justify-content: center;
color: white;
margin-bottom: 10px;
}

border-radius: 50px; /* ⬅️ Fully rounded ends */

🧠 Advanced Tip – Individual Corner Control
You can target each corner separately for custom shapes:
.box {
border-radius: 10px 20px 30px 40px;
/* Top-left → Top-right → Bottom-right → Bottom-left */
}
Or use individual properties:
.box {
border-top-left-radius: 10px;
border-top-right-radius: 20px;
border-bottom-right-radius: 30px;
border-bottom-left-radius: 40px;
}

🎓 Professional Best Practices
Principle Why
Use radius for modernity ✨ Rounded corners feel friendlier and more approachable – use them on cards, buttons, and modals
50% creates circles ⭕ Perfect for avatars – always pair with overflow: hidden to crop content
Pills for CTAs 💊 border-radius: 9999px on buttons gives that "pill" effect – very popular in modern design
Consistent scale 📐 Use a spacing scale (e.g., 4px, 8px, 12px, 16px) for radius values to maintain harmony
Don't over‑round 🛑 Excessive rounding can look toy‑like – keep it subtle for professional projects

🚀 Final Thought: Borders and radii are the jewelry of your UI – small details that make a huge impact. Use them intentionally, and your designs will feel polished, modern, and refined! 💎✨
