<h2 id="語法">語法</h2>

<pre class="brush: css no-line-numbers">/* 關鍵字值 */
cursor: pointer;
cursor: auto;

/* URL, with a keyword fallback */
cursor: url(hand.cur), pointer;

/* URL and coordinates, with a keyword fallback */
cursor: url(cursor1.png) 4 12, auto;
cursor: url(cursor2.png) 2 2, pointer;

/* 全域值 */
cursor: inherit;
cursor: initial;
cursor: unset;
</pre>

<p>The <code>cursor</code> property is specified as zero or more <code><a href="#&lt;url>">&lt;url&gt;</a></code> values, separated by commas, followed by a single mandatory <a href="#Keyword values">keyword value</a>. Each <code>&lt;url&gt;</code> should point to an image file. The browser will try to load the first image specified, falling back to the next if it can't, and falling back to the keyword value if no images could be loaded (or if none were specified).</p>

<p>Each <code>&lt;url&gt;</code> may be optionally followed by a pair of space-separated numbers, which represent <code><a href="#&lt;x> &lt;y>">&lt;x&gt;&lt;y&gt;</a></code> coordinates. These will set the cursor's hotspot, relative to the top-left corner of the image.</p>

<p>For example, this specifies two images using <code>&lt;url&gt;</code> values, providing <code>&lt;x&gt;&lt;y&gt;</code> coordinates for the second one, and falling back to the <code>progress</code> keyword value if neither image can be loaded:</p>

<pre class="brush: css">cursor: url(one.svg), url(two.svg) 5 5, progress;</pre>

 <dd>A <code>url(…)</code> or a comma separated list <code>url(…), url(…), …</code>, pointing to an image file. More than one {{cssxref("&lt;url&gt;")}} may be provided as fallbacks, in case some cursor image types are not supported. A non-URL fallback (one or more of the keyword values) <em>must</em> be at the end of the fallback list.
