介绍
Emmet (前身为 Zen Coding) 是一个能大幅度提高前端开发效率的一个工具。
基本上，大多数的文本编辑器都会允许你存储和重用一些代码块，我们称之为“片段”。虽然片段能很好地推动你得生产力，但大多数的实现都有这样一个缺点：你必须先定义你得代码片段，并且不能再运行时进行拓展。
Emmet把片段这个概念提高到了一个新的层次：你可以设置CSS形式的能够动态被解析的表达式，然后根据你所输入的缩写来得到相应的内容。Emmet是很成熟的并且非常适用于编写HTML/XML 和 CSS 代码的前端开发人员，但也可以用于编程语言。
示例在编辑器中输入缩写代码ul>li*5，然后按下拓展键（默认为tab），即可得到代码片段：
<ul> <li></li> <li></li> <li></li> <li></li> <li></li></ul>下载和安装
