CSSFly. It’s not a Firefox addon, or additional software, it’s an XHTML based tool that allows you to see and edit the source code of any website at a push of a bookmarklet.
CSSFly creates a frame at the top of your browser where you can see the source HTML or source CSS file and you are allowed to make edits. The edits then update in real time. Great for troubleshooting web design issues or digging though someone else’s source to figure out how they archived a certain technique.
Best of all, it’s free. My initial thoughts and tests are very positive. However I’d like to see Safari support and source code coloring if possible. Those are minor though. It’s a very cool tool and one that I’ll keep handy.
