Add tags to posts?

[Caleb]

I was wondering if there was html code that allowed you to add a tag
to a post, that could then be called at any time. Example: Let's say
I have a website on different types of food. I create a page on
bananas and I want to add a tag that says the banana is yellow,
another that identifies it as a fruit, and another that tags it as
healthy. Now on my website I have three links that organize food
based on color, type, and how healthy it is. So I have two
questions. How do I add that to a certain post, and how do I call
that so if someone wants yellow food it shows up, in addition to
lemons etc. I know this is really confusing but I'm a complete noob
with html so as much description as possible would be awesome. If
this is completely confusing please ask and I will try to clarify.
Thanks so much for your help.

You would need some software that can read all the HTML documents on your
site, and generate (either statically or on-demand) pages which meet
specified criteria.

Ok, thanks. So there is now way to call all websites witht he tag
color yellow to one section?

As mentioned, you have software which reads the webpages, remembers which
ones have the meta data "the colour is yellow", and then produces webpages
based on that data.

This is a vast topic, far mor than can be discussed in a single usenet
