Interesting - on the original site (the 2nd link) - only the text below the copyright bar, and a few spaces between the boxes changed.

look up some HTML coding reference sites (someone will provide links I'm sure)
The necessary commands to look for are

1) Font Color = (setting the font colour to the background colour makes it seem 'invisible') there are a few common color names, but you can specify the absolute color as a string of numbers

2) Font Size =

you can also force the font name to be specific if you really want - but if the viewer does not have that font, a default font will be substituted. Also IE can be set to ignore the author specified font and display fonts specified by the viewer.
