By Matt DeClaire on Mar 20, 2008 in Web Engineering Back when I was in school a teacher instilled in me a strict eye for code style. We submitted our assignments electronically to a testing script on his account, but before an assignment began running the rigorous gamut of test cases, it had to first pass a style check.
The style check was quite a trial in and of itself. It usually took several iterations of submissions just to get the code’s style in order. Every student came out of that class with pristine code “handwriting.” The advantage to clean code style is readability. The specifics of the rules used in a style guide are not as important as consistency. Variable Names Variables should be camelcase, with a lowercase first letter — examples: articleDate, userDetails, spoonThe name should refect the semantics of the element, rather than the style — examples: tinyFont (bad), imageCaption (good) CSS Rules Organization reset Use a variation (if not exact) of Eric Meyer’s CSS Reset shell Hey!
7 Principles Of Clean And Optimized CSS Code | CSS | Smashing Ma. Advertisement Some of you may remember the days when 30KB was the recommended maximum size of a web page, a value which included HTML, CSS, JavaScript, Flash, and images. I find with every new project with even the slightest bit of complexity, it’s not long before that 30 KB ideal is well out of my reach. With the popularity of CSS layouts and JavaScript-enriched web page experiences, it’s not uncommon, particularly for large sites, for the CSS files alone to jump well beyond that 30KB ceiling.
But there are some principles to consider during and after you write your CSS to help keep it tight and optimized. Optimization isn’t just minimizing file size — it’s also about being organized, clutter-free, and efficient. You’ll find that the more knowledge you have about optimal CSS practices, smaller file size will inevitably come as an direct result of their implementation.

Big CSS files can be complex to manage but a good structured code can help you to make your life simpler. This is a descriptive post about how to write a well structured CSS file.

I experienced, proceeding without "order" or a clear vision about what you want to realize can be harmful and you risk to add, change, remove classes and properties, with the only result to have untidy code with a lot of unused elements on your final product.
