Add Background to the Header on Scroll

[rlajous]

Description:

A background color should be dynamically added to the header component to enhance its visibility and improve the readability of navigation links as the page scrolls. This feature will ensure the header remains prominent against varying content backgrounds as the user scrolls through the page.

Expected Behavior:

• Initially, the header should be transparent or have no background color when the page is at the top.
• As the user scrolls down, a background color fades in or instantly appears on the header.
• The background color should be consistent with the website's color scheme and should not obstruct any underlying page content.

Steps to Implement:

1. Add an event listener for the scroll event in the Header component.
2. Determine the scroll threshold at which the background should be added.
3. Use state to toggle a CSS class on the header that applies the background color when the scroll threshold is surpassed.
4. Remove the background color (by toggling the class off) when the user scrolls back to the top of the page.
5. Ensure the transition of the background color is smooth and visually appealing.

Relevant Files:

• Header component (path: components/Header/Header.tsx)
• CSS/SCSS files for dynamic background styling

Additional Notes:

• Test across different browsers and devices to ensure compatibility and responsiveness.
• Consider the performance impact of scroll event handling and optimize as necessary, potentially by debouncing or throttling the event handler.
