I am creating my own little site that has the html and css that I use the most.  It is called "Cheat Sheet" because frankly, sometimes I just don't remember the syntax for all of the html elements or css properties.  I can just come to this site and refresh my memory - or just cut an past a snippet of code.  By design, it is meant to be a simple clean site without a lot of styling.

All of this information is already on the web of course.  But it is scattered about and it is time consuming to find just the right explanation, or it is buried among advertisements, fancy graphics, etc.

It is not a complete list of HTML or CSS by any means. You can find that at w3schools.com or a multitude of other sites.  I use those sites a great deal, but sometimes they fall under the TMI (too much information) category when I want a quick answer.
