Hunter's comment

CSSO (CSS Optimizer) is a CSS minifier. It performs three sort of transformations: cleaning (removing redundant), compression (replacement for shorter form) and restructuring (merge of declarations, rulesets and so on). source

CSSO is a CSS optimizer that you can use to minify your CSS code so that your website can load faster and lightweight.

It also cleans your codes and removes anything that could slow down your web project.

Click the Try It Out button to use this CSS editor to minify, clean and set rules for your project.
