<h2 id="Описание">Описание</h2>

<p>The <strong><code>border-image-outset</code></strong> property describes by what amount the <dfn>border image area</dfn> extends beyond the border box.</p>

<p>Portions of the border image that are rendered outside the border box as a result of this property do not cause scrolling to be triggered. These areas also don't capture or cause mouse events to occur on behalf of the bordered element.</p>
