XHTML: Why is Validation Important
Why you should make sure that your web pages are validated? Thats exactly what we’re going to answer in this tutorial. Hopefully you’ve heard off XHTML and HTML. HTML is the older coding and XHTML is the new generation of HTML. This is the web standard set by the World Wide Web Consortium (W3C) they set standards for the internet. This tutorial will use references to W3 quite often, so if you haven’t heard of them till now you might want to consider checking them out and seeing the work they do.

What is Validation?
Validation is a process of checking your documents against a formal Standard, such as guidelines published by the World Wide Web Consortium (W3C) for HTML and XML-derived Web pages. Consider Validation like Microsoft word for a moment. Imagine you’ve wrote a 5000 words essay and any spelling mistakes made would mark you down for that essay. To make sure this doesn’t happen you would use a spell checker to check grammar and spelling, you could also check it yourself, but a spell checker is more accurate. Validation is like a spell checker it is a precise process and is very reliable. Precise because it deals with languages in the ways browsers work as well as specific machine langauges.

Why Validate?
You should validate your web pages because by doing this, you know you are following web standards set by W3, validation in many people’s eyes is a real pain. This shouldn’t be the case. Validation is a very important factors of you code and design, I wouldn’t be able to thank it enough because it can say you from serious errors occurring in your code as well spot potential issues that don’t necessarily harm anything but pose a threat. Validation also shows to your visitors that you have taken care in coding your web pages and show that you follow standards set.

Do I have to follow standards?
You are not forced to validate your web pages but, by not validating your web pages your not correctly coding and you could potentially coding bad mark up without realizing it. People get confused with the fact that W3 set recommendations. They don’t make them, they make recommendations, they are however dedicated in setting standards for the world and do a damn good job.
