<p><strong><code>object-position</code></strong> プロパティは、ボックス内における置換要素の配置を指定します。Areas of the box which aren't covered by the replaced element's object will show the element's background.</p>

<p>You can adjust how the replaced element's object's intrinsic size (that is, its natural size) is adjusted to fit within the element's box using the {{cssxref("object-fit")}} property.</p>
