I need a focused functionality boost for my existing website. The design and content need update—what I’m looking for is a simple, reliable way to make the site more engaging through interactive features. Scope • Build and embed one or two lightweight interactive elements (for example, a custom form or quiz) that blend seamlessly with the current layout. • Ensure the feature is responsive, loads quickly, and works across modern browsers and mobile devices. • Provide brief instructions so I can edit questions or form fields later without touching code. Tech stack is flexible; vanilla JavaScript, a small React component, or a PHP-based snippet are all acceptable as long as the final code is clean and well-commented. Please share a quick note on your relevant experience—links to live sites or repos that show similar interactive work are ideal. I’m aiming for a straightforward implementation rather than a full rebuild, so concise proposals are appreciated.
