353: </dl><p>The <code><a href="#the-mark-element">mark</a></code> element <a href="rendering.html#represents">represents</a> a run of
354: text in one document marked or highlighted for reference purposes,
355: due to its relevance in another context. When used in a quotation or
356: other block of text referred to from the prose, it indicates a
357: highlight that was not originally present but which has been added
358: to bring the reader's attention to a part of the text that might not
359: have been considered important by the original author when the block
360: was originally written, but which is now under previously unexpected
361: scrutiny. When used in the main prose of a document, it indicates a
362: part of the document that has been highlighted due to its likely
1.85 mike 363: relevance to the user's current activity.</p>
364:
365: <div class="example">
1.1 mike 366: <p>This example shows how the <code><a href="#the-mark-element">mark</a></code> element can be used
367: to bring attention to a particular part of a quotation:</p>
368: <pre><p lang="en-US">Consider the following quote:</p>
369: <blockquote lang="en-GB">
370: <p>Look around and you will find, no-one's really
371: <mark>colour</mark> blind.</p>
372: </blockquote>
373: <p lang="en-US">As we can tell from the <em>spelling</em> of the word,
374: the person writing this quote is clearly not American.</p></pre>
375: <p>(If the goal was to mark the element as misspelt, however, the
376: <code><a href="the-u-element.html#the-u-element">u</a></code> element, possibly with a class, would be more
377: appropriate.)</p>
1.85 mike 378: </div>
379:
380: <div class="example">
1.1 mike 381:
382: <p>Another example of the <code><a href="#the-mark-element">mark</a></code> element is highlighting
383: parts of a document that are matching some search string. If
384: someone looked at a document, and the server knew that the user was
385: searching for the word "kitten", then the server might return the
386: document with one paragraph modified as follows:</p>
387:
388: <pre><p>I also have some <mark>kitten</mark>s who are visiting me
389: these days. They're really cute. I think they like my garden! Maybe I
390: should adopt a <mark>kitten</mark>.</p></pre>
391:
1.85 mike 392: </div>
393:
394: <div class="example">
1.1 mike 395:
396: <p>In the following snippet, a paragraph of text refers to a
397: specific part of a code fragment.</p>
398:
399: <pre><p>The highlighted part below is where the error lies:</p>
400: <pre><code>var i: Integer;
401: begin
402: i := <mark>1.1</mark>;
403: end.</code></pre></pre>
404:
405: <p>This is separate from <em>syntax highlighting</em>, for which
406: <code><a href="the-span-element.html#the-span-element">span</a></code> is more appropriate. Combining both, one would
407: get:</p>
408:
409: <pre><p>The highlighted part below is where the error lies:</p>
410: <pre><code><span class=keyword>var</span> <span class=ident>i</span>: <span class=type>Integer</span>;
411: <span class=keyword>begin</span>

417: <div class="example">
1.1 mike 418:
419: <p>This is another example showing the use of <code><a href="#the-mark-element">mark</a></code> to
420: highlight a part of quoted text that was originally not
421: emphasized. In this example, common typographic conventions have
422: led the author to explicitly style <code><a href="#the-mark-element">mark</a></code> elements in
423: quotes to render in italics.</p>
424:
425: <pre><article>
426: <style scoped>
427: blockquote mark, q mark {
428: font: inherit; font-style: italic;
429: text-decoration: none;
430: background: transparent; color: inherit;
431: }
432: .bubble em {
433: font: inherit; font-size: larger;
434: text-decoration: underline;
435: }
436: </style>
437: <h1>She knew</h1>
438: <p>Did you notice the subtle joke in the joke on panel 4?</p>
439: <blockquote>
440: <p class="bubble">I didn't <em>want</em> to believe. <mark>Of course
441: on some level I realized it was a known-plaintext attack.</mark> But I
442: couldn't admit it until I saw for myself.</p>
443: </blockquote>
444: <p>(Emphasis mine.) I thought that was great. It's so pedantic, yet it
445: explains everything neatly.</p>
446: </article></pre>
447:
448: <p>Note, incidentally, the distinction between the <code><a href="the-em-element.html#the-em-element">em</a></code>
449: element in this example, which is part of the original text being
450: quoted, and the <code><a href="#the-mark-element">mark</a></code> element, which is highlighting a
451: part for comment.</p>

457: <p>The following example shows the difference between denoting the
458: <em>importance</em> of a span of text (<code><a href="the-strong-element.html#the-strong-element">strong</a></code>) as
459: opposed to denoting the <em>relevance</em> of a span of text
460: (<code><a href="#the-mark-element">mark</a></code>). It is an extract from a textbook, where the
461: extract has had the parts relevant to the exam highlighted. The
462: safety warnings, important though they may be, are apparently not
463: relevant to the exam.</p>

466:
467: <p><mark>A wormhole in normal conditions can be held open for a
468: maximum of just under 39 minutes.</mark> Conditions that can increase
469: the time include a powerful energy source coupled to one or both of
470: the gates connecting the wormhole, and a large gravity well (such as a
471: black hole).</p>
472:
473: <p><mark>Momentum is preserved across the wormhole. Electromagnetic
474: radiation can travel in both directions through a wormhole,
475: but matter cannot.</mark></p>
476:
477: <p>When a wormhole is created, a vortex normally forms.
478: <strong>Warning: The vortex caused by the wormhole opening will
479: annihilate anything in its path.</strong> Vortexes can be avoided when
480: using sufficiently advanced dialing technology.</p>
