Properties that are not descendants of an element with the itemscope attribute can be associated with an item using the global attribute itemref. itemref provides a list of element IDs (not itemids) elsewhere in the document, with additional properties The itemref attribute can only be specified on elements that have an itemscope attribute specified.
The current microformats include pattern offers two methods — using <object> or <a> — to include in a microformat element parts of a document that are outside of that microformats element's DOM tree. Both patterns have problems, and have not been widely adopted. Also, the include pattern has not been updated for microformats 2. This page is a proposal for a new include pattern using a custom element without any semantics.
Using the HTML field is normally a good idea when you're asking the user to enter a URL. It doesn't make a huge difference on desktop browsers, but makes it a lot easier on mobile browsers. On iOS, when you've focused on a URL input field, the keyboard switches to a slightly diffe...
Browser support tables for modern web technologies
In August 2012, I wrote a quick script to stream front-page Hackernews stories to an IRC channel on Freenode (##hackernews in case you're interested) so that I could quickly glance at popular stories there instead of needing to load Hackernews. Since IRC is my feed reader, I've always tried to pipe as much there as possible.
My favorite part here:
So in 2.5 years of parsing the HTML, I never had any problems. In 2 days of parsing the JSON API, I hit a glitch where all the stories were empty.
Since more people and programs see the HTML than use the API, the HTML ends up being more reliable.
While I occasionally do some small uploading tweaks like this, it seems like ages since I created webpages like this outside of more elaborate content management systems. Hooray for raw HTML and CSS! It’s also a bit refreshing to do it all manually in an interface instead of via FTP or other means.

I thought it was a pretty slick use of HTML to create some really simple and broadly useful UI.
Then earlier today I noticed that Jeremy Keith has recently switched to using this on his personal site in the comments section to provide toggles for his various webmention types including shares, likes, bookmarks, etc. But this is where I’m noticing a quirky UI issue that isn’t as web friendly as it could be. Jeremy and others (including myself own my own site) will often provide ID tags so that one can give permalinks to the individual comments using fragments of the form:
But here’s where the UI problem lies. The first fragment URL only resolves to the page instead of the specific bookmark hiding behind a <details> tag whereas the second fragment URL resolves to the page and automatically scrolls down to a comment by DominoPivot. It does this in both Chrome and FireFox and I would presume operates similarly in other browsers.
I suspect that most users would expect/prefer that the fragment URL should automatically expand the <details> tag and scroll down the page to that ID or fragment as well.
Perhaps Jamie, Jeremy, Tantek, Kevin or others may have some trickery to make this happen? Otherwise, do we need to start digging into specs and browsers to get them to better support this sort of fragment related functionality? Perhaps it’s this section of the HTML spec, the URL of which has such a fragment and therefor scrolls down properly if you click on it? (Meta pun intended.)
Today W3C and the WHATWG signed an agreement to collaborate on the development of a single version of the HTML and DOM specifications. The Memorandum of Understanding jointly published as the WHATWG/W3C Joint Working Mode gives the specifics of this collaboration. This is the...
Search the web for "CSS classes" and you'll find numerous well intentioned references which are imprecise at best, and misleading or incorrect at worst. There are no such things as "CSS classes". Here's why you should refer to HTML classes, CSS class selectors, or even CSS pseudo-classes, but not "C...
Some thoughts on entry points to web development today, and my fears about the loss of something that has enabled so many people without a traditional computer science background to be here.
