  5. Guiding Principles for HTML5 • New features should be based on HTML, CSS, DOM, and JavaScript • Reduce the need for external plugins (like Flash) • Better error handling • More markup to replace scripting • HTML5 should be device independent • The development process should be visible to the public

  10. New Features: Web Storage • Two new objects to save data: • localStorage - stores data with no time limit • sessionStorage - stores data for one session • localStorage • Data stored till cleared programmatically by JS • Or browser cache cleared. • accessible only from the domain that initially stored the data. • sessionStorage • accessible only from the page that initially stored the data.
