Based on Wikipedia explanation, the team "cheatsheet" is a concise set of notes used for quick reference. "Cheat sheet" may also be rendered "cheatsheet". Here are some cheatsheets I found from Google search:

1. Cheat-sheets.org contains all popular cheatsheets in one web site.
2. HTML cheatsheet is good, but I prefer w3school tutorials, including HTML references.
3. CSS Cheat Sheet contains concise information about CSS styles.
