Writing clean CSS is essential for readability and helps in maintaining the code. In order to write clean CSS here are few of the rules you must keep in mind.
- Use a hyphen (‘-’), underscore ('_') or camel case into class names. It is important that you maintain consistency and use any single standard for class writing in your project.
- It is advisable to use all small letters in class names if you are following the hyphen or underscore standard. It is recommended to use short and content specific class names.

- Add comments for every new section and also avoid ID selectors.
- Try to use minify CSS on the server level, when you making your website/application live.
- Avoid “!important” property
- Use external CSS
