1. <meter>
<meter> that represents a scalar measurement within a known range, or a fractional value.
2. <article>
The <article> tag specifies independent, self-contained content.
3. <progress>
The <progress> tag represents the completion progress of a task.
4. <aside>
The <aside> tag defines some content aside from the content it is placed in.
5. <pre>
The <pre> tag defines preformatted text.
6. <canvas>
The <canvas> tag is used to draw graphics, on the fly, via scripting (usually JavaScript).
