More About HTML Validator

HTML Validator is an extension to validate the HTML code of the current web page. Have it run automatically, click the icon for a menu or press any of the keyboard shortcuts (see below) to validate the current web page.

You can choose to get the validation results directly inline in the current web page or open them in a new tab with the W3C validator results, both for public URLs and local HTML (i.e.code in a page that is not globally accessible on the Internet).

For inline validation, the extension badge will show the number of validation errors once validation is complete. This works automatically for both locally and publically available content.

Keyboard shortcuts:

Press Ctrl + Shift + V to validate a page
Press Ctrl + Shift + A to validate a local page

Press Cmd + Shift + V to validate a page
Press Cmd + Shift + A to validate a local page

Press Esc to hide the list of validation errors.
