What is HTML validation?
This is the process that analyzes an HTML document in comparison to standard HTML rules, identifying errors and non-standard codes. Web pages are rendered using HTML (Hyper Text Markup Language). As with any language there are rules and standards that should be followed. For example the HTML 4.01 Specification (rules and standards) are available at http://www.w3.org/TR/html4/. You can check the html validation of your web page by entering your url at: http://validator.w3.org/ 7 Benefits of HTML validation 1.
