<p><strong><code>HTMLStyleElement</code></strong> 接口表示 {{HTMLElement("style")}} 元素。它从 {{domxref("HTMLElement")}} 和 {{domxref("LinkStyle")}} 中继承属性和方法。</p>

<p>这个接口不允许修改包含其中的CSS（大多数情况下）。如果需要修改CSS，前往<a href="https://developer.mozilla.org/zh-CN/docs/Web/API/CSS_Object_Model/Using_dynamic_styling_information">关于使用动态样式的信息</a>查看在DOM中用于修改特定CSS属性的对象。</p>
