## What it is
doiuse is a CSS linter that checks stylesheets for browser compatibility issues against the Can I Use database. It works as a CLI tool, a PostCSS plugin, and integrates with build tools like Gulp.

## Use cases
- lint css for browser support
- check if css features work in ie
- find unsupported css properties for target browsers
- detect css compatibility issues against caniuse data
- run browser support checks in a build pipeline
- lint css for old browser versions

## When to choose
- you need to support legacy browsers like IE and want automated CSS compatibility checks
- you want a PostCSS or Gulp-integrated linter for browser support
- you prefer checking against the caniuse database with configurable browser targets

## When to avoid
- you only target evergreen browsers and don't need compatibility linting
- you want autoprefixing or transforms rather than linting - use autoprefixer instead
- you need full stylelint rule ecosystems beyond browser support checks
