Hey All, I am looking for a list of web browsers that fully support using ContentEditable. I know that I.E has supported it since 5 or 5.5, but what about other browsers. I know that the modern versions of Chrome, Flock, Maxthon, Opera and I.E support it. But I don't care about the modern browsers. What about the older versions of them,...

I am learning ways of manipulating HTML 5 Canvas, and decided to write a simple game, scroller arcade, for better comprehension. It is still at very beginning of development, and rendering a background (a moving star field), I encountered little, yet annoying issue - some of the stars are blinking, while moving. Here's the code I used: ...

Something like this - <audio controls="controls"> <source src="song.ogg" type="audio/ogg" /> <source src="song.mp3" type="audio/mpeg" /> Your browser does not support the audio element....

If there is no DTD or schema to validate the H5 document against, how are we supposed to do document validation? And by document validation, I mean "how are we supposed to ensure our html5 documents are both syntactically accurate and structurally sound?" Please help!

Fact that there were two version of Silverlight in the past 18 months worries me, as well as the fact that over 97% of web browsers already have Flash pre-installed. I'm a .NET developer and I'm very happy with ...
HTML5 gives us some new input elements to play with, such as <input type=number>. This renders (in Chrome) as a textbox with two cycle buttons inside the textbox, for incrementing and decrementing the numeric value inside the box. For a personal hobby project, I'm using this control. However, I'm stuck with one issue: Is there a way to...
I'm using VideoJs to handle my HTML5 video needs, using a single M4V. I needed a playlist, and I'm able to change it's source easily using JS (in my case, jQuery). However, I'm not able to pass these changes along to the flash fallback (which is achieved via an object including flowplayer). Any ideas on how one might be able to dynamic...

I want to be able to draw a fitted rectangle around text labels (person's full name). The margin isn't terribly important, but I can't just draw fixed-sized rectangles because the labels vary in lengths. How do I do this? Here's the code that draws the text labels: var ctx = document.getElementById('map').getContext('2d'); for (i=0; i ...
