HTML5
Let me start by saying that HTML5 and CSS3 are two different things. Secondly HTML5 is still just HTML and CSS3 is still just CSS. I’ve been noticing that people are confusing these two specifications with each other and making it more complicated then it is.
HTML5 Forms Styled With CSS3
Web Forms 2.0 est une extension qui vient enrichir les caractéristiques des formulaires HTML en prévoyant de nouveaux champs de saisie fortement typés, de nouveaux attributs pour la définition des contraintes, un modèle de répétition des sections de formulaire, de nouvelles interfaces DOM, de nouveaux événements DOM pour la validation et la soumission des formulaires et plus encore. Malheureusement, même les navigateurs modernes sont loin d’implémenter toutes les fonctionnalités offertes par Web Forms 2.0. En revanche, il existe une librairie Javascript nommée webforms2 qui permet de l’implémenter dans la plupart des navigateurs.

Badass JavaScript - Face Detection in JavaScript via HTML5 Canvas
You have probably seen face detection at work in programs like iPhoto and Picasa, but what if you could do that performantly in JavaScript? Chinese developer Liu Liu has done the honors, and implemented the algorithm using the canvas element. The algorithm is implemented on top of a JS port of a C-based computer vision library by the same author. It works off a grayscale version of the image, and seems to be quite reliable in detecting faces in photographs. The demo then draws a red box around each face in the picture, but the library could be used to do much more interesting things with this data.
