HTML5 Browser Support HTML5 is supported in all modern browsers. In addition, all browsers, old and new, automatically handle unrecognized elements as inline elements. Because of this, you can "teach" older browsers to handle "unknown" HTML elements. You can even teach IE6 (Windows XP 2001) how to handle unknown HTML elements.

This div is bigger (width is also 300px and height is 100px). The two <div> elements above end up with different sizes in the re...
