As your traffic increases, whether you run a website or a blog, it becomes very important that your files use minimum bandwidth and this is true for your CSS files too. That’s why it is consistently advised you should optimize your source code for every file and if possible, you should create shorter CSS files. There is a tendency of your CSS files swelling up quickly because when you are creating your website layout using cascading style sheets you often want to re-define the look and feel of every element in your page and this means a separate CSS line for every element. But you can define multiple elements in the same line and you can use shorter names for longer ones. A post at Pitic Style tells you how to create smaller CSS files.
