<div>: The Content Division element
<div>
HTML 元素是流内容的通用容器。它对内容或布局没有影响,直到使用 CSS 以某种方式设置样式(例如,直接将样式应用于它,或者将某种布局模型(如 弹性盒)应用于其父元素)。
¥The <div>
HTML element is the generic container for flow content. It has no effect on the content or layout until styled in some way using CSS (e.g. styling is directly applied to it, or some kind of layout model like Flexbox is applied to its parent element).
Try it
作为 "pure" 容器,<div>
元素本质上并不代表任何东西。相反,它用于对内容进行分组,以便可以使用 class
或 id
属性轻松设置样式,将文档的一部分标记为以不同语言编写(使用 lang
属性),等等。
¥As a "pure" container, the <div>
element does not inherently represent anything. Instead, it's used to group content so it can be easily styled using the class
or id
attributes, marking a section of a document as being written in a different language (using the lang
attribute), and so on.
属性
¥Attributes
该元素包括 全局属性。
¥This element includes the global attributes.
注意:
align
属性已过时;不要再使用它了。相反,你应该使用 CSS 属性或技术(例如 CSS 网格 或 CSS 弹性盒)来对齐和定位页面上的<div>
元素。¥Note: The
align
attribute is obsolete; do not use it anymore. Instead, you should use CSS properties or techniques such as CSS Grid or CSS Flexbox to align and position<div>
elements on the page.
使用说明
无障碍
¥Accessibility
<div>
元素有 generic
的隐含角色,而不是没有。这可能会影响某些 ARIA 组合声明,这些组合声明期望具有特定角色的直接后代元素能够正常运行。
¥The <div>
element has an implicit role of generic
, and not none. This may affect certain ARIA combination declarations that expect a direct descendant element with a certain role to function properly.
示例
一个简单的例子
一个样式化的例子
¥A styled example
此示例通过使用 CSS 将样式应用到 <div>
来创建阴影框。请注意使用 <div>
上的 class
属性将名为 "shadowbox"
的样式应用到元素。
¥This example creates a shadowed box by applying a style to the <div>
using CSS. Note the use of the class
attribute on the <div>
to apply the style named "shadowbox"
to the element.
HTML
<div class="shadowbox">
<p>Here's a very interesting note displayed in a lovely shadowed box.</p>
</div>
CSS
.shadowbox {
width: 15em;
border: 1px solid #333;
box-shadow: 8px 8px 5px #444;
padding: 8px 12px;
background-image: linear-gradient(180deg, #fff, #ddd 40%, #ccc);
}
