Node.js Version Support

Clean-CSS CLI requires Node.js version 10.0 or higher. It has been tested on Linux systems.

Installation

To install Clean-CSS CLI globally, use the following command:

npm install clean-css-cli -g

Note: The global install option (-g) is recommended to make the command accessible without needing relative paths.

Usage

To optimize a CSS file, you would run:

cleancss -o one.min.css one.css

This command takes “one.css” and outputs the optimized version as “one.min.css”.

Now, let’s delve into Clean-CSS CLI’s features with an analogy for better understanding. Think of optimizing CSS like cleaning out your cluttered closet. Each item (CSS rule) takes up space and contributes to the overall chaos (file size and render time). Just like you would sort through clothes based on whether you wear them or they fit your style (removing unnecessary styles and unused properties), Clean-CSS helps you eliminate redundancies, allowing for a neat, organized, and efficient wardrobe (CSS file).

Troubleshooting

Here are some common issues users face and their solutions:

• Issue: I get an error saying “command not found”.
  Ensure that Clean-CSS CLI has been installed globally and that your PATH environment variable is set correctly.
• Issue: My output file is empty.
  Make sure that the input CSS file is not empty and check that the path is correct.
• Issue: Optimization seems to remove vital styles.
  Review the optimization levels you are applying. Consider using `-O0` to skip optimizations temporarily to identify problematic rules.
• Issue: The inline styles are not working as expected.
  Double-check your `–inline` settings and ensure they are correctly specified.
