The class page always has up-to-date information on assignments, helpful tutorials, calendars and due dates for each student's maximized comfort in the class.
HTML Help is useful when it comes to tricks and simple tutorials. They introduce you to many interesting features, in addition to standard color codes and symbols.
This is my favorite site when it comes to HTML coding. There are so many ways to personalize your webpage, and the use of color is a big one! You can find background colors, font colors, and border colors here (they're all the same!) and use the codes for either word code or hexidecimal code.
