样式也牛逼：
margin: 10ex 20em;, m10ex-5 → margin: 10ex -5px;.
Value aliases
Emmet has a few aliases for commonly used values:
You can use aliases instead of full units:
w100p → width: 100%m10p30e5x → margin: 10% 30em 5ex
Color values
Emmet supports hex color values, like this: c#3 → color: #333;. The # sign is a value separator so you don’t need to use hyphen to separate it. For example, bd5#0s expands to border: 5px #000 solid: the #sign separates color from 5 and since s (alias to solid) is not a hexadecimal character, it can be used without- value separator.
You can write one, two, three or six characters as color value:
#1 → #111111#e0 → #e0e0e0#fc0 → #ffcc00
