Bulma - 面包屑

描述

需要使用 .breadcrumb 类来定义面包屑组件，而可以使用 .is-active 类来显示特定的活动页面。

默认的 .breadcrumb 类向左对齐。您可以将 .breadcrumb 类与 is-centered 类组合以居中对齐，并将其与 is-right 类组合以右对齐，从而对齐面包屑容器。

以下示例描述了如何显示面包屑(在 nav 标签中使用 breadcrumb 类)以及页面中元素的对齐方式 −

图标

.breadcrumb 类可与 Font Awesome 图标一起使用，也可与其他分隔符类(如 has-arrow-separator、has-bullet-separator、has-dot-separator、has-succeeds-separator 类)结合使用。

以下示例演示了图标和上述其他分隔符类以及 .breadcrumb 类容器的使用 −
