CSSLint is an open source CSS code quality tool originally written by
Nicholas C. Zakas and
Nicole Sullivan. It was released in June 2011 at
the Velocity conference.
A lint tool performs
static analysis of source
code and flags patterns that might be errors or otherwise cause problems for the
CSSLint is a tool to help point out problems with your CSS code. It does basic
syntax checking as well as applying a set of rules to the code that look for
problematic patterns or signs of inefficiency. The rules are all pluggable, so
you can easily write your own or omit ones you don't want.
All about the command line interface for CSSLint. If you'd rather use a CLI
program to verify your CSS instead of using the web site, then this guide is
your best friend.
Once you're familiar with the CSSLint command line interface, the next step is
to integrate it into your build system. This guide walks through using CSSLint
as part of your build.
You can integrate CSSLint into your favorite IDE to make checking your CSS code
quality easy. In fact, some IDEs already have CSSLint built in.
Not sure why a rule is important? This guide talks about each of the CSSLint
rules and explains how the rule is designed to improve your CSS.
If you want to contribute to the project, or even just tinker on your own,
this guide explains how to get the source and work with it.
