Frontend Playground — Small UI Demos

Tiny, focused UI demos to practice fundamentals:

• Forms & validation
• Fetch / pagination
• Responsive layout
• Accessible UI components

Goal: show clean, vanilla HTML/CSS/JS with good UX and accessibility.

Tech & approach

• Stack: HTML, CSS, JavaScript (no framework)
• Style: semantic markup, BEM-ish class names, mobile-first CSS
• A11y: keyboard support, labels, roles/aria where needed
• Perf: no heavy dependencies, images optimized
