This is very easy to do in Front Page with an include bot. Also big headers push the links down further on the web page and the students must scroll to the links. Avoid using red as a heading color, red connotes a warning. Avoid using multiple colors in a heading, it is too distracting. Avoid changing the font type and size with in a section of text.
Consistency is the key.
These may be very appropriate for personal home pages but not for educational pages. For easy reading and consistency pages should be the same background color. For easy reading by students, light backgrounds with dark text are the easiest to read. Make sure that your text color can be read over top of your background color. Remember that students will have different settings on their computers and will be using a variety of web browsers and the color settings will vary.
