I am trying to do some dynamic visual effects using the HTML 5 canvas' pixel manipulation, but I am running into a problem where setting pixels in the CanvasPixelArray is ridiculously slow. For example if I have code like: imageData = ctx.getImageData(0, 0, 500, 500); for (var i = 0; i < imageData.length; i += 4){ imageData.data[i...
Everyone, every blog is talking about HTML 5 and giving solution to use HTML in all browsers including IE6. Should we leave XHTML 1.0 now and go for HTML 5 and use JavaScript for IE6 support?

I'm trying to make a HTML5 webapp that simply plays a sound over and over and over again, on my iPhone. I don't know any Obj-C to do it natively.

I'm starting a side project and want to build it with HTML5+CSS3. Backward compatibility isn't a concern. I wonder if exist a framework similar to BluePrint/960gs.

Hi, I'm using the HTML5 elements and in a project i'm working on (see it here) and the css seems to be working fine in Chrome. However, it doesn't appear to be working in Safari or Firefox (I haven't tested IE, but I'd imagine it's the same), and the page layout is all over the place. Any ideas why this may be? I know Firefox and S...

It seems to be tailored towards inline navigational unordered lists, completely overwriting the height and width set for the articles (and or the sections) in the CSS. Here is the html: <div id="container"> <section id="about" cl...
Say I had a file like... http://my.website.com/myfile.raw and this file was just raw bytes, representing an intensity image. Is it possible to grab this data and read the bytes in JavaScript?
