N a font type in which the width of letters and symbols varies depending on the letter or symbol 比例字体 [计算机]
We've done very little really, just avoided using absolute font sizes, and used proportional sizes for headings, and we've already made our pages much more adaptable and accessible.
以上我们所做的仅仅是避免使用绝对尺寸字体已经为可访问性带来很多帮助。
By proportional sizing we mean using percentages and em units for container sizes, field lengths, font sizes, and so on wherever possible.
成比例的大小改变(proportional sizing)指的是，对于容器大小、文本域的长度、字体大小等，尽可能使用百分数和em单位。
