In the forum someone gave you a piece of CSS code ?
You have played with one of the tools previously mentioned, and you want to save your changes ?

Now just copy/past your CSS code and save. The effects should be seen immediately : if not, try to refresh the cache of your browser and purge the Purge compiled templates, in [ Tools » Maintenance» ]
If you need to add comments to remember what a code do, just add two slashes before your text and the line will not be interpreted.

They are named *-rules.css with * is the name of a theme.
