CSS minification is the process of compressing and optimizing Cascading Style Sheets (CSS) files by removing unnecessary characters, comments, spaces, and line breaks while preserving their functionality.
This effectively reduces the file sizes and thus enhances web page loading speed, as smaller CSS files are quicker to download. Minification aims to streamline the code without altering its intended styling, ensuring a more efficient web content delivery to users.
This practice aligns with optimizing web performance, positively impacting user engagement and search engine rankings. In essence, CSS minification plays a crucial role in enhancing the efficiency of web page delivery, ultimately contributing to a more seamless and enjoyable browsing experience.
In addition to reducing the file size, minification makes the CSS a bit harder to read or to be reverse-engineered or copied by other developers.
This tool minifies the CSS code by removing the comments, extra spaces (eg. white spaces, indentations, spaces around curly braces, spaces around colons, spaces around semi-colons, etc) line breaks, units for zero values, empty CSS declarations, and the last semi-colon of a style declaration.
The minifier takes in well-formed CSS code that you have written, minifies it, and gives a minified output. There are three ways in which you can minify your CSS using this tool:
Regardless of your method, an output field with the minified code will appear below. Click on the "Copy" or "Download File" buttons to save the minified code.
It's important to keep a backup of the original file with the well-formatted CSS code. We also recommend testing the minified code before deploying it in a production environment.
