为了简化计算,在css中的body选择器中声明font-size=62.5%,这就使em值变为16px*62.5%=10px, 这样12px=1.2em, 10px=1em, 也就是说只需要将你的原来的px数值除以10,然后换上em作为单位就行了。 引自:http://www.w3.org/Style/Examples/007/units But in general you would use a different set of un...

<div style="font-size=12px"> <span style="fontsize=2em">这里的字是24px</span> </div> 如果使用em来指定填充,填充的宽度是相对于DIV元素的字体大小而定的.pt是印刷业上常使用的单位,磅的意思.一般也用于页面打印排版.以上三种PX是像素单位,EM是相对单位,PT是绝对单位.他们各自的好处是,...
2.3 使用相对单位(em和rem)设置字体大小 (Using Relative Units (em and rem) to Set Font Size) em和rem是相对单位,可以根据父元素或根元素的字体大小进行调整。例如: html { font-size: 16px; } body { font-size: 1rem; /* 16px */
