"Style
sheets" are on of the many tools that makes the generation of a
whole system of linked HTML
documents, called a HTML project or simply
project a lot easier. You will not need style
sheets if you only want to make a few pages. The classes we
just discussed, are part of a style sheet. |
|
 |
Style sheets were introduced just a few years ago, they make
the life of HTML-writers a lot easier. Browsers, of course, must "understand" style
sheets. |
|
|
The name "stylesheet" is just a defined expression that
tells browser what to do (If the "REL" attributes of the
specific links is filled in properly). Loosely
speaking, we may call the contents of our special "styles" file the style sheet of a collection of HTML documents
that are supposed to look the same - to have the same style. |
|
Take one of the Hyperscripts as example. There is
a file for each chapter that contains a number of sub files always containing,
- The text of the chapters and paragraphs (here called "backbone"
- The exercises
- The linked documents explaining "basic" things
- The linked documents explaining "advanced" things
- The illustrations - HTML
documents and the pictures themselves.
|
|
|
Now you want the style of each chapter to be always identical
(but easily changeable), but different from the other chapters - maybe you want
to have specific background colors or whatever. |
|
|
So you add a style file
that contains the styles of this chapter to the other files contained in the
chapter and make links wherever needed to this chapter style file. |
|
What should be contained in the style file?
Essentially two items: |
|
|
Your class sheets (you may have several with different names;
maybe a special one for the backbone and another one for the rest. |
|
|
Your little graphical tools or icons - in our case the
triangles and the spheres and anything else that you might use |
|
So there is nothing to using styles and style
sheets - but think carefully about the system you are about to install! How
many style folders at which level of you file hierarchy are you going to
need? |
