In the mobile UI, I want to layout three DIVs. TOP is the upper part, FOOTER is the lower part, and op_float_bar is at the bottom inside TOP. How to set the height of this DIV?
#top { width:100%; height:? ? ? ;}

//The upper layer accounts for 70% of the height of the entire phone

// The BAR in the upper layer is at the bottom of the upper layer, accounting for 20% of the upper layer

You may wish to learn jquery-mobile???

If you insist on setting it manually, you can use jq

<!DOCTYPE html><html><head><script src="http://www.w3school.com.cn/jquery/jquery-1.11.1.min.js"></script><script type="text/javascript">$(function() {	//获取页面的可视区域高度和宽度	var wHeight=document.documentElement.clientHeight;	var footerH= $("#footer").height();	var newH=wHeight-footerH+"px";	//alert(footerH.height());	$("#top_float_bar").css("height",newH);});  </script></head><body><div id="top" style="background:yellow;">123</div><div id="footer" style="height:300px;width:500px;background:red;"></div></body></html>

The code is for reference only.

Sorry, please modify it,, you don’t need to add px when assigning value

That’s it, I’ve tested it for you

The other two are fine, but 20% The bottom should be aligned with the bottom of the upper part of 70%, but it still doesn't work. Now 20% is on top of 70%.

html,body{
height:100%;margin:0;
overflow:hiden;
}
#top{
height:70%
}
#top #top_float_bar{
height:20%
}
#footer{
height:30%
}
