所以你已经听说所有关于HTML5将取代Adobe Flash的谣言。虽然大多数网络社区都认为这是可能的，但你一定在徘徊是什么让HTML5如此强大，甚至连苹果大公司都想用它来取代Flash。
这就是为什么这篇文章存在的原因，我们不打算谈论HTML5可以做什么，而是展示HTML5可以用其他语言（如JavaScript）实现的神奇事情的现场演示，所以准备好受到启发。
注意：由于某些Web浏览器（如Internet Explorer）不完全支持HTML5，因此强烈建议您使用Firefox浏览器查看下面的所有HTML5演示。
动画
HTML5的canvas元素是HTML5取代某些Flash动画的决定性因素。它允许您使用Javascript构建2D形状和位图图像的动态，可编写脚本的渲染，换句话说，这是可控的动画。
