I Cannot Believe It is not Flash: Guide to CSS Animating

CSS animations make it possible to animate transitions from one CSS style configuration to another. Animations consist of two components, a style describing the CSS animation and a set of keyframes that indicate the start and end states of the animations style, as well as possible intermediate waypoints along the way. There are three key advantages to CSS animations over traditional scriptdriven animation techniques: Theyre easy to use for simple animations; you can create them without even having to know JavaScript. The animations run well, even under moderate system load. Simple animations can often perform poorly in JavaScript (unless theyre well made). The rendering engine can use frameskipping and other techniques to keep the performance as smooth as possible. Letting the browser control the animation sequence lets the browser optimize performance and efficiency by, for example, reducing the update frequency of animations running in tabs that arent currently visible.

Raphaél—jJavaScript Library | L+ ®http:/ /raphaeljs.com/ C | (Qy raphaell Raphaél—JavaScript Library =”"t V7, Q> Raphaél—JavaScript Library \ A Nr T V V la f > ©

Raphael is a small JavaScript library that should simplify your work with vector Our recommendation is to GZIP it It graphics on the web If you want to create your own specific chart or image crop will help to reduce file size to 20 Kb

and rotate widget, for example, you can achieve it simply and easily with this You can download

library as well

Raphaél uses the SVG W3C Recommendation and VML as a base for

creating graphics This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later

Raphaél’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy

Raphaél currently supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet

Explorer 6.0+ Ask your questions there

Hope it will help

For more examples take a look at charting plugin:

How to use it? Best source of updates, so far

Download and include raphael js into your HTML page, then use it as simple as:

shows you how to download, install and

configure a web browser that can show WebGL content, and gives links to a set of pages that show what it can do

gives you an overview of how WebGL works, with enough code to simply draw a static triangle and a square on the screen

Duilds on lesson 1, and adds colour to the triangle and the square

builds on lesson 2, making the triangle and the square spin around

builds on lesson 3, bringing us into the third dimension fully by replacing the triangle with a

pyramid and the square with a cube

shows how you can use an image file to “skin” your 3D objects, giving you a quick and easy way to make them look more interesting
