How do you use Chrome Extensions to change CSS of a web site?

Question

I\'m looking to create an extension for personal and possibly personal friend usage as well that simply changes a few colors that are displayed on a website I visit. I use Reddi

Answer 1

There are already extensions made for this. The one I use is called Stylish, which only modifies appearance using CSS3 only, and not html. There are other extensions as well, do some google searches and you will find a few more.
