<h2 id="摘要">摘要</h2>
<p> <code>background-origin</code> 规定了指定背景图片{{cssxref("background-image")}} 属性的原点位置的背景相对区域.</p>
<p>注意：当使用 {{Cssxref("background-attachment")}} 为fixed时，该属性将被忽略不起作用。</p>
<div class="note">假如<span style="line-height: 1.5;">{{cssxref("background")}}简写中没有设置该值，那么在 background 简写值后指定</span><span style="font-family: courier new,andale mono,monospace; line-height: 1.5;">background-origin，那么后面的值就会覆盖简写值，其实说白了，就是后出现的值会覆盖前面的值。</span></div>
