Website designers may consider it to be good practice to conform to standards. This is usually done via a description specifying what the element is doing. Failure to conform to standards may not make a website unusable or error prone, but standards can relate to the correct layout of pages for readability as well making sure coded elements are closed appropriately. This includes errors in code, more organized layout for code, and making sure IDs and classes are identified properly. Poorly-coded pages are sometimes colloquially called tag soup. Validating via W3C can only be done when a correct DOCTYPE declaration is made, which is used to highlight errors in code. The system identifies the errors and areas that do not conform to web design standards. This information can then be corrected by the user.
