In Internet Explorer versions up to and including 6:
?– :hover is applied only to HTML a elements that have an href attribute.
?– :hover is counted as two classes/pseudo-classes in the specificity calculation.
?– :hover is ignored if it??™s not in the last simple selector.
Neither Internet Explorer 5.5 nor 6 supports the chaining of pseudo-classes; only
the last pseudo-class is honored in these browsers.
In Internet Explorer 7:
?– The element sometimes remains in the hover state if the cursor is moved from
the element while the mouse button is pressed; the hover state sometimes doesn??™t
apply when it should.
?– :hover doesn??™t match elements with negative z-index property values.
