With all websites it is best to stick to a few common font - Arial, Times Roman, Verdana etc. because if the viewer doesn't have the font you wrote in, it doesnt display - it just shows their default font.

If your website has a coloured background make sure that you first put the same colour background in your word program before typing.
With Microsoft Word you can also save your typing as a html file, but to copy the piece you want from that can be hair-raising.
A very useful tool for matching colours is the free spectroscope at
