<p> <strong><code>inherit</code></strong> 关键字使得元素获取其父元素的<a href="/zh-CN/docs/Web/CSS/computed_value">计算值</a>。它可以应用于任何CSS属性，包括CSS简写 {{cssxref("all")}}。</p>

<p>对于继承属性，inherit 关键字只是增强了属性的默认行为，只有在重载(overload)其它规则的时候被使用。对于非继承属性，inherit 这指定的行为通常没有多大意义，一般使用使用 {{cssxref("initial")}} 或 {{cssxref("unset")}} 作为替代。</p>

<p>继承始终来自文档树中的父元素，即使父元素不是包含块。</p>

<pre class="brush: css">/* 设置二级标题的颜色为绿色 */
h2 { color: green; }

/* ...but leave those in the sidebar alone so they use their parent's color */
#sidebar h2 { color: inherit; }
</pre>

<p>在下面这个例子中，如果sidebar 中<code>h2</code>元素的div匹配下面的规则的话，颜色会变成蓝色。</p>

<pre class="brush: css">div#current { color: blue; }
</pre>

 <li>Use {{cssxref("initial")}} to set a property to its initial value.</li>
 <li>Use {{cssxref("unset")}} to set a property to its inherited value if it inherits, or to its initial value if not.</li>
 <li>Use {{cssxref("revert")}} to reset a property to the value established by the user-agent stylesheet (or by user styles, if any exist).</li>
 <li>The {{cssxref("all")}} property lets you reset all properties to their initial, inherited, reverted, or unset state at once.</li>
