The problem many sites face
Many sites use third-party slider libraries that seem easy at first but: - Add unnecessary JavaScript and slow page loads. - Are hard to style to match your brand. - Often lack basic accessibility for keyboard or screen-reader users.
What you want instead is a small, controlled component that does one job well: showcase testimonials and encourage clicks.
The simple solution (what a lightweight slider looks like)
At a high level, a lightweight React slider includes: 1. A small data file (array of testimonial objects: name, text, role, avatar). 2. A component that stores the current slide index (this is just a small piece of state). 3. Next/Previous controls and optional dots for quick navigation. 4. CSS for layout, responsiveness, and subtle transitions.
This approach avoids heavy dependencies, keeps the bundle small, and gives you full control over styling and behavior.
Quick implementation plan (for your developer or contractor)
Use this checklist when building or reviewing a slider: 1. Data: Keep testimonials in src/data or loaded from your CMS/API; include a unique id for each item. 2. Component: Use a functional React component with a single piece of state for the active index. Update the index with “next” and “prev” logic that wraps around. 3. Controls: Add accessible buttons (aria-labels) and optional indicators. Ensure controls are large enough for mobile. 4. Styles: Use CSS Modules or scoped styles so the slider doesn’t affect the rest of the page. 5. Performance: No heavy libraries; avoid unnecessary re-renders and lazy-load avatars.
Benefits of this plan: - Faster page load times - Easier customization to match brand - Smaller maintenance burden
Design, performance and accessibility tips
Here are quick, practical rules to follow: - Keep testimonial text concise (1–3 short sentences) so cards don’t break layout. - Use relative units (rem, %) and media queries for responsive layouts. - Add a short fade or slide transition (0.3–0.5s) to make changes feel smooth. - Make all interactive elements keyboard-accessible and include aria-live or announcements for screen readers when the active slide changes. - Prefer local images or a CDN for avatars to reduce load time.
Bullet list of must-dos: - Use unique keys for list items - Pause autoplay on hover/focus if you enable it - Test on real devices and screen sizes - Keep the JS footprint under 10 KB if possible
