Tip: CSSEdit + WebKit Nightly
Is it possible to use a newer version of WebKit with CSSEdit? Yes, and it’s easy! Here’s what you need to do:
1) Download the latest WebKit from nightly.webkit.org.
2) Install the WebKit application somewhere, in Applications for example.
3) Run the following Terminal command (replace /Path/to with the appropriate locations):
env DYLD_FRAMEWORK_PATH=/Path/to/WebKit.app/Contents/Resources WEBKIT_UNSET_DYLD_FRAMEWORK_PATH=YES /Path/to/CSSEdit.app/Contents/MacOS/CSSEdit
4) That’s it! You’re now able to design your style sheets with the latest WebKit CSS improvements.

Great tip, but how can i switch back to the normal behaviour?
Is it:
env DYLD_FRAMEWORK_PATH=/Path/to/Safari.app/Contents/Resources WEBKIT_UNSET_DYLD_FRAMEWORK_PATH=YES /Path/to/CSSEdit.app/Contents/MacOS/CSSEdit

Rolf, this tip will only make CSSEdit use the WebKit Nightly during that session. It’s not persistent, so you’ll need to execute it every time.

Thanks for clearing that up Jan. This way it is very easy to switch between versions of Webkit.

Thanks for the tip! : ) It’d be great to have this as a preference from within CSSEdit. WebKit usually resides in /Applications anyway.

SvT, as mentioned before: CSSEdit is Mac-only and will stay that way.

I tried this and got the following
