1) Make a table of contents
At the top of your CSS document, write out a table of contents. For example, you could outline the different areas that your CSS document is styling (header, main, footer etc). Then, use a large, obvious section break to separate the areas. Not only does this make your CSS look neater, but when it comes to making quick adjustments to certain areas of your website at a later date, finding the corresponding area in your CSS will be much easier.
