CSS 单位

CSS 长度单位

在 Weex 中,所有样式支持px长度单位,部分样式支持wx

注意

  • Weex 不支持类似 emrempt,% 这样的 CSS 标准中的其他长度单位;
  • 单位 pxwx 不可省略,否则在 H5 环境无法正确渲染;

wx单位

使用 wx 单位可使尺寸不受屏幕宽度和 viewPortWidth 影响。以下是支持wx单位的样式。

  • 通用盒模型:
    • width {length}
    • height {length}
    • padding {length}
    • margin {length}
    • border-width {length}
  • Transform:
    • translate {length}
  • 文本样式:
    • font-size {number}
    • line-height {length}

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 opacitylinesflex 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
  1. .classA {
  2. /* 3-chars hex */
  3. color: #0f0;
  4. /* 6-chars hex */
  5. color: #00ff00;
  6. /* rgba */
  7. color: rgb(255, 0, 0);
  8. /* rgba */
  9. color: rgba(255, 0, 0, 0.5);
  10. /* transparent */
  11. color: transparent;
  12. /* Basic color keywords */
  13. color: orange;
  14. /* Extended color keywords */
  15. color: darkgray;
  16. }

注意

  • 只有上面列出的颜色格式被支持,其他颜色格式均被支持。
  • 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。
