<p id="Summary"><br>
 <code>counter-reset</code> 属性用于将 <a href="/en-US/docs/CSS_Counters">CSS计数器</a> 重置为制定值</p>

<p>{{EmbedInteractiveExample("pages/css/counter-reset.html")}}</p>

<div class="blockIndicator note">
<p>注意:计数器的值能够通过 CSS 属性 {{cssxref("counter-increment")}} 控制递增或递减。</p>
</div>

<h2 id="Syntax" name="Syntax">语法</h2>

<pre class="brush:css">/* Set counter-name to 0 */
counter-reset: counter-name;

/* Set counter-name to -1 */
counter-reset: counter-name -1;

/* Set counter1 to 1, and counter2 to 4 */
counter-reset: counter1 1 counter2 4;

/* Cancel any reset that could have been set in less specific rules */
counter-reset: none;

/* Global values */
counter-reset: inherit;
counter-reset: initial;
counter-reset: unset;
</pre>

<p><code>counter-reset</code> 属性可以指定为以下之一:</p>

<ul>
 <li><code>&lt;自定义 ID&gt; [&lt;数值&gt;]</code>。您可以指定任意数量的计数器进行重置,每个名称或“名称-数字”对之间用空格分隔。</li>
 <li>特殊值 <code>none</code></li>
</ul>

<h3 id="Values" name="Values">可选值</h3>

<dl>
 <dt>{{cssxref("custom-ident", "&lt;custom-ident&gt;")}}</dt>
 <dd>要递增的计数器的名称。</dd>
</dl>

<div class="blockIndicator note">
<p>该名称由不区分大小写的字母 a 到 z,数字 0 到 9,下划线(_)和 / 或短划线( - )的组合组成,并且第一个非破折号字符必须是一个字母(即,在它的开头没有数字,即使前面有破折号)。此外,在标识符的开头禁止使用两个破折号。在任何案例组合中都不能是 none,unset,initial 或 inherit。</p>
</div>

<dl>
 <dt>{{cssxref("&lt;integer&gt;")}}</dt>
 <dd>每次出现元素时将计数器重置为的值。如果不指定,则默认为 <code>0</code></dd>
 <dt><code>none</code></dt>
 <dd>该关键字表示不执行计数器重置。它可用于重置隐藏在不太具体的规则中定义的计数器。你可以指定要根据需要重置的计数器,每个计数器用空格分隔。</dd>
