Robert Nyman http://robertnyman.com/html-validator/ has written an HTML Validator extension for Google Chrome. It can be used to check your code to make sure it is valid and will display correctly on all devices.
This video shows how to use the validator as well as several common mistakes (and the resulting error messages) that new HTML programmers make.
