A test with a simple HTML page over a DSL connection shows that one big stylesheet or css of 50 KB can speed up load time by factor 2 compared to five stylesheets that are 10 KB each in size:

• 5 Stylesheets (10KB each): 1100ms
• 1 Stylesheet (50KB): 500ms

So , How to make them one without breaking or editing them ? I am going to show you how to do this .
