Bootstrap 5：网格示例

目录

    显示目录

下面我们收集了一些 Bootstrap 5 网格布局的示例。

三等柱

在指定数量的元素上使用 .col 类，Bootstrap 将识别有多少个元素（并创建等宽列）。在下面的示例中，我们使用三个 col 元素，每个元素的宽度为 33.33%。

col
col
col

例子

<div class="row">
  <div class="col">col</div>
  <div class="col">col</div>
  <div class="col">col</div>
</div>

<div class="container-fluid mt-3">
  <h2>Three Equal Columns</h2>
  <p>Use the .col class on a specified number of elements and Bootstrap will recognize how many elements there are (and create equal-width columns). In the example below, we use three col elements, which gets a width of 33.33% each.</p>
  <div class="row">
    <div class="col bg-success">.col</div>
    <div class="col bg-warning">.col</div>
    <div class="col bg-success">.col</div>
  </div>
</div>

</body>
</html>

使用数字的三个相等的列

您还可以使用数字来控制列宽。只需确保总和等于或小于 12（不需要使用所有 12 个可用列）：

col-4
col-4
col-4

例子

<div class="row">
  <div class="col-4">col-4</div>
  <div class="col-4">col-4</div>
  <div class="col-4">col-4</div>
</div>

<body>

<div class="container-fluid mt-3">
  <h2>Three Equal Columns</h2>
  <p>You can also use numbers to control the column width. Just make sure that the sum always adds up to 12:</p>
  <div class="row">
    <div class="col-4 bg-success">.col-4</div>
    <div class="col-4 bg-warning">.col-4</div>
    <div class="col-4 bg-success">.col-4</div>
  </div>
</div>

</body>
</html>

三个不等柱

要创建不相等的列，您必须使用数字。以下示例将创建 25%/50%/25% 分割：

col-3
col-6
col-3

例子

<div class="row">
  <div class="col-3">col-3</div>
  <div class="col-6">col-6</div>
  <div class="col-3">col-3</div>
</div>

<div class="container-fluid mt-3">
  <h2>Three Unequal Columns</h2>
  <p>To create unequal columns, you have to use numbers. The following example will create a 25%/50%/25% split:</p>
  <div class="row">
    <div class="col-3 bg-success">.col-3</div>
    <div class="col-6 bg-warning">.col-6</div>
    <div class="col-3 bg-success">.col-3</div>
  </div>
</div>

</body>
</html>

设置一列宽度

但是，仅设置一列的宽度就足够了，并且让同级列在其周围自动调整大小。以下示例将创建 25%/50%/25% 分割：

col
col-6
col

例子

<div class="row">
  <div class="col">col</div>
  <div class="col-6">col-6</div>
  <div class="col">col</div>
</div>

<div class="container-fluid mt-3">
  <h2>Three Unequal Columns</h2>
  <p>It is enough to only set the width of one column, and have the sibling columns automatically resize around it. The following example will create a 25%/50%/25% split:</p>
  <div class="row">
    <div class="col bg-success">.col</div>
    <div class="col-6 bg-warning">.col-6</div>
    <div class="col bg-success">.col</div>

如果其中一列比另一列高（由于文本或 CSS 高度），其余列将遵循：

Lorem ipsum dolor sit amet, cibo sensibus interesset no sit. Et dolor possim volutpat qui. No malis tollit iriure eam, et vel tale zril blandit, rebum vidisse nostrum qui eu. No nostrud dolorem legendos mea, ea eum mucius oporteat platonem.Eam an case scribentur, ei clita causae cum, alia debet eu vel.

响应式课程

Bootstrap 5 网格系统有五个类：

  • .col-（超小型设备 - 屏幕宽度小于 576 像素）

  • .col-sm-（小型设备 - 屏幕宽度等于或大于 576 像素）

  • .col-md-（中型设备 - 屏幕宽度等于或大于 768 像素）

  • .col-lg-（大型设备 - 屏幕宽度等于或大于 992 像素）

  • .col-xl-（超大设备 - 屏幕宽度等于或大于 1200 像素）

  • .col-xxl-（xxl 设备 - 屏幕宽度等于或大于 1400 像素）

可以组合上面的类来创建更加动态和灵活的布局。

提示：每个类都会按比例放大，因此如果您希望为 sm 和 设置相同的宽度md，只需指定sm即可。

水平堆叠

col-sm-9
col-sm-3
col-sm
col-sm
col-sm

以下示例演示如何创建一个列布局，该布局在超小型设备上开始堆叠，然后在较大设备（sm、md、lg 和 xl）上变为水平：

例子

<div class="row">
  <div class="col-sm-9">col-sm-9</div>
  <div class="col-sm-3">col-sm-3</div>
</div>
<div class="row">
  <div class="col-sm">col-sm</div>
  <div class="col-sm">col-sm</div>
  <div class="col-sm">col-sm</div>

无排水沟

要更改列之间的装订线（额外空间），请使用任何 .g-1|2|3|4|5 类 (.g-4 是默认值）。

要完全删除装订线，请使用 .g-0：
