Header

Headers play a crucial role in structuring content, providing clear navigation and enhancing readability by organizing information into distinct, easily digestible sections for users.

Overview

Usage

When to use this component?

The header component should be used on all pages of the website to provide a consistent navigation experience for users. It serves as a central hub for accessing key sections of the site, ensuring users can easily locate important features or content regardless of their current location within the website.

How it works

The header component typically includes three key sections: a branding area, navigation tabs, and interactive controls. The branding area prominently features logos for clear organizational identity. Navigation tabs provide quick access to different sections, with a visual indicator for the active tab. Interactive controls include a search bar for content discovery, an accessibility icon for usability features, a language toggle for switching between languages, and a login button for user authentication. The header is designed to adapt fluidly to different screen sizes, ensuring clarity, usability, and accessibility across devices.
