Bulma - 容器和级别

描述

Bulma 使用 容器 来表示基本布局元素并包装网站内容。容器 类在不同设备上的宽度值如下 −

• 桌面 的最大宽度为 960px。

• 宽屏 的最大宽度为 1152px。

• 全高清 的最大宽度为 1344px。

让我们创建一个 容器 类的简单示例 −

注意 −调整编码地面输出窗口的大小，以查看根据窗口大小发生的变化。

级别

Bulma 包含水平级别，用于指定左侧和右侧的级别。level-left 类指定左侧的元素，level-right 类指定右侧的元素。您可以使用 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 − 您可以使项目在 level 容器中居中。

• 移动级别 −如果要在移动设备上水平显示项目，请在 level 容器中使用 is-mobile 修饰符。

让我们使用上述级别类型为 level 创建一个简单的示例，如下所示 −

注意 − 调整编码地面输出窗口的大小，以查看根据窗口大小发生的变化。
