rem的用法_html/css_WEB-ITnose
rem 是css3中的属性,ie8下不兼容。
rem是相对于根元素 这就意味着我们只需要在 根目录加入以下css代码。 默认单位为16px,我们需要在用rem的时候除以16 就是rem的值。 比如字体是20px,
20÷16 = 1.25rem即可。
@media only screen and (max-width: 320px) { html { font-size: 16px; }}@media only screen and (min-width: 321px) and (max-width: 360px) { html { font-size: 18px; }}@media only screen and (min-width: 361px) and (max-width: 375px) { html { font-size: 18.75px; }}@media only screen and (min-width: 376px) and (max-width: 384px) { html { font-size: 19px; }}@media only screen and (min-width: 385px) and (max-width: 413px) { html { font-size: 19px; }}@media only screen and (min-width: 414px) and (max-width: 480px) { html { font-size: 20.7px; }}@media only screen and (min-width: 481px) and (max-width: 540px) { html { font-size: 27px; }}
