What is W3C validation and why is it important?

What is W3C validation?

We in the “web world” tend to use scary words and acronyms when talking about what we do and it is very possible you have heard of “W3C” or “W3C standards” or maybe even “W3C validation” and wondered what in the world a this strange jumble of letters and numbers has to do with your website! I’ll translate this from “Tech” into English for you.

 

First, let’s define who and what the W3C is.

W3C stands for the World Wide Web Consortium who are the recognized standards organization for the world wide web. This organization was founded by Tim Berners-Lee and is run by a full-time staff to continue to develop and maintain web standards. These standards are then used to help guide web developers and browsers to develop code that lives up to certain standards. In a nutshell, they write the rule-book that helps to define if our code is well-written or poorly written. This is how we know if our markup (code) is awesome or not-so-awesome.

 

Ok, so what is W3C Validation?

We have established that there is a “rule-book” to define how we write our HTML, CSS, Javascript, etc and make sure we do a good job, right? Well the programming languages we use all have their own grammar, vocabulary and syntax just like a spoken language and that means that it can be written wrong if it does not follow the rules. When we say we write “W3C valid code” or that “our websites pass W3C validation”, we are saying that the code we write and websites we build will pass W3C validation tests without errors because our syntax and “grammar” is correct. It means we wrote awesome code that was done right.

It’s all a very complicated way of saying that W3C Validation is a test that makes sure we follow the rules!

A tool is provided by the W3C to test websites and can be found this link: http://validator.w3.org. We use this tool on all of our websites.

 

Why is it important that your site is W3C Valid?

A great question! I’m glad you asked. It’s important that your site is W3C valid to ensure the site works properly on your browser as well as the other major browsers such as Internet Explorer, FireFox, Chrome, etc. A website that contains many errors can suffer from many ill-effects.

The following are just some of those ill-effects:

  • Not displaying properly or consistently
  • Not compatible with all major browsers
  • Not displaying properly on devices of varying sizes like mobile devices
  • Ranks badly in search engines (because they can’t read the code)
  • Loads elements slowly

Additionally, websites that are coded to standards last longer and are “future-proofed” for the most part against browser updates and the like. If your code is bad, the chances of your website breaking as browsers update is greater than if the code validated. We believe in value for our clients and what good is a website that breaks a few months later!?

Wrapping it up.

Keeping in mind that a website can be coded with valid W3C markup, but still not be done well or properly in other ways, however this is a good test to see how well the site was coded.

Every website should meet W3C validation standards if at all possible. It is not only the “right” way to do it, but it has many lasting benefits, such extending the sites life expectancy, ensuring compatibility across browsers, increasing load-speed in many cases and much more. Hopefully this helps you understand why we think it is so important and why we test all of our websites for W3C validation before deeming a project complete.
