Bulma - 面包屑

描述

.breadcrumb 类是定义面包屑组件所必需的，.is-active 类可用于显示一个特定的活动页面。

默认的 .breadcrumb 类对齐到左侧。你可以通过将 .breadcrumb 类与 is-centered 类（用于居中对齐）和 is-right 类（用于右对齐）相结合来对齐面包屑容器。

以下示例介绍了如何显示面包屑（在 nav 标记中使用 breadcrumb 类）以及页面中元素的对齐方式 −

图标

.breadcrumb 类可用于与 Font Awesome 图标一起使用，并且还可与附加的分隔符类（例如 has-arrow-separator、has-bullet-separator、has-dot-separator、has-succeeds-separator 类）相结合。

以下示例演示了如何使用上述附加的分隔符类连同 .breadcrumb 类容器以及图标 −
