There’s a lot of buzz flying around at the moment about W3C Compliance. What is interesting is the number of people who discuss it, but don’t really understand what it truly means. To have a thorough understanding of W3C Compliance, you need to understand its origins.
The World Wide Web Consortium (W3C) was formed in 1994 by Tim Berners-Lee (The man widely credited with inventing the World Wide Web) as a group of web enthusiast, that would later be responsible for develop the standards that the World Wide Web would use.
The W3C worked hard to suppress the large number of incompatible and poorly established versions of HTML (HyperText Markup Language, the primary format of Web Pages). They endeavoured to adapt evolving technologies and methods, whilst still ensuring a high degree of compatibility and industry acceptance. To this day, the W3C remains the primary authority on Web standards.
When software manufacturers produce Web Browsers (Such as Microsoft’s Internet Explorer), they build the browser engine (The central component of the browser, which is used to draw and format web pages) with the ultimate goal of achieving the highest degree of compatibility with W3C standards that is possible. By ensuring compatibility with the standards, they in turn increase the Web Browser’s ability to render (draw) W3C-compliant pages in a manner faithful to the designer’s vision.
In the early days of the World Wide Web, W3C Compliance was simple, as there was only one standardized Web page format (HTML), and only a few dozen HTML “tags” (Commands). In 2009, there are 28 W3C Standards, and over 1000 validated tags. This ever-increasing complexity makes it more difficult than ever for Web Designers to ensure 100% W3C compliance when creating websites.
It is worth noting that while 100% W3C compliance is achievable, and ideal, it is not a prerequisite for a high-quality website. Many popular websites are not 100% W3C compliant (Such as the Google search engine), yet are highly compatible with every major browser on the market.
Within the Web Design community, W3C Compliance is not just a viewed as a method of Quality Control, it is seen as a display of competence and dominance is the industry. Many major Website Design companies now produce 100% W3C Compliant website, with some even authoring websites exclusively in the XHTML Strict format (a variant of HTML that requires all code to be 100% valid and functional).
In Short, 100% W3C Compliance ensures the very highest level of compatibility for websites across a wide variety of platforms and devices. Whilst achieving 100% compatibility can be a tall order, putting in the extra effort to get that figure as high as possible will ensure visitors have the best experience.
