I my encounter, I haven't encounter a circumstance the place making use of is problematic, even so, there are numerous situations exactly where or Particularly might be problematic in more mature browsers and equipment.
Edit: Since we are all mad about specs, I believe it truly worth declaring that according to dev.w3.org:
Can you cite a reference to the non-XML syntax currently being desired in HTML5? Which is information to me. Optional assistance for rigorous XML conformance was a founding aim of HTML5 as I remember.
and don't meet up with the necessities of XML and XHTML mainly because they would not have closing tags, eg: or are legitimate, just isn't legitimate XHTML or XML. HTML, naturally, does not have the nicely-fashioned requirement so and are legitimate in HTML only.
I am aware this is a very aged reply, but by now browsers that misinterpret are nearly extinct. They were being previously pretty uncommon by the time the answer was posted.
We could only hope that Later on World Wide Web, we shift from non-public vendor-carried out specifications and return to strong, reliable, verified markup that parses faster, moves knowledge more than the wires speedier, and make our potential Internet a far more standardized medium making use of XML.
HTML five.two will make the venerable plugin system out of date. The internet was when extended by plugins - downloaded code with terrific electric power about the person's Pc. New systems or abilities like virtual fact or speech conversation at the moment are developed as Component of the Web Platform.
@jmarkmurphy, I believe probably that you are unfamiliar While using the phrase "nicely-shaped" becoming a technological jargon phrase to consult with the requirement to your html 5 specifications of XML and XHTML that every one tags should have closing tags and needs to be nested in the proper purchase.
Aged Netscape often desired the " /" Area prior to the slash or it failed. Who cares about outdated browsers, ideal? But its one more situation for my Edition I continue to like :)
Just after looking at this self-closing tag posting and checking code in console myself I arrived to are aware that in HTML5 Even though you create or they'll ultimately be transformed to through the browser.
and so are correctly legitimate and very well shaped HTML. They're not valid XML tags. The HTML specs under HTML syntax says that void components (like or ) might have a / character right away previous the final >.
You shouldn't provide it by having an XML declaration if applying textual content/html, even so the articles could be or else legitimate XML (e.g. generated from something which outputs XML, like XSLT output or an item that serializes to XML).
The other types are there for compatibility with XHTML; to make it attainable to write down precisely the same code as XHTML, and also have Furthermore, it work as HTML.
