The resize event does not work for the framework when the browser window size changes, as follows:

$(window).resize(function(){
var surH = $(window).height();
$(".pic_conent").height(surH);
}

When the browser changes, pull the size, there is no response;

Method 1: add   to the label; OnLoad = "" onResize =” & “have spent Method   Method 2: window.onresize=function(){///… Write the corresponding code in the method, and the two methods can basically solve your problem

window.onresize=function(){
var surH = $(window).height();
$(".pic_conent").height(surH);
 }
