The style declarations which apply to the text below are:
P.six {margin: 200;}
P.sixa {border-width: 200; border-style: solid;}

P.sixe {border-top-width: 200 px; border-style: solid;}
P.sixf {border-width: medium; border-style: solid;}
This paragraph should not have any extra spacing around it, because the margin does not have any units, and is therefore invalid.
This paragraph should have a medium-width border around it (the same as the next five paragraphs), because the border-width does not have any units, and is therefore invalid.
This paragraph should have a medium-width border around it (the same as the previous one and next four paragraphs), because the border-width units are invalid, and therefore the border-width should be ignored.
