Dear prawns, how can I center the DIV in the browser? If you set its margins, it will be different if you change the size of the monitor. Thank you! ! !
Reply to discussion (solution)
Set CSS:
div{
margin-left:auto;
margin-right:auto;
}
This requires dynamically setting the position of the Div
style="position:absolute;top={1}px;left={2}px;"
As above, your Div The style needs to be set to this, but top and left need to be calculated dynamically.
The problem is to dynamically obtain the size of the browser window. So the solution is as follows:
<html> <head> <title>DIV居中显示</title> <script type="text/javascript"> var setDivCenter = function(divId){ var oDiv = document.getElementById(divId); oDiv.style.position = "absolute"; oDiv.style.top = (document.body.offsetHeight - 150) / 2 + "px";//这个150是div的高度 oDiv.style.left = (document.body.offsetWidth - 200) / 2 + "px";//这个200是div的宽度 }; </script> </head> <body onload="setDivCenter('dvCenter')"> <div id="dvCenter" style="width:200px;height:150px;background-color:red;"> 我在浏览器的中间 </div></body> </html> I just wrote it and it has passed the test~~
Thank you very much! ! ! ! ! !
