[Innovation of HTML 5: The beauty of structure]_html/css_WEB-ITnose

Foreword HTML 5 is like a revolution, which is going on vigorously in the post-Web2.0 era. There is no need for me to go into details here about what HTML 5 is. As for the innovation of HTML 5, according to my understanding, it can be summarized as a tag system with clear semantics, rich media support that simplifies complexity, magical local data storage technology, rich animation (canvas) that does not require plug-ins, and powerful API support. .
