How to Minify Your CSS

Minifying your CSS is a great and really easy option for optimizing the speed of your site. When you minify your CSS, you’re basically compressing the files so that they’re smaller and easier for your server to grab quickly. Having minified CSS files (and JavaScript files too!) can go a long way in making your site more efficient. Another benefit of minifying your CSS code is that it makes the code a lot less legible than if it were in typical standard CSS format. This way, it’s that much more difficult for other developers to steal or replicate your custom code.

If you’ve never heard of file minifying before and are skeptical about or intimidated by the process — don’t be. There are dozens upon dozens of free services available that will minify your CSS files for you in minutes — all you have to do is copy and paste the code of your CSS file into a textarea and press submit, and the minified code will be generated for you.
