The "Change on Scroll" Sticky Navbar

An elegant and modern navbar that starts transparent over a hero image and seamlessly transforms into a solid, opaque bar with a shadow as the user scrolls down the page. This provides a clean, impressive look for landing pages while ensuring navigation remains legible and accessible over regular content.

• Transparent to Solid Transition — JavaScript detects the scroll position. When the user scrolls past the hero section, a class is added to the navbar, triggering smooth CSS transitions for background color, text color, and box-shadow.
• Fixed Positioning — Uses position: fixed to remain at the top of the viewport at all times, which is ideal for an overlay effect on a hero section.
• High Readability: In its initial transparent state, text is white with a subtle shadow to ensure it's readable over a variety of hero images. In its solid state, text becomes dark for high contrast.
• Smooth Animations: All state changes are animated with the CSS transition property for a polished, professional feel.
• Fully Responsive: The effect and layout work perfectly on all screen sizes, collapsing into a standard hamburger menu on mobile.

Coding Best Practices

• CSS custom properties (variables) are used for easy theme customization (colors, fonts).
• The code is appropriately commented to explain the purpose of each section.
• A tiny, efficient JavaScript snippet is used for the mobile menu toggle, as it is the most accessible and modern method (arguably superior to the older "checkbox hack").
