Problem: when the green DIV is displayed, it's okay to move the mouse into the DIV, and move it to a small local area (above the four letters of aaaa) on the top of the aaaa. The DIV is closed. I don't know why.
<Div style = "margin: 0px auto 0px auto; position: absolute; left: 250px; top: 250px; padding: 20px; z-index: 1;">
<Asp: LinkButton ID = "LinkButton1" onmouseover = "over (this, document. all. se) "onmouseout =" timer = setTimeout ('out (document. all. se) ', 500) "OnClientClick =" alert ('left' + this. offsetLeft + '; top' + this. offsetTop + '; height' + this. offsetHeight + '; Kuan' + this. offsetWidth); return false; "runat =" server "> M me </asp: LinkButton>
</Div>
<Div id = "se" onmouseover = "clearTimeout (timer); this. style. display = 'block' "onmouseout =" out (this) "style =" background-color: # 32ba5c; display: none; width: 200px; position: absolute; padding: 20px; ">
<Div> aaaa </div>
<Div> bbbb <input type = "button" onclick = "this. parentElement. parentElement. style. display = 'none'" value = "close"/> </div>
<Div> aaaa </div>
<Div> bbbb </div>

<Div> bbbb </div>
