Re: Validating HTML

There are some services that do HTML validation (I didn't know about this). This relates to the topic of best practices. But, I think that a validator can't determine everything for you. For example I doubt it would distinguish an error between using an em or strong tag.

So I dug around and I've found a few things that I'm going to experiment with. I haven't had time to try them all yet:

HTMLHint for VS Code will show problems in the problem panel.
w3c validator is extension for VS Code that is probably better than HTMLHint. It requires installing Java if you don't have it.
w3c-validator command line tool in python (looks outdated...maybe). The script just uploads html to w3c validator and then parses the json response.
validator.nu which has a command line script on the about page (also in python).
