<p><span class="seoSummary"><strong><code>Element</code></strong> 是一个通用性非常强的基类，所有 {{DOMxRef("Document")}} 对象下的对象都继承自它。这个接口描述了所有相同种类的元素所普遍具有的方法和属性。一些接口继承自 <code>Element</code> 并且增加了一些额外功能的接口描述了具体的行为。</span>例如， {{DOMxRef("HTMLElement")}} 接口是所有 HTML 元素的基本接口，而 {{DOMxRef("SVGElement")}} 接口是所有 SVG 元素的基础。大多数功能是在这个类的更深层级（hierarchy）的接口中被进一步制定的。</p>

<p>在 Web 平台的领域以外的语言，比如 XUL，通过 <code>XULElement</code> 接口，同样也实现了 <code>Element</code> 接口。</p>
