It is very inportant to validate your website because it helps in many ways. From making it load right / the same in all browsers to helping you in the SEO area.
What exactly is validation? It's the process of checking the syntax of your HTML code to find places where you've violated the rules of the language. The official rules for writing HTML are defined by the World Wide Web Consortium (W3C). 
Those rules include strict definitions stating which HTML and tags are legitimate parts of the language, and how you should structure your HTML and CSS documents.
Here i provide some essential tools for validatign your website :
