I'm not a great fan of the various CSS reset rules because they can cause as many problems as they solve, in my opinion. I believe it's much better to learn how to recognize margin/padding issues and fix them on the locus where they are occurring than it is to affect every tag on the page in a way that could cause them to behave unexpectedly. Most often the problems such this are caused by an escaping margin (i.e., the FIRST tag within a container has a default margin that escapes from the containing envelope and creates an apparent space ABOVE the container. This can be most effectively solved in one of these ways -
1. Apply an overflow:hidden style to the container (only if the container does not have an explicit height).
2. Apply a 1px top border to the container (if you can match colors with the background)
3. Remove the top margin from the tag whose top margin is escaping with margin-top:0;
