CSS minification removes unnecessary source formatting for deployment-oriented output

Stylesheets often contain indentation, comments and spacing that help developers read the source but are not needed by the browser to apply normal CSS rules.

Minification is best performed on a maintained source copy rather than used as the only version of a stylesheet, because compact output is harder to debug and edit manually.

Useful CSS-minification workflows

  • Prepare a smaller deployment copy of a stylesheet.
  • Compare readable source with compact production output.
  • Reduce formatting overhead in controlled frontend assets.

Before deploying

  • Keep the original unminified stylesheet.
  • Test important pages after minification.
  • Be cautious with unusual syntax, generated CSS and intentionally preserved comments.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
