## What it is
CSSLint is an open source CSS code quality tool that performs static analysis of stylesheets, flagging syntax errors and problematic or inefficient patterns. It offers a pluggable rule system and can be used via CLI, build systems, or IDE integration.

## Use cases
- lint css files for errors
- check css code quality
- find inefficient css patterns
- integrate css linting into build pipeline
- enforce css style rules in ci

## When to choose
- you need automated CSS static analysis with pluggable rules
- you want a CLI or build-system CSS linter for legacy or simple setups

## When to avoid
- you need modern CSS syntax support or actively maintained rule sets like stylelint
- you need autofixing of lint errors

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: linter, static-site-generator
- domain: web-development, frontend, developer-tools
- platform: cli, cross-platform
- tags: css, code-quality, static-analysis, pluggable-rules, nodejs
