Canvas from html5 was introduced some time ago. Currently it's used (almost) only for demonstrations how cool it is - it's mainly related to painting, games and charts. Many of them can be found at Canvas demos. How creatively / unusually can canvas be used? Some examples: jsAscii - ASCII art from images with Javascript and Canvas (...

Hi stackoverflow experts I've been experimenting with the audio and local storage features of html5 of late and have run into something that has me stumped. I'd like to be able to cache or store the source of the audio element locally to enable speedier and offline playback. The problem is I can't see how this is possible with the cur...

I'm having trouble roating an image around itself using Canvas. Since you can't rotate an image you have to rotate the canvas: if I rotate the canvas by a degree the origin around which I want to rotate changes. I don't get how to track this change. This is my current code: http://pastie.org/669023 And a demo is at http://preview.netl...
HTML 5 is the new W3C definition for HTML and will likely represent the direction the internet goes as people find the next killer apps that work in it. There are the much publicized 'public' coding features like the <video> tag, but I'm wondering what low-level coding tricks people have found so far that could be important, useful, int...

I am taking a peek at Dive Into HTML5. It seems nice and interesting, but I am puzzled. In the 1990s, at the time when Netscape was the browser and HTML was HTML2 or HTML3, there were a lot of tags: address, cite, code... Most of them are unused as of today, probably even obsolete. HTML5 introduces tags to express "semantic meaning" t...

I'm then using a jQuery.date-input plugin to override this behaviour on browsers that don't support it. Problem is - the jQuery's running on Opera a...
From reading the mailing lists and looking at the specification I cannot tell what the limits of HTML5 are as a software or programmatic technology. I have seen where they have attempted to standardize video and audio formats in HTML5 and it seems they may be writing the definitions for XHTML5 into the HTML5 specification. It also appe...
Is there a nice tidy jQuery plugin that allows including a single JS script then using a simple snippet to enable a form? Something like this: $j('#MyForm').enableDragDropUploads('.upload-area') With the upload target being the action of the form. Any solution must not prevent a regular file field from being usable (using traditional...

In CSS and HTML world there are always features (Properties/Attribute/Tags) that would be useful in fringe scenarios, but for that very reason most people don't know them. I am asking for features that are not typically taught by the text books about CSS, CSS3 and HTML5. What are the ones that you know? [UPDATE] Which browsers adopt HT...
Since Visual Studio 2010 is slated for release in March of 2010 and HTML 5 is now starting to be used even more widely, I would like to know if Visual Studio will ship with HTML 5 templates, standard controls and support for the more common markup?
