<p>作为一个外观属性，它也可以直接用作一个CSS样式表内部的属性。</p>

 <dt>&lt;dasharray&gt;</dt>
 <dd>它是一个<span><a href="/en/SVG/Content_type#Length" title="en/SVG/Content_type#Length">&lt;length&gt;</a>和</span><a href="/en/SVG/Content_type#Percentage" title="en/SVG/Content_type#Percentage">&lt;percentage&gt;</a>数列，数与数之间用逗号或者空白隔开，指定短划线和缺口的长度。如果提供了奇数个值，则这个值的数列重复一次，从而变成偶数个值。因此，<strong>5,3,2</strong>等同于<strong>5,3,2,5,3,2</strong>。</dd>
