Question

前端移动端页面怎么用rem布局

Answer 1

!new function(){var a=this;a.width=750,a.fontSize=100,a.widthProportion=function(){var b=(document.body&&document.body.clientWidth||document.getElementsByTagName("html")[0].offsetWidth)/a.width;return b>1?1:b},a.changePage=function(){document.getElementsByTagName("html")[0].setAttribute("style","font-size:"+a.widthProportion()*a.fontSize+"px !important")},a.changePage(),window.addEventListener("resize",function(){a.changePage()},!1)};
引入这段js代码，设计图的750px = 7.5rem ，同理10px = 0.1rem
记得在css设置默认字体大小 body{font-size: 0.3rem;}
举例：.div1{width: 7.5rem;height: 1rem;}
