A:hover span Hide/show issues

: Hover is one of the most commonly used pseudo-classes in CSS design, many brilliant effects can not be achieved without pseudo-class: hover, such as our common CSS menu, album effect and so on.

Perhaps it took so long to pseudo-class: hover, and some friends do not fully understand the rules of hover:

Reference:
In CSS1, this pseudo-class is available only for the A object. This pseudo-class does not work for a-object that has no href attribute (attribute).
In CSS2, this pseudo-class can be applied to any object.

But currently IE5.5, IE6 only support CSS1 in: hover, but the new IE7 is supported CSS2: hover.

When we use pseudo-class: hover do some special effects, according to CSS2 well done, but in order to occupy the mainstream browser IE6, we have to do a lot of work, such as adding a elements to simulate the final effect.

IE BUG: When the <a> elements adopt position, it is necessary to add a background to show the control range of <a>, otherwise the mouse slide over without any effect.
