<header><h1>spellcheck</h1></header><div class="section-content"><p>The <code>spellcheck</code> <a href="../global_attributes">global attribute</a> is an <a href="https://developer.mozilla.org/en-US/docs/Glossary/Enumerated">enumerated</a> attribute that defines whether the element may be checked for spelling errors.</p></div>

<iframe class="interactive is-tabbed-shorter-height" height="200" src="https://interactive-examples.mdn.mozilla.net/pages/tabbed/attribute-spellcheck.html" title="MDN Web Docs Interactive Example" loading="lazy"></iframe> <p>It may have the following values:</p> <ul> <li>empty string or <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>.</p> <p>This attribute is merely a hint for the browser: browsers are not required to check for spelling errors. Typically non-editable elements are not checked for spelling errors, even if the <code>spellcheck</code> attribute is set to <code>true</code> and the browser supports spellchecking.</p>

<p> Using spellchecking can have consequences for users' security and privacy. The specification does not regulate <em>how</em> spellchecking is done and the content of the element may be sent to a third party for spellchecking results (see <a href="https://www.otto-js.com/news/article/chrome-and-edge-enhanced-spellcheck-features-expose-pii-even-your-passwords" target="_blank">enhanced spellchecking and "spell-jacking"</a>). </p> <p>You should consider setting <code>spellcheck</code> to <code>false</code> for elements that can contain sensitive information.</p>
