HTML5 New Elements

New Elements in HTML5

The internet, and the use of the internet, has changed a lot since 1999, when HTML 4.01 became a standard.

Today, several elements in HTML 4.01 are obsolete, never used, or not used the way they were intended. All those elements are removed or re-written in HTML5.

To better handle today’s internet needs, HTML5 has also included new elements for drawing graphics, displaying media content, for better page structure and better form handling, and several new APIs for drag and drop, for finding your geological location, for storing local data, and more.

Below is a list of the new HTML elements, introduced by HTML5, and a description of what they are used for.
