[whatwg] Bad CSS on the multipage version

Perhaps it is a bug; but I would not expect it to work anyway.  It does not
seem a good idea to draw the background from the next element by
manipulating the margin.  If you want to have a common background, either
wrap both elements with a div (which would work for background images) or
declare the same background on the first element (which would work for
background colors).

Seems to be an IE CSS bug like in
http://software.hixie.ch/utilities/js/live-dom-viewer/?%3C!DOCTYPE%20html%3E
%0D%0A%3Cstyle%3E%0D%0A%20.a%20%7B%20border%3A2px%20blue%20solid%20%7D%0D%0A
%20.b%20%7B%20border%3A2px%20green%20solid%3B%20background%3Ayellow%3B%20mar
gin-top%3A-0.8em%20%7D%0D%0A%3C%2Fstyle%3E%0D%0A%3Cdiv%20class%3Da%3EThis%20
text%20should%20be%20visible%20on%20top%20of%20the%20yellow%0D%0A%20%3Cdiv%2
0class%3Db%3E...%3C%2Fdiv%3E%0D%0A%3C%2Fdiv%3E

That case fails in IE7; it works in IE8 (and in recent versions of
Firefox, Opera, Safari, Konqueror).

I don't know if there's a 'proper' way to fix this, but adding
   h4 { position: relative; }
into the page's CSS makes it work correctly in IE7, and doesn't affect
any other browser.
