css display：none和visibility:hidden和visible="false"区别

 

如果在div的style中把visibility设为 hidden则div隐藏，但是它会占据空白空间，而如果设置成display：none则不占据空白空间；
而visible="false"则div不返回在html中；下面是给出的代码：运行一下就知道区别了。

<% @ Page Language ="C#" %>

 

<! DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

< html xmlns ="http://www.w3.org/1999/xhtml">

< head runat ="server">

 

< title > Untitled Page </ title >

</ head >

< body >

 

< form id ="form1" runat ="server">

 

< div >

 

aaa

</ div >

 

< div style =" display : none ; "> <% --不占据空白空间-- %>

aaa

</ div >

</ div >

 

< div style =" visibility : hidden"> <% --占据空白空间-- %>

aaa

</ div >

 

< div id ="Div1" runat ="server" visible ="false"> bbbbbbb </ div >

 

< div >

 

aaa

</ div >

 

< div id ="Div2" runat ="server" visible ="false"> bbbbbbb </ div > <% --在html中不存在-- %>

</ form >

</ body >

</ html >
