If your website takes longer to load, the essential thing to increase the website speed is to minimize your resources. Using the CSS minifier, you can reduce the stylesheets' file size and increase the loading speed. The compressor tool removes all empty spaces, comments and redundant code, so fewer bytes are sent to the client.
Another step to increase the speed of your website is to bundle the resources. The bundling process consists of concatenating all your files that have the same type. For example, if your site has three CSS resources, then three requests are made by the client but if you concatenate these files, then only one request is made.
After you minify your stylesheets and bundle them together, your website speed can increase 100% or more.
This CSS minifier is based on Nuglify library.
