Here are some reasons they mentioned: While contemporary Web browsers do an increasingly good job of parsing even the worst HTML “tag soup”, some errors are not always caught gracefully.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.
Some qualifications require specific evidence and you should check your units to see what is needed. It simply means collecting enough evidence to demonstrate evidence you put forward.In the past, many authors who relied on the quirks of Netscape 1.1 suddenly found their pages appeared totally blank in Netscape 2.0.Whilst Internet Explorer initially set out to be bug-compatible with Netscape, it too has moved towards standards compliance in later releases.Beginners and students, on the other hands, will find automated checking tools invaluable in spotting mistakes.Some teachers also stress that automated validation tests are a good introduction to broader, more complex quality concepts such as accessibility.Validation can then be used as a quick check to determine whether the code is the clean work of a seasoned HTML author, or quickly hacked-together tag soup.
Validation, as any process of debugging code, is sometimes difficult, and the vast improvements in automatic error correction has made modern browser cope very well with errors in HTML or CSS.
It is indeed one of the principal strengths of the web, that (for example) a visually impaired user can select very large print or text-to-speech without a publisher having to go to the trouble and expense of preparing a separate edition.
Do remember: household-name companies expect people to visit afford that luxury?
To do this you need to organise your evidence into what is known as a portfolio.
This page is intended to provide useful guidance and support to you when you come to gather your evidence.
Even if you can, do you want to risk being on the wrong side of a lawsuit if your site proves inaccessible to - for instance - a disabled person who cannot use a 'conventional' browser? Whilst validation doesn't guarantee accessibility (there is no substitute for common sense), it should be an important component of exercising "due diligence".
