I made some changes in the CSS Editor but they arent showing up, whats going on?

This is a very common problem. Most browsers cache all css files that they get to speed up future page loads. Due to this your changes are not applied because your browser is caching the old css. There are two ways around this. You can turn off your cache entirely in your browser's settings, or you can clear your cache whenever you think that one of your changes is not being accurately reflected by your browser.
