Page Validation
Why do page validation?
Validation as a debugging tool
Very often, different software on different
platforms will not handle errors in a similar
fashion, making it extremely difficult to
apply style or layout consistently.
Page Validation
Why do page validation?
Validation as a debugging tool
Using standard, interoperable markup and
stylesheets, offers a much greater chance
of having one's page handled consistently
across platforms. Most developers creating
rich Web applications will make sure that
their markup and CSS is validated before
creating a rich interactive layer.
Page Validation
Why do page validation?
Validation eases maintenance
Creating Web pages or applications
according to a widely accepted coding style
makes them easier to maintain, even if the
maintenance and evolution is performed
by someone else.
Page Validation
Why do page validation?
Validation as a future-proof quality check
Checking that a page “displays fine” in
several contemporary browsers may be a
reasonable insurance that the page will
“work” today, but it does not guarantee
that it will work tomorrow.

Validation helps teach good practices
Beginners and students will find
automated checking tools invaluable in

Device compatibility- Websites that
separate the structure from the style are
more easily repurposed for mobile devices
and other browsers. CSS also allows for
alternative style sheets that optimize the
appearance based on the device being
used to view the page.
Page Validation
Why do page validation?
Validation is a sign of professionalism
As of today, there is little or no certification
for Web professionals, leaving most Web-
smiths to learn by themselves, with varied
success.
Validation can then be used as a quick
check to determine whether the code is
the clean work of a seasoned HTML author.
