Related to #320

In the webextension, sure :) I still have in mind to allow a CSS only usage, and this one is kinda special from this view.

Thanks for this! Let's ask previous translators if they could help: - @pd4d10 for Chinese translation - @bruno-machado for Portuguese Brazilian translation - @Alex-Sokolov for Russian translation - @GeorgeGkas for...

@notabene Still needs help for other languages, so I keep this issue opened and lfagged as `help wanted`.

Should I close the issue? Or maybe a simple link to #344 might do the job: on the information level, simply show heading tags. Could be useful to display them,...

Also `alt`, `title`, `tabindex`, `aria-label` and any important alternative might be displayed with CSS only.

Show `lang` and `hreflang` too.

Thanks!

More examples from @Heydon's "Apps for all": * `[role="status"]:not([aria-live="polite"])` * `[role="alert"]:not([aria-live="assertive"])` * `[aria-live="polite"]:not([role="status"])` * `[aria-live="assertive"]:not([role="alert"])` * `[role="tablist"] a:not([role="tab"])`: not quite sure about this one… * `[role="tabpanel"]:not([id])` * `[role="tab"]:not([aria-controls])`

Good point! And in fact we'll probably have errors, warnings and advices too, makes sense to stick to the current levels.
