How Important is W3C Validation for Your Website?

Validation is one of the important factors that determine the quality of web design. It refers to comparing formatted HTML and XHTML files with the defined W3C standards.

What is W3C?

W3C is referred to as World Wide Web Consortium which is being defined as standard coding guidelines. All markups and coding are subject to abide by W3C to run forward with future business aspects.

It is similar to checking your sentence in accordance with the general grammar rules of language in which it has been written. Just like there are rules in grammar language, similarly, in computer programming, there is a set of rules which must be followed during every website project.

W3C validation ensures the following:

  • Your website would be easily surfed by several types of Internet-accessible devices such as smartphones and ipads.

  • W3C validation shrinks the code size on your web pages and adds value to your web content.

  • Your website and its components would load faster on a wide range of browsers.

  • W3C compliance is fully compatible with an array of scripting languages, dynamic pages, multimedia presentations and more.

According to a survey, most of web designers and professionals have mentioned that validation errors are the first thing they will inspect in a website’s design. This makes it more important for your website to ensure that your CSS and markup languages are W3C validated in order to create interactive layouts for your website.

One of the most important advantages of W3C validation is that it effectively eliminates the unnoticeable coding errors that cannot be detected. This encourages the programmer to incorporate a variety of styles and layouts in your website’s design.
