In Internet Explorer 6, this pseudo-element fails if it??™s not immediately followed by
whitespace. This means that whitespace must appear between the pseudo-element
and the declaration block, as well as between the pseudo-element and the comma,
if the pseudo-element isn??™t the last selector in a group of selectors.
In Internet Explorer versions up to and including 7:
?– This pseudo-element doesn??™t work when it??™s used on a positioned element that
has a layout (p. 158).
?– This pseudo-element acts like a block element??”it spans the entire width of the
containing block instead of displaying inline (p. 166).
?– The list-item marker is included within this pseudo-element.
?– Bizarre specificity and inheritance problems affect this pseudo-element.18
