What Is W3C Validation?
Most pages on the World Wide Web are written in various computer languages (such as HTML) that allow Web Developers to create pages full of text, multimedia content, and specify what the general "look" of that page should have. As you can imagine, this can be a very tricky thing to do, as you can see from the code snippet pictured above. Every single image, link, color, shadow, EVERYTHING that you see on a website is coded in very strict strings of code. Think that doing your math homework can be confusing when you leave out a decimal point? Leaving out one single underscore symbol in the middle of 5,000 lines of coding can render a website unviewable. The frustrating thing can be when you don't know where in that ocean of code that there is a problem.
The World Wide Web Consortium (W3C) is an international organization of web developers that work together to develop standards for websites. They offer a free tool that web developers can use if they choose too, that allows us to run our coded pages through their "validator". This special tool will identify problems and conflicts within the raw code/syntax of a website, and will let the web developer know where any bad coding is amongst the ocean of code so that we can troubleshoot the problems.
At Rogue1 Web Design, every one of our websites is run through the W3C's code validator multiple times throughout the creation of your website to ensure that there is no errant coding that could disrupt how your site is displayed on viewing device. It takes longer, can be a pain, but is a necessary step that we have to take to get the job done right.
