In plain English

HTMLHint is a tool that checks your HTML code for mistakes and bad practices before they cause problems in your browser. Think of it as a spellchecker for your web pages, it scans your HTML files and flags issues like missing closing tags, duplicate attributes, or other sloppy code that could break how your page displays or behaves. You can run it in a couple of ways. It plugs into code editors (IDEs) so you get warnings as you type, similar to how a word processor underlines spelling errors in real time. You can also integrate it into your build system, which means it runs automatically as part of your development workflow, for example, before code gets deployed to a live website. The tool comes with a set of rules it checks against, and you can configure which ones matter to you. This is useful for anyone writing HTML, from solo developers working on a personal site to teams building production web applications. If you've ever spent an hour debugging a broken layout only to find a missing closing tag, this tool catches those errors for you instantly. It's especially valuable for teams that want to enforce consistent code quality standards across multiple contributors. The project is written in JavaScript and has been around since 2013, released under the permissive MIT license. The README is fairly minimal, it points to separate wiki pages for usage instructions, the full list of rules, and a developer guide, rather than including that documentation inline. The tool has strong test coverage at 98%, which suggests the project is maintained with care and is reliable to depend on.

Copy-paste prompts

Prompt 1

I want to add HTMLHint to my VS Code editor so I get warnings about bad HTML as I type. Walk me through installing and configuring it step by step.

Prompt 2

Help me set up HTMLHint to run automatically in my build pipeline before code gets deployed, so bad HTML never reaches production.

Prompt 3

Show me how to create an .htmlhintrc config file that turns on only the HTMLHint rules I care about and turns off the ones I do not need.

Prompt 4

I have an existing HTML project with sloppy code. Help me run HTMLHint on the whole project and fix the most critical errors it finds.
