Design the primary site header to carry brand, navigation, search, and
Information Architecture should include brand/logo, global navigation, search entry, and a primary call-to-action (CTA) like ‘Explore Countries’. This ensures users can quickly find what they’re looking for.
Secondary links – such as ‘About’ and ‘Contact’ – should be presented in a condensed utility bar when sufficient space is available. This maintains a clean and organized header.
Tablet: logo + hamburger, inline search toggle; CTA condensed to icon+
For tablet devices, the header will feature a logo alongside a hamburger menu for navigation. An inline search toggle provides convenient access to the search functionality.
The CTA should be condensed into an icon, maintaining visual clarity and reducing clutter on smaller screens. Height targets are 72px desktop, 64px tablet, and 56px mobile.
ARIA landmarks: <header role="banner"> , nav role="navigation" ,
Keyboard navigation should be implemented with a logical tab order, accompanied by focus-visible rings to indicate interactive elements. Escape key functionality closes menus.
Ensure sufficient contrast between text and icons against the background to meet WCAG 2.1 AA accessibility guidelines.
Frequently asked questions
What are the performance considerations for the header component?
Performance & Delivery - Optimizing assets and minimizing render-blocking scripts is key to a fast loading experience.
How should I implement critical CSS for the above-the-fold content in the header?
Use inline critical CSS for above-the-fold content; lazy-load heavy assets. Employ an SVG logo, set explicit dimensions to avoid Cumulative Layout Shift (CLS), and avoid large drop-shadows – prefer subtle shadow-1 and border effects.
What are the copyright considerations for displaying AI usage data by countries in the header?
© 2024 AI Usage by Countries. The Header component is responsible for this display.
