320- <LI>CSS1 simply said that 'margin-right' was ignored if the both
321- 'margin-left' and 'width' were set. In CSS2 the choice between
322- relaxing 'margin-right' or 'margin-left' depends on the writing direction.
323-
324- <LI>In CSS1, several properties (e.g., 'padding') had values referring
325- to the width of the parent element. This was an error; the value
326- should always refer to the width of a block-level element and this
327- specification reflects this by introducing the term "containing block".
