vue页面初始化大小rem，自适应效果设置

window. onload = function(){

getRem( 750, 100)

};

window. onresize = function(){

getRem( 750, 100)

};

function getRem( pwidth, prem){

var html = document. getElementsByTagName( "html")[ 0];

var oWidth = document. body. clientWidth || document. documentElement. clientWidth;

html. style. fontSize = oWidth/ pwidth* prem + "px";

}
