<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>

<p>[1] Gecko supported, from version 1.1 to version 1.9.2, which corresponds to Firefox 1.0 to 3.6 included, a different, and prefixed, syntax: <code>-moz-background-origin: padding | border</code>.</p>

<p>[2] Internet Explorer up to version 7 behaves as if there was a <code>background-origin: border-box;</code> Internet Explorer 8 behaves as if it were <code>background-origin: padding-box;</code> which is the regular default value.</p>

<p>[3] Webkit also supports the prefixed version of this proprietary, and in that case, in addition to the current keywords, the alternative synonyms: <code>padding</code>, <code>border</code>, and <code>content</code>.</p>

<p>[4] Konqueror 3.5.4 supports<code> -khtml-background-origin</code>.</p>
