Video for Everybody! Video for Everybody is simply a chunk of HTML code that embeds a video into a website using the HTML5 <video> element, falling back to Flash automatically without the use of JavaScript or browser-sniffing. It therefore works in RSS readers (no JavaScript), on the iPhone / iPad (don’t support Flash) and on many browsers and platforms. Thanks to the rapid adoption of HTML5 video happening right now, Video for Everybody isn’t the only solution around. It is not a neatly packaged, fully-featured solution for those unfamiliar with HTML. VfE is for developers who either want something really simple they can quickly use on their blog or websites, or as a good starting point to develop their own custom solution. It does not use JavaScript. Browser Ball Browser Ball attempts, with only moderate success, to allow the configuration of a seemingly endless array of continuous spaces using multiple overlapping browser windows. Within this multivariate space, users are invited to toss a beach ball both hither and yon. If this sounds like a ridiculous use of everyone's time, that's only because it is.

Frameworks, Boilerplates And Tools For Responsive Web Design There have been lots of complaints regarding responsive web designs especially from those web designers who preferred to be really creative and innovative with the website designs that they are used to create and their layouts. In a way, responsive web design has brought web design back to flatness, grids and boxes, but if you think about it well, that’s what web design is about, manipulation of grids and boxes. It’s not like creativity is gone with RWD, it’s still there, but different. Responsive web design and its techniques are in fact the best way to address the reality of the multi-device web, making use of less so that it can deliver more, the ‘more’ being represented by the actual content, the thing that matters. Even if others won’t admit it, responsive web design is taking us to a better web, one where we are realizing what’s important for the user in a contextual environment. This outrage against fresh standards isn’t at all a new thing.

Screenshots of HTML5 progress bars with different styles applied. CSS Sprites: What They Are, Why They're Cool, and How To Use Them This post was originally co-authored in late 2007 by me and Volkan Görgülü, I'm updating it now to improve it a bit and make it more current. You've heard of them, but... Do you really understand them? The name might be a little misleading, because sprites aren't little images like you might be picturing, a sprite is actually one big image. Have you ever seen the CSS technique where the "on" and "off" states of a button are contained within the same image and are activated by shifting the background-position?

Code inComplete - Javascript Gauntlet - Entities Last time we looked at how to parse image files in order to build up our map levels. Now we are going to take a closer look at the entities that make up the level itself. There are a number of different types of entities in a Gauntlet game, but we are going to concentrate on the primary ones: Treasure Monsters & Generators Players If you understand how these entities work, then the other types (Doors, Weapons, Exits, and Visual FX) should be easy to understand.
