IE6/7 and IE8/9/10 (IE7 mode) hides the parent and child elements with absolute or relative in turn, and then displays the parent element. The child element can still display bugs.

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 that the child element D2 can also be displayed (don't forget, D2 is displayed: none ). However, IE8/9/10/firefox5/safari4/chrome12 neutron element D2 is still hidden.
