Validation

I don't understand it. Could someone please explain why it is needed on a
web site.

Btw, this is the wrong group for such questions.

Validation does not make sure that a web site works properly, far from
it in fact.

It checks that your HTML conforms to the subset of the specification which
is expressed in a machine readable form called a DTD.

Validity is form of quality assurance that is very easy to achieve.

Code that does not conform to the specification requires that user agents
perform guesswork as to what the author intended to say, or ignore sections
of code entirely.

Problems with the rendering of code could be caused by mistakes in the page,
or mistakes in the user agent. Validity dramatically reduces the chances of
the former.

There are hundreds of different user agents out there, testing on all of
them is impossible, and they can't be expected to be able to make the same
guesses when they try to correct an author's errors (if they try at all).

Valid code is generally much easier to debug then invalid code.

Valid code is generally much easier to maintain then invalid code.

If you ask other people to look at your code, then making it easier for them
by being valid is respectful and libel to make them more inclined to help.

It is not needed _on_ a site at all.
You pass pages from your site _through_
it so that they may be either blessed or cursed.

Although not actually a member of the w3c, I have assumed the arduous
duty of selling indulgences to owners of cursed pages.
Such indulgences may be purchased from yours truly at a rate
I deem to be fair.

Those with cursed pages who refuse to
obtain indulgences will remain in website-purgatory, forced to watch Mel
Gibson snuff flicks until they pay up or become terminally
paranoid or bored.

Please write for a beautifully marked-up and styled table of rates,
available at a minimal price. As a prerequisite,
please write for a table of the minimal prices, also available at a
minimal price.

Please do not attempt to rectify cursed pages by correcting their
markup or styles -- once you've fallen from grace, your petard is hoist.
So, pay up or face the consequences. Anyone correcting cursed pages
will be sent straight to hell, where they will be forced to listen
to the slurred and illogical speeches of G. W. Busch, live, for eternity.

Validation does not make sure that a web site works properly, far from
it in fact.

Not exactly, but it will make it make it render properly across various
browser platforms and make it more search engine spider friendly.

Nonsense on both counts.

Second bit's right.

Not at all. The only thing validation does is remove syntax errors as a
cause of possible rendering problems. Browsers still have bugs, and a
validated page is no guarantee that you won't trigger one.

Validation does not check for logic errors, either, so illogical use of
markup can just as easily cause rendering glitches as syntactically
incorrect markup.

I don't believe engines worry their softwarey little heads about
rendering problems, just about interpretation of the contents of the
site. If it validates, they can assume that they have a fair handle on
the contents, if not, they can't.
