csslint

Lint CSS code. More information: https://github.com/CSSLint/csslint/wiki/Command-line-interface.

• Lint a single CSS file:

csslint {{file.css}}

• Lint multiple CSS files:

csslint {{file1.css file2.css ...}}

• List all possible style rules:

csslint --list-rules

• Treat certain rules as errors (which results in a non-zero exit code):

csslint --errors={{errors,universal-selector,imports}} {{file.css}}

• Treat certain rules as warnings:

csslint --warnings={{box-sizing,selector-max,floats}} {{file.css}}

• Ignore specific rules:

csslint --ignore={{ids,rules-count,shorthand}} {{file.css}}
