htmlhint/HTMLHint

HTMLHint is a static code analysis tool for HTML that identifies and reports quality issues in markup files.

The tool solves the problem of maintaining consistent HTML quality and catching common mistakes by analyzing HTML files against a configurable set of rules. It works by parsing HTML and checking it against these rules, then reporting violations with their locations and severity. The tool can be run on individual files, directories, or even remote URLs, and supports both command-line and programmatic usage.

Developers should choose HTMLHint if they want to enforce HTML standards and best practices across their projects. It suits teams working on web applications who need automated quality checks as part of their build or development workflow. The tool can be installed locally within a project or globally for use across multiple projects. Configuration is flexible, supporting a `.htmlhintrc` file that the tool searches for in the current directory and parent directories, custom configuration files, custom rules, and inline rule directives within HTML files themselves.

The project maintains active development with regular updates and contributions from multiple developers. The codebase is written in JavaScript and requires Node.js for execution. The project has established governance through a contributing guide and maintains an organized documentation site covering getting started, available rules, and development procedures.
