If you want to speed up development using CSS stylesheets, you have to break the habit of refreshing the page with either refresh or control-f5.

Reload your CSS with ReCSS.

All you have to do to add this wonderful tool is drag, add or bookmark the javascript link. Next time you have to do CSS edits, you don’t have to refresh the page. Just click the bookmarked ReCSS and viola!

Enjoy!
