240: here is used to describe how to interpret documents.</p><p>A <dfn id="paragraph">paragraph</dfn> is typically a run of <a href="dom.html#phrasing-content">phrasing
241: content</a> that forms a block of text with one or more sentences
242: that discuss a particular topic, as in typography, but can also be
243: used for more general thematic grouping. For instance, an address is
244: also a paragraph, as is a part of a form, a byline, or a stanza in a
245: poem.</p><div class="example">
246:
247: <p>In the following example, there are two paragraphs in a
248: section. There is also a heading, which contains phrasing content
249: that is not a paragraph. Note how the comments and
250: <a href="dom.html#inter-element-whitespace">inter-element whitespace</a> do not form paragraphs.</p>
251:
252: <pre><section>
253: <h1>Example of paragraphs</h1>
254: This is the <em>first</em> paragraph in this example.
255: <p>This is the second.</p>
256: <!-- This is not a paragraph. -->
257: </section></pre>
258:
259: </div><p>Paragraphs in <a href="dom.html#flow-content">flow content</a> are defined relative to
260: what the document looks like without the <code><a href="text-level-semantics.html#the-a-element">a</a></code>,
261: <code><a href="text-level-semantics.html#the-ins-element">ins</a></code>, <code><a href="text-level-semantics.html#the-del-element">del</a></code>, and <code><a href="the-canvas-element.html#the-map-element">map</a></code> elements
262: complicating matters, since those elements, with their hybrid
263: content models, can straddle paragraph boundaries, as shown in the
264: first two examples below.</p><p class="note">Generally, having elements straddle paragraph
265: boundaries is best avoided. Maintaining such markup can be
266: difficult.</p><div class="example">
267:
268: <p>The following example takes the markup from the earlier example
269: and puts <code><a href="text-level-semantics.html#the-ins-element">ins</a></code> and <code><a href="text-level-semantics.html#the-del-element">del</a></code> elements around some
270: of the markup to show that the text was changed (though in this
271: case, the changes admittedly don't make much sense). Notice how
272: this example has exactly the same paragraphs as the previous one,
273: despite the <code><a href="text-level-semantics.html#the-ins-element">ins</a></code> and <code><a href="text-level-semantics.html#the-del-element">del</a></code> elements —
274: the <code><a href="text-level-semantics.html#the-ins-element">ins</a></code> element straddles the heading and the first
275: paragraph, and the <code><a href="text-level-semantics.html#the-del-element">del</a></code> element straddles the boundary
276: between the two paragraphs.</p>

286: <code><a href="semantics.html#the-p-element">p</a></code> elements.</p><p class="note">The <code><a href="semantics.html#the-p-element">p</a></code> element can be used to wrap
287: individual paragraphs when there would otherwise not be any content
288: other than phrasing content to separate the paragraphs from each
289: other.</p><div class="example">
290:
291: <p>In the following example, the link spans half of the first

323: <p>It is possible for paragraphs to overlap when using certain
324: elements that define fallback content. For example, in the
325: following section:</p>
326:
327: <pre><section>
328: <h1>My Cats</h1>
329: You can play with my cat simulator.
330: <object data="cats.sim">
331: To see the cat simulator, use one of the following links:
332: <ul>
333: <li><a href="cats.sim">Download simulator file</a>
334: <li><a href="http://sims.example.com/watch?v=LYds5xY4INU">Use online simulator</a>
335: </ul>
336: Alternatively, upgrade to the Mellblom Browser.
337: </object>
338: I'm quite proud of it.
339: </section></pre>
340:
341: <p>There are five paragraphs:</p>
342:
343: <ol class="brief"><li>The paragraph that says "You can play with my cat
344: simulator. <i title="">object</i> I'm quite proud of it.", where
345: <i title="">object</i> is the <code><a href="text-level-semantics.html#the-object-element">object</a></code> element.</li>
346:
347: <li>The paragraph that says "To see the cat simulator, use one of
348: the following links:".</li>
349:
350: <li>The paragraph that says "Download simulator file".</li>
351:
352: <li>The paragraph that says "Use online simulator".</li>
353:
354: <li>The paragraph that says "Alternatively, upgrade to the Mellblom Browser.".</li>
355:
356: </ol><p>The first paragraph is overlapped by the other four. A user
357: agent that supports the "cats.sim" resource will only show the
358: first one, but a user agent that shows the fallback will
359: confusingly show the first sentence of the first paragraph as
360: if it was in the same paragraph as the second one, and will show
361: the last paragraph as if it was at the start of the second sentence
362: of the first paragraph.</p>
363:
364: <p>To avoid this confusion, explicit <code><a href="semantics.html#the-p-element">p</a></code> elements can be
365: used.</p>
