CSS HTML Validator for Apple Mac (htmlval)

Use the command line (console) tool htmlval for Mac/macOS to check HTML, CSS, and JSON documents on macOS, and try using it with your favorite Mac editor (see integration with Mac editors).

htmlval is based on the core validation engine in CSS HTML Validator for Windows, which has been ported to macOS.

Note that some features like link checking, spell checking, PHP syntax checking, JavaScript checking, and some other features are currently not available in the macOS port. This is a command line (console) tool for macOS; there is no GUI like in the Windows version.
