HTML Validator Extension

This is the of HTML Validator extension for Chrome Manifest V3.
It checks the code, syntax, of your HTML 5 pages.

HTML Validator for Chrome is a browser extension that adds HTML validation inside Developer Tools of Chrome. The number of errors of a HTML page is seen with an icon in the browser status bar. The details is seen in the developer tools.

The extension is based on HTML Tidy. The algorithm was originally developed by the Web Consortium W3C. The algorithm is embedded inside your browser and makes the validation locally on your machine, without sending HTML to a third party server.

HTML Tidy is a helpful program that tries to help people to correct their HTML errors. It finds HTML errors and classifies them in 3 categories:
* errors: HTML errors that Tidy cannot fix or understand.
* warnings: HTML errors that Tidy can fix automatically
* (optional) accessibility warnings: HTML warnings for the 3 priority levels defined in W3c WAI

There is also an automatic \"Clean up\" button that will do his best to propose you a cleaned version of your page, without errors.

Carmody Staff (ID: 00000063ac2df949) Voted 4 ★ - Updated 12/22/2022 Pretty decent, but it doesn't seem to be fully HTML5 compliant. It didn't like me using "checked" instead of checked="checked", both of which are valid for HTML5.

Віталій Мосейчук (ID: 000000a97aaafd8a) Voted 1 ★ - Updated 11/10/2022 Не работает с первого раза, куча раз подгружать надо. Ужас.

Deloo (ID: 000000bff3497edb) Voted 3 ★ - Updated 04/25/2022 Does the job but doesn't update the page URL after clicking a link... makes it unusable

John Barounis (ID: 000000c1ba04f589) Voted 5 ★ - Updated 09/16/2021 Good, it is very nice that can see the source directly from the HTML validator tab in dev tools so to inspect the errors... Thanks.
