Tips and best practices
- Formatting mainly improves readability and maintenance; it is not intended to change how the page renders.
- Minification removes spaces and line breaks, but keep a readable source version for future edits.
- After transforming complex CSS, test the final page rendering, especially when the code contains hacks or unusual syntax.
Frequently asked questions
Does formatting change the page rendering?
The goal is to change code presentation only, without intentionally modifying CSS rules.
Why minify a stylesheet?
Minification removes characters that are not required for CSS interpretation in order to produce a smaller file.
Should I keep an unminified version?
Yes. A readable source is usually better for maintenance, debugging, and collaboration.
Is my CSS uploaded to a server?
No. Formatting and minification run locally in your browser.
