In most cases, hide (set display: None) an element. You do not need to hide all its child elements in sequence. To do this, you may encounter unexpected bugs. As follows:
1, two divs, D1 contains D2
Both D1 and D2 have absolute or relative.
3. Hide d1
4. Hide the child element D2.
5. Display d1
At this time, IE6/7 and IE8/9/10 (IE7 mode) will find tha
As follows:

At this time, IE6/7 and IE8/9/10 (IE7 mode) will find that the child element d2 can also be displayed (don't forget, d2 is displayed: none ). However, IE8/9/10/Firefox5/Safari4/Chrome

Then Ie6/7 and IE8/9/10 (IE7 mode) will find that the child element D2 can also be displayed (don't forget, D2 was Display:none OH). But the Ie8/9/10/firefox5/safari4/chrome12 neutron element D2
