Revision 720673 of spellcheck

<p class="note">{{HTMLSidebar("Global_attributes")}}{{SeeCompatTable}}</p>
<p>The <strong>spellcheck</strong> <a href="/en-US/docs/Web/HTML/Global_attributes">global attribute</a> is an enumerated attribute defines whether the element may be checked for spelling errors. It may have the following values:</p>
<ul>
 <li><code>true</code>, which indicates that the element should be, if possible, checked for spelling errors;</li>
 <li><code>false</code>, which indicates that the element should not be checked for spelling errors.</li>
</ul>
<p>If this attribute is not set, its default value is element-type and browser-defined. This default value may also be <em>inherited</em>, which means that the element content will be checked for spelling errors only if its nearest ancestor has a <em>spellcheck</em> state of <code>true</code>.<br />
 <br />
 You can consult <a href="/en/HTML/Controlling_spell_checking_in_HTML_forms" title="en/Controlling spell checking in HTML forms">this article</a> to see a comprehensive example of the use of this attribute.</p>
<p>This attribute is an <em>enumerated</em> one and not a <em>Boolean </em>one. This means that the explicit usage of one of the values <code>true</code> or <code>false</code> is mandatory and that a shorthand like <code>&lt;label spellcheck&gt;Example Label&lt;/label&gt; </code>is not allowed. The correct usage is <code>&lt;label spellcheck="true"&gt;Example Label&lt;/label&gt;</code>.</p>
<p>This attribute is merely a hint for the browser: browsers are not required to be able to check for spelling errors. Typically non-editable elements are not checked for spelling errors, even if the <strong>spellcheck</strong> attribute is set to true and the browser supports spellchecking.</p>
<p>The <em>default value</em> of this attribute is browser and element-dependant:</p>
