Validation and Checkers
Validation and checkers go hand in hand when it comes to the World Wide Web. Validation is when you check an HTML code to see if it complies with a formatted definition.
Checkers can also describe this process. Validation is a complicated program to use; therefore, checkers are used more frequently. You can start with checkers and move up to validators once you get used to the process. Sites can be found online that can set you up with either one of these programs so that you can check websites on your own.
