What it does
Design engineering principles for making interfaces feel polished. Use when building UI components, reviewing frontend code, implementing animations, hover states, shadows, borders, typography, micro-interactions, enter/exit animations, or any visual detail work. Triggers on UI polish, design details, "make it feel better", "feels off", stagger animations, border radius, optical alignment, font smoothing, tabular numbers, image outlines, box shadows.
Details that make interfaces feel better
Great interfaces rarely come from a single thing. It's usually a collection of small details that compound into a great experience. Apply these principles when building or reviewing UI code.
Quick Reference
| Category | When to Use |
|---|---|
| Typography | Text wrapping, font smoothing, tabular numbers |
| Surfaces | Border radius, optical alignment, shadows, image outlines, hit areas |
| Animations | Interruptible animations, enter/exit transitions, icon animations, scale on press |
| Performance | Transition specificity, will-change usage |
Core Principles
1. Concentric Border Radius
Outer radius = inner radius + padding. Mismatched radii on nested elements is the most common thing that makes interfaces feel off.
2. Optical Over Geometric Alignment
When geometric centering looks off, align optically. Buttons with icons, play triangles, and asymmetric icons all need manual adjustment.
3. Shadows Over Borders
Layer multiple transparent box-shadow values for natural depth. Shadows adapt to any background; solid borders don't.
4. Interruptible Animations
Use CSS transitions for interactive state changes, they can be interrupted mid-animation. Reserve keyframes for staged sequences that run once.
5. Split and Stagger Enter Animations
Don't animate a single container. Break content into semantic chunks and stagger each with ~100ms delay.
6. Subtle Exit Animations
Use a small fixed translateY instead of full height. Exits should be softer than enters.
