Stylish is a style management extension for Firefox. In simpler words, Stylish is to CSS what Greasemonkey is to JavaScript. It lets you customize boring sites with your own styles. Before I continue with this post, have a look at what Stylish can do to Google:

Installation:
Install Stylish, just like any other extension for Firefox. Once it’s installed, grab some CSS cheats from Userstyles.org and load them into Stylish. [The above screenshots uses Dark Blue and Gray/Black by Valacar]
While browsing style repository on Userstyles.org, I found tons of sleek style. Here’s a list of few of my favorites:
- Dark Blue for Google
- Gray/Black for Google
- Black Orkut, No Ads
- Gray/Black for YouTube
- Del.icio.us at Night
- Digg Stripped to the Bones
Note: Dark Blue and Gray/Black for Google won’t work with localized version of Google. Dark Blue for Google.co.in is available, others can make their own styles by replacing “google.co.in” with “google.xx.xx” in Dark Blue for Google.co.in

That is pretty cool. I would use that extension except I have personalized Google and I heard it doesn’t look nearly as good. I really like that black design though.

[...] I personally welcome the new design to be implemented on the main site, as I’m quite bored of the old one. Has anybody tried Stylish to turn Google black? [...]
