Tips for HTML5, part 4: New tags
Continuing with this series of brief posts about the future of HTML (and what our students will need to know about it), I’m going to list the HTML tags that are new in HTML5. These are subject to change, of course, because the specification isn’t finished yet.
For short definitions of all valid tags for HTML5 tags, see the one-page HTML 5 Tag Reference at W3schools.
<canvas> See this post for an introduction.
<command> See note 1 below.
<details> See note 1 below.
<embed> See note 2 below.
<menu> See note 1 below.
<summary> See note 1 below.
<video> See this post for details.
Note 1: These four tags are categorized as “interactive elements,” explained further at WHATWG.
Note 2: The <embed> tag is new in HTML5, even though we have used an <embed> tag for many years. Its attributes are src, type, height, and width. It is used for plug-in content, but it is different from the new <video> and <audio> tags. The <object> tag does not go away. Both <embed> and <object> use MIME types.
