技术要点:
一个覆盖整个屏幕的浅灰色背景的div,一个包含内容的的div,
代码如下:
$(document).ready(function(){ var m1_top = ( $(window).height() - $("#financeTipInfor").height() )/2; var m1_left = ( $(window).width() - $("#financeTipInfor").width() )/2; $("#financeTipInfor").css({"margin": m1_top + "px" +" "+ m1_left + "px"}); window.onresize=function(){ var m1_top = ( $(window).height() - $("#financeTipInfor").height() )/2; var m1_left = ( $(window).width() - $("#financeTipInfor").width() )/2; // $("#financeTipInfor").css({"margin": m1_top + "px auto","left": m1_left + "px"}); $("#financeTipInfor").css({"margin": m1_top + "px" +" "+ m1_left + "px"}); } $(".close").click(function () { $("#financeTip").css({"display": "none"}); });});
#financeTip{width:100%;overflow:hidden;}.financeTankuang{width:90%;}@media (min-width: 768px){.financeTankuang{width:600px;}}.financeTipBg{position:absolute;width:100%;height:100%;background:#000;z-index:8001;left:0;top:0;opacity:0.2}#financeTipInfor{position:absolute;left:0;top:0;z-index:8011;}
