首先考虑css动画然后考虑js。

velocity：很全面的JavaScript动画库

vivus：可以动态描绘 SVG 的 JS 库, 支持多种动画

Web Animation：Javascript 实现的 Web Animation API

scrollReveal.js：使元素以非常酷帅的方式进入画布 (Viewpoint)

snabbt.js：一个利用 Javascript 和 CSS transform 的 animation 库

transit：jquery实现的css动画

matter-js：2D 物理效果引擎，碰撞、弹跳等

parallax：一个用于响应智能手机 orientation 的库

focusable：是页面上一个元素高亮的库，关灯效果

sensor.js：在智能移动设备浏览器上，通过HTML5的api使用移动设备的功能。定位、运动、倾斜等

animatable：仅仅依靠 border-width 和 background-position 实现的各种动态效果

Bounce.js：漂亮的css3动画库

GreenSock：基于svg，很强大的动画效果，High-performance HTML5 animations that work in all major browsers.

dynamics.js：弹性物理效果

使用DIV,CSS样式来做！

一般现在使用3P来实现，如APS.NET！

你可以拷贝一个脚本修改里面的参数，就可以达到效果了！

使用html代码，只能使用一个！

就是跑马灯标签来实现简单的效果！

<marquee></marquee>这个标签！

如：

<marquee direction=left scrollamount=6 onmouseover=
