这是一款来自Doodle的创意作品,它是一个基于HTML5 Canvas的电吉他,当我们将鼠标滑过吉他的弦时,电吉他将会发出美妙的声音,更加酷的是,你可以利用键盘来弹奏一首悦耳的乐章,非常强大的HTML5。

这是一款十分炫酷的HTML5 3D书本翻页动画,效果相对比较简单,拖拽鼠标模拟用手翻页,更漂亮的是翻页过程中,呈现出逼真的3D立体效果。书本中的文字和图片也会3D展示,非常酷。

这是一款基于HTML5和CSS3的3D动画特效,与之前的3D特效不同的是,这款是完全用HTML5特性实现的,而并非用多张图片叠加起来。这款3D动画还有一个特点是可以无限的旋转,从而可以从多个视角来观察HTML5 Logo。
