Designing a great web interface is about making hundreds of small, thoughtful decisions. Here are key principles I follow when building modern, usable web apps.
Interactions
- Keyboard-friendly: Every flow should work with the keyboard. Follow WAI-ARIA patterns.
- Focus clarity: Visible focus rings matter; use
:focus-visibleto avoid distraction. - Touch targets: Hit areas should be ≥24px on desktop, ≥44px on mobile.
- Optimistic updates: Update the UI immediately, provide undo on failure.
- Confirm destructive actions: Ask for confirmation or allow undo.
- Accessible links: Use
<a>for navigation; avoid<div>or<button>for links.
Animations
- Reduce motion support: Honor
prefers-reduced-motion. - GPU-friendly: Animate
opacityandtransformonly. Avoid layout-triggering properties. - Interruptible & input-driven: Animations should respond to user actions and be cancelable.
Layout & Content
- Responsive design: Test mobile, desktop, and wide screens.
- Safe areas: Respect notches and insets.
- Clear states: Design for empty, sparse, dense, and error states.
- Accessible text & icons: Use labels, alt text, and redundant cues for clarity.
- Locale-aware formatting: Handle dates, numbers, and currencies per user locale.
Forms & Inputs
- Labels everywhere: Associate inputs with
<label>. - Smart submission: Keep submit enabled until request starts; show spinner.
- User-friendly validation: Allow typing freely; show inline errors.
- Autocomplete & input types: Use meaningful names and types to improve UX.
Performance & Design
- Efficient rendering: Minimize reflows, batch updates, virtualize large lists.
- Image & font optimization: Preload critical assets, lazy-load the rest.
- Contrast & readability: Ensure sufficient contrast, use layered shadows, and align elements intentionally.
Following these guidelines ensures web interfaces are usable, accessible, and delightful. Every decision, from focus rings to animations, adds up to a better experience for your users.
