# CSS 长度单位
在 Weex 中，我们支持 px和wx 长度单位。对于不希望受屏幕宽度和 viewPortWidth 影响的尺寸，请使用 wx 单位。
注意
- Weex 不支持类似
em、rem、pt,%这样的 CSS 标准中的其他长度单位； - 单位
px或wx不可省略，否则在 H5 环境无法正确渲染；
# CSS 数值单位
在 Weex 中，除了长度单位外，还有数值单位，仅仅一个数值，后面没有 px 等单位。用于 opacity，lines，flex 等属性指定一个纯数值。
TIP
有时值必须是整数，例如：lines
# CSS 颜色单位
Weex 支持多种颜色单位：
- 精简写法的十六进制，如
#f00 - 十六进制，如
#ff0000 - RGB， 如
rgb(255, 0, 0) - RGBA，如
rgba(255, 0, 0, 0.5) - 色值关键字，如
red
.classA {
/* 3-chars hex */
color: #0f0;
/* 6-chars hex */
color: #00ff00;
/* rgba */
color: rgb(255, 0, 0);
/* rgba */
color: rgba(255, 0, 0, 0.5);
/* transparent */
color: transparent;
/* Basic color keywords */
color: orange;
/* Extended color keywords */
color: darkgray;
}
注意
- 只有上面列出的颜色格式被支持，其他颜色格式均不被支持。
6-chars hex16进制颜色值 是性能最好的颜色使用方式。除非有特殊原因，请使用6-chars hex格式。
