Skinning Gmailwith a Custom Stylesheet

Skinning Gmail with a Custom Stylesheet
Short Version

* Install the URLid Mozilla/Firefox extension.
* Download this CSS file.
* Locate your profile folder and the chrome folder within that.
* Copy the downloaded CSS file to the chrome folder and rename it to userContent.css (if you already have such a file, you will have to merge the two).
* Restart Firefox.
* Visit Gmail.

Je vais essayer, ça ne sert pas à grand chose mais le fait de forcer l’application d’un CSS indépendamment d’un site, c’est pas mal.
