HTML5: The Difference Between , and

Posted 2 hours, 48 minutes ago at 2:15 pm. 0 comments

If you’re confused as I was about when to use vs. when coding an HTML5 document, this article by Oli Studholme will help clear things up.

To decide which of these three elements is appropriate, first think if the enclosed content would make sense on it’s own in a feed reader—if so use . If that’s not the case, is the enclosed content related? If so use . Finally if there’s no semantic meaning use
. Except for occasional use to provide a hook for styles, I expect the humble
will mostly be superseded by , and where required more specialised HTML5 elements.

HTML Minification

Posted 4 hours, 49 minutes ago at 12:14 pm. 0 comments

Good old Kangax has been playing with HTML minification and has shared his new tool in an early stage.

What does it do?

Kangax has forked John Resig’s HTML parser which parses the HTML and sends that into the Minifier. This has rules that do things like whitespace optimization, comment removal, and collapsing boolean attributes (e.g. disabled=”true” -> disabled).

He also has a linter going:

While working on minifier, I realized that oftentimes the most wasteful part of the markup is not white space, comments or boolean attributes, but inline styles, scripts, presentational or deprecated elements and attributes. None of these can be simply stripped, as that could affect state of the document and is just too obtrusive. What can be done, however, is reporting of these occurences to the user. HTMLLint is even a smaller script, whose job is exactly that—to log any deprecated or presentational elements/attributes encountered during parsing. Additionally, it detects event attributes (e.g. onclick, onmouseover, etc.). The rationale for this is that moving contents of event attributes to external script allows to take advantage of resource caching.

Harmony: Canvas Drawing Tool

Posted 6 hours, 13 minutes ago at 10:50 am. 0 comments

Harmony is a new drawing tool, a HTML5/Canvas experiment with great potential. It provides some unique brush styles, and can produce some great-looking charcoal pencil style sketches, among other things. Better to try it out than explain it in words.

Creator Mr. Doob (Richard Cabello) explains how he used Canvas to make it darker the more you draw over it:

The whole thing is quite modular so I can keep adding more brush styles whenever I get inspired. During the process I found out that, for some reason (apparently lack of hardware acceleration), Firefox and Opera do not support context.globalCompositeOperation = ‘darker’. This was on the HTML5 spec before but got removed. Just so you know what I’m talking about, this is like the “multiply” blending in Photoshop. Webkit does support it tho. I hope they put it back on the specs and all browsers support it.

You can also save images using data URI encoding.

As it works on webkit, he made sure it worked on the mobile Android and iPhone browsers. No multi-touch as yet, but the touch UI still makes a nice input mechanism.
