Bootstrap 5 Navigation Components: Implementation of Tabs and Breadcrumb Navigation

To use Bootstrap 5 navigation components, you first need to include its CSS and JS files (including Popper.js) in your HTML. Core components include tab navigation and breadcrumb navigation. **Tab Navigation (Tabs)** is used for categorizing content switching: Implemented via `.nav-tabs` (or `.nav-pills` for pill-shaped navigation), it requires wrapping navigation items with `.nav`. Navigation buttons (`nav-link`) are associated with content panels using `data-bs-toggle="tab"` and `data-bs-target`. Content areas are wrapped in `.tab-content` containing `.tab-pane`, where `fade` and `active` classes control transitions and default display. Accessibility attributes are supported to enhance user experience. **Breadcrumb Navigation** displays page hierarchy: Wrapped with the `.breadcrumb` class and an ordered list, each level is represented by `.breadcrumb-item`, with `.active` marking the current page. The default separator can be customized via CSS (e.g., `content: "›"`). It is pure HTML/CSS and does not require JavaScript. **Summary**: Tabs rely on JS for content switching and are suitable for categorized content; breadcrumbs are static and ideal for hierarchical display. Both support accessibility attributes. Bootstrap 5 provides rich extensions (e.g., pill-style, custom separators), enabling quick implementation.
