描述

Bulma 使用容器来表示基本布局元素并封装网站内容。容器类在不同的设备上将具有以下宽度值 -

  • 桌面的最大宽度为 960 像素。

  • 宽屏的最大宽度为 1152 像素。

  • 全高清的最大宽度为 1344 像素。

我们来创建容器类的一个简单示例 -

注意 - 调整编码基础输出窗口大小，以查看根据窗口大小发生的更改。

级别

Bulma 包括水平级别以指定左侧和右侧的级别。level-left 类指定左侧的元素，而level-right 类指定右侧的元素。你可以通过使用level-item 类定义每个单独的元素。

级别包含两种类型的级别。

  • 居中级别 - 你可以在level容器中让项目居中。

  • 移动级别 - 如果你想在移动设备上水平显示项目，则在level容器中使用is-mobile 修饰符。

我们来通过使用上述级别类型创建level的一个简单示例，如下所示 -

注意 - 调整编码基础输出窗口大小，以查看根据窗口大小发生的更改。
