Change the font size of Safari's Web Inspector Does anyone know how to change the font size in Safari's Web Inspector? It's too small for me and my eyes can't stand staring at it during long periods of time. 

I've found some links on the web concerning my question but they don't seem to work either:

I'll switch back to Chrome and use its own Web Inspector if there aren't any solutions available.
Thanks for the answers above. As an update, in Mavericks 10.9, the file is still Main.css and can now be found at the following path:
/System/Library/PrivateFrameworks/WebInspectorUI.framework/Versions/A/Resources

You may also find the file using following terminal command:
find /System/Library/PrivateFrameworks -name Main.css
