CSS is a style sheet language that is used to control the overall look and style of a website.  When website developers program CSS, they often leave lines in between the codes for better viewing.  This makes the code easier to read and modify.  However, the more spaces and lines a CSS file contains, the longer it takes for the page to load.

Under Page Speed, there is an option called “Minify CSS”.  It provides optimized versions of your website’s CSS files.  This option helps website owners to delete the unnecessary lines and spaces in order to boost their web pages’ loading speed.

The problem with minifying your CCS files is that they will be hard to read and hard to edit.  To solve this problem, we recommend the following.

  1. Back up your original CSS file by downloading it from your website.
  2. Download the optimized version of CSS from Page Speed.
  3. Replace the original CSS file on your website with the optimized one.

In terms of functionality, your optimized CSS file is identical to the original one.  By doing the above, your page speed will significantly increase.

In case you need to modify your website style, you can make changes in the original CSS file saved on your computer and then upload it to your website.  You can then use Page Speed to optimize your CSS file again and use the optimized one for faster loading.
