3.1 Browser problem with vertical margins

Microsoft's Internet Explorer 3.0 browser does not implement vertical margins completely. In particular:

• Bottom margins are not implemented at all.
• Paragraphs have a built-in margin that is not overridden by the CSS margins.
• Vertical margins do not collapse according to the CSS specification.

The problems listed above are fixed in the 4.0 release of Internet Explorer.

WebMaker 3.0 generates CSS instructions that adhere to the specification.
