Represents a run of text that is contextually-important for some reason, such as text that has been marked or highlighted.
The following example shows the difference between denoting the importance of a span of text (strong) as opposed to denoting the relevance of a span of text (mark). It is an extract from a textbook, where the extract has had the parts relevant to the exam highlighted. The safety warnings, important though they may be, are not relevant to the exam.
<h3>Wormhole Physics Introduction</h3> <p><mark>A wormhole in normal conditions can be held open for a maximum of just under 39 minutes.</mark> Conditions that can increase the time include a powerful energy source coupled to one or both of the gates connecting the wormhole, and a large gravity well (such as a black hole).</p> <p><mark>Momentum is preserved across the wormhole. Electromagnetic radiation can travel in both directions through a wormhole, but matter cannot.</mark></p> <p>When a wormhole is created, a vortex normally forms. <strong>Warning: The vortex caused by the wormhole opening will annihilate anything in its path.</strong> Vortexes can be avoided when using sufficiently advanced dialing technology.</p> <p><mark>An obstruction in a gate will prevent it from accepting a wormhole connection.</mark></p>
This example uses mark to indicate the "current" link.

The mark element is a phrasing-level element. It must not contain block-level elements, but it can contain other phrasing-level elements.
The mark element denotes the relevance of a span of text. By default, most browsers render it in black text on a yellow background, but you can change that with CSS.
When used in the main prose of a document, the mark element indicates a part of the document that has been highlighted. When used in a quotation or other block of text (such as an aside), it indicates a highlight that was not originally present but which has been added to bring the reader's attention to a part of the text. For example, the following are valid uses for the mark element:
- Bring attention to a particular string of text.
- Highlight parts of document that match a search string.
- Enable body text to refer to a specific part of a quotation or code fragment.
Windows Internet Explorer 9. The mark element is only supported for webpages displayed in IE9 Standards mode. For more information, see Defining Document Compatibility.
