You'll notice that CanIUse has a "% of all" option right above the Global percentage. If you dig into the gear wheel on a feature you'll see more information about this:<p>Usage calculation:<p>( ) All Users: Any usage % of browsers not tracked by caniuse is considered unsupported.<p>( ) All tracked users: Excludes the usage percentage of browsers not tracked on caniuse.<p>This implies that CanIUse pulls in data about global browser usage, but does not cover all of the browsers mentioned in that usage data. By default it just assumes that browsers that it doesn't track any data on are not supported. If you change this to All Tracked Users you then get 98.71%.<p>The sum total of the browsers listed in the chart which have unknown support (these are different than the browsers being referred to in the setting above) is 1.27%. Worth it to note that likely there's some rounding going on here, as when you take 98.71% and add in that 1.27% you get 99.97999..%<p>Pretty close though.<p>So the real issue is indeed that those browsers show Unknown, when I think we can safely say they do in fact support the html element.
> MDN used to stand for Mozilla Developer Network. Now it’s just MDN. I spent a few minutes looking on the MDN site to see if I could find any mention of the full name, but I guess they’re just all in on “MDN” now.<p>Huh, yeah, nerd-sniped on that one; I can't find anything either.
Interestingly, it was also pointed out to me that the `a` and `p` elements have exactly the same 97.34% support. Both of these elements have data coming from MDN like the `html` element. See: <a href="https://caniuse.com/mdn-html_elements_a" rel="nofollow">https://caniuse.com/mdn-html_elements_a</a> and <a href="https://caniuse.com/mdn-html_elements_p" rel="nofollow">https://caniuse.com/mdn-html_elements_p</a><p>I've updated the article to note this.
The original webpage doesn’t use the html element.<p><a href="http://info.cern.ch/hypertext/WWW/TheProject.html" rel="nofollow">http://info.cern.ch/hypertext/WWW/TheProject.html</a>
> a lot of the data on the site actually comes from MDN<p>Eh... not really.<p>The feature support matrix (as linked on CanIUse) comes from MDN's browser-compat-data repo. Here's the HTML element's source data: <a href="https://github.com/mdn/browser-compat-data/blob/main/html/elements/html.json">https://github.com/mdn/browser-compat-data/blob/main/html/el...</a><p>This doesn't contain the testing and usage info that CanIUse cites for support, though, just which browser versions included which features.<p>CanIUse also points to their own repo, which contains a lot of data: <a href="https://github.com/fyrd/caniuse">https://github.com/fyrd/caniuse</a><p>But I can't find an easy entry point to find where they're getting the numbers for a specific element. The data on there seems to be primarily for features.<p>So the more precise question is, where is CanIUse getting HTML element testing and usage numbers from? Because that seems to be the issue.
What would it mean to NOT "support" <html> -element?<p>Is putting <html> on a page supposed to somehow alter the way the page is presented?
