HTML Inspector Helps You Write Better Markup
HTML Inspector traverses the DOM and emits events as it goes. The HTML Inspector rules can then listen for those events, test for certain conditions, and report errors when something unexpected is found. HTML Inspector comes with a set of built-in rules, but if you need more, you can easily write your own.
Like JSHint and CSSLint, HTML Inspector is completely customizable, so you can use what you like and ignore what you don’t. It’s also extensible and pluggable, making it possible to write your own rules that enforce your chosen conventions.
