Colors
You control the colors of the background, text, links, etc using
Hexadecimal notation in a form like this:
< BODY BGCOLOR=#640064 TEXT=#FFFF00 LINK=#0000FF
ALINK=#FF0000 VLINK=#00E000 >
where each hex number is an RGB triple, i.e., #640064 means 64(hex) Red,
00 (hex) Green, and 64 (hex) Blue. The good news is that you don't
have to really know how to convert colors to hex. There are background
color WWW pages you can use to make this very easy to do: click on
either
ColorMaker or
HTML Color Selector
They let you experiment with different color schemes and automatically
create the HTML color codes for you. Note that ColorMaker also lets you
experiment with different backgrounds as well.
Backgrounds
Textured backgrounds must be used with care because they
can sometimes interfere with images, but they are frequently used.
You specify them as follows:
< BODY BACKGROUND="back.gif" >
where "back.gif" is some (small) GIF file. The background command
automatically "tiles" the image, that is it fills the screen with
replicas of the GIF file forming a background. See
Backgrounds
for many
examples.
Transparencies
Transparent backgrounds are very effective, especially if the graphic is
moving over the page. Many systems let you create such backgrounds.
Elsewhere in this class we demonstrate it using
PaintShop Pro and PhotoShop.
