Does W3C Validation Matter?

My site looks right and works fine – isn’t that enough?

Making sure your website is W3C valid is an important issue that is rarely addressed by many agencies today; the world wide web consortium made these open standards available to the international community to ensure long-term growth of the web. It is important that we follow these standards for a number of reasons. I will only go over the top three important points in this post, with a link to the entire list directly from W3C themselves.

REASON #1

Validation as a debugging tool

“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.

Using standard, interoperable markup and stylesheets, on the other hand, offers a much greater chance of having one’s page handled consistently across platforms and user-agents. Indeed, most developers creating rich Web applications know that reliable scripting needs the document to be parsed by User-Agents without any unexpected error, and will make sure that their markup and CSS is validated before creating a rich interactive layer.

When surveyed, a large majority of Web professionals will state that validation errors is the first thing they will check whenever they run into a Web styling or scripting bug.”

REASON #2

Validation eases maintenance

“It is reasonable to consider that standards such as HTML and CSS are a form of “coding style” which is globally agreed upon. 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.”

REASON #3

Validation is a sign of professionalism

“As of today, there is little or no certification for Web professionals, and only few universities teach Web technologies, leaving most Web-smiths to learn by themselves, with varied success. Seasoned, able professionals will take pride in creating Web content using semantic and well-formed markup, separation of style and content, etc. 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.”
