New Elements in HTML5
The internet has changed a lot since HTML 4.01 became a standard in 1999.
Today, some elements in HTML 4.01 are obsolete, never used, or not used the way they were intended to. These elements are removed or re-written in HTML5.
To better handle today's internet use, HTML5 includes new elements for better structure, better form handling, drawing, and for media content.
