通用单位：

  • px：像素（Pixels），绝对长度单位
  • pt：点（Points），绝对长度单位
  • pc：派卡（Picas），绝对长度单位，默认为浏览器缺省字体大小（16px）
  • em：相对长度单位，相对于当前对象内文本的字体尺寸
  • ex：相对长度单位，相对于字符“x”的高度，通常为字体高度的一半
  • cm：厘米（Centimeters），绝对长度单位
  • mm：毫米（Millimeters），绝对长度单位
  • in：英寸（Inches），绝对长度单位

换算关系：

  • 1pc = 12pt = 16px
  • 1in = 2.54cm = 25.4mm = 72pt = 6pc = 96px

    注：以 72 像素/英寸为基准
