<div>{{HTMLSidebar("Global_attributes")}}</div>

<p><strong>style</strong> <a href="/en-US/docs/Web/HTML/Global_attributes">全局属性</a> 包含应用到元素的 <a href="/en-US/docs/Web/CSS">CSS</a> 样式声明。要注意样式最好定义在单独的文件中。这个属性以及 {{HTMLElement("style")}} 元素的主要目的是快速装饰。例如用于测试目的。</p>

<div class="note">
<p><strong>用法注解：</strong>这个属性不能用于传递语义信息。即使所有样式都移除了，页面也应该保留正确语义。通常它不应用于隐藏不相关的信息；这应该使用 <a href="#attr-hidden"><strong>hidden</strong></a> 属性来实现。</p>
