grunt-contrib-csslint

2.0.0 verified Fri May 01 auth: no javascript deprecated

Grunt plugin to lint CSS files using CSSLint. Version 2.0.0 is the latest stable release, compatible with Node.js >=0.10.0. This plugin integrates CSSLint into Grunt, allowing configuration of CSSLint rules directly in the Gruntfile. It supports custom rule sets and reports warnings and errors. Compared to other CSS linters, it leverages the CSSLint library and is designed for Grunt-based workflows. It has been maintained as part of the grunt-contrib series, but note that CSSLint itself is no longer actively maintained.
