HTML Quick Reference Guide

USE THIS DOCUMENT AS A QUICK REFERENCE for most common tags used in HTML. This reference is not exhaustive and does not attempt in all cases to distinguish among tags that are purely extensions of one browser or another. The tags below will work interchangeably in most browsers and versions. The rule of thumb is: try it and it is doesn't work or is ineffective, try the alternative tag. If a tag doesn't work and you want the greatest number of people and browsers to see an effect, use the simplest tag/approach for the lowest common denominator.
