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, hit areas |
| Animations | Interruptible animations, enter/exit transitions, icon animations |
| 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.
7. Contextual Icon Animations
Animate icons with opacity, scale, and blur instead of toggling visibility. Use exactly these values: scale from 0.25 to 1, opacity from 0 to 1, blur from 4px to 0px. If the project has motion or framer-motion in package.json, use transition: { type: "spring", duration: 0.3, bounce: 0 } — bounce must always be 0. If no motion library is installed, keep both icons in the DOM (one absolute-positioned) and cross-fade with CSS transitions using cubic-bezier(0.2, 0, 0, 1) — this gives both enter and exit animations without any dependency.
8. Font Smoothing
Apply -webkit-font-smoothing: antialiased to the root layout on macOS for crisper text.
9. Tabular Numbers
Use font-variant-numeric: tabular-nums for any dynamically updating numbers to prevent layout shift.
10. Text Wrapping
Use text-wrap: balance on headings. Use text-wrap: pretty for body text to avoid orphans.
11. Skip Animation on Page Load
Use initial={false} on AnimatePresence to prevent enter animations on first render. Verify it doesn't break intentional entrance animations.
12. Never Use transition: all
Always specify exact properties: transition-property: scale, opacity. Tailwind's transition-transform covers transform, translate, scale, rotate.
13. Use will-change Sparingly
Only for transform, opacity, filter — properties the GPU can composite. Never use will-change: all. Only add when you notice first-frame stutter.
14. Minimum Hit Area
Interactive elements need at least 40×40px hit area. Extend with a pseudo-element if the visible element is smaller. Never let hit areas of two elements overlap.
15. No Layout Shift
Content must never reflow after it appears. Reserve space up front for anything that loads or changes: fix dimensions on images and media (width/height or aspect-ratio), give async content a placeholder or skeleton of the same size, and keep dynamic numbers on tabular-nums. Toggling state (loading, error, expanded) must not resize the surrounding layout, and late-loading fonts must not shift text. Animate only compositor properties (transform, opacity), never geometry like width, height, top, or margin.
16. Canonical Tailwind Classes
Prefer a scale class over an arbitrary value when one exists: size-8.5 over size-[34px], duration-220 over duration-[220ms]. Every px on the spacing scale maps by N / 4. Reserve [...] for values with no canonical form (breakpoints, color-mix, cubic-bezier, rounded-[…]).
Common Mistakes
| Mistake | Fix |
|---|---|
| Same border radius on parent and child | Calculate outerRadius = innerRadius + padding |
| Icons look off-center | Adjust optically with padding or fix SVG directly |
| Hard borders between sections | Use layered box-shadow with transparency |
| Jarring enter/exit animations | Split, stagger, and keep exits subtle |
| Numbers cause layout shift | Apply tabular-nums |
| Heavy text on macOS | Apply antialiased to root |
| Animation plays on page load | Add initial={false} to AnimatePresence |
transition: all on elements | Specify exact properties |
| First-frame animation stutter | Add will-change: transform (sparingly) |
| Tiny hit areas on small controls | Extend with pseudo-element to 40×40px |
| Content reflows after load or on toggle | Reserve space up front (fixed dimensions, aspect-ratio, skeleton) |
| Arbitrary value where a scale class fits | Use the canonical class (size-8.5, not size-[34px]) |
Verifying the rendered result
Verify by measuring, not by eyeballing. For any spacing or alignment claim, measure the rendered DOM (getBoundingClientRect between an element and its container's edges) and report the numbers. A screenshot that looks aligned is not evidence.
For complex visual changes, or whenever seeing the rendered result matters, drive the running page through Chrome's built-in DevTools Protocol (CDP) to inspect the DOM, computed styles, and layout, and to capture screenshots. It works against any URL, whatever app or domain is serving it. The tools/cdp.ts helper does exactly this:
npx tsx tools/cdp.ts --out ./temp/shots --shot 'label|<url>'
Pass an optional --measure snippet to read geometry off the rendered DOM. Put any query params the page supports (a forced theme, a route, a flag) straight in the URL. Reach for it when a change is hard to verify from the source alone: layout, spacing, alignment, overflow, theme tokens, or anything that only shows up once rendered. Skip it for simple, self-evident edits (for example, adding a shadow) where the result is obvious from the diff.
Review Output Format
Always present changes as a markdown table with Before and After columns. Include every change you made — not just a subset. Never list findings as separate "Before:" / "After:" lines outside of a table. Group changes by principle using a heading above each table, and keep each row focused on a single diff so the reader can scan the whole list quickly.
Example
Concentric border radius
| Before | After |
|---|---|
rounded-xl on card + rounded-xl on inner button (p-2) | rounded-2xl on card (12 + 8), rounded-lg on inner button |
border-radius: 16px on both nested surfaces | Outer 24px, inner 16px with 8px padding |
Tabular numbers
| Before | After |
|---|---|
<span>{count}</span> on animated counter | <span className="tabular-nums">{count}</span> |
| Default numerals on timer | Added font-variant-numeric: tabular-nums to root |
Rows should cite the specific file and the specific property that changed when it isn't obvious from the snippet. If a principle was reviewed but nothing needed to change, omit that table entirely — empty tables add noise.
Review Checklist
- Nested rounded elements use concentric border radius
- Icons are optically centered, not just geometrically
- Shadows used instead of borders where appropriate
- Enter animations are split and staggered
- Exit animations are subtle
- Dynamic numbers use tabular-nums
- Font smoothing is applied
- Headings use text-wrap: balance
- AnimatePresence uses
initial={false}for default-state elements - No
transition: all— only specific properties -
will-changeonly on transform/opacity/filter, neverall - Interactive elements have at least 40×40px hit area
- No layout shift: space is reserved for loading/async/media content, toggles don't resize the layout

# 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](typography.md) | Text wrapping, font smoothing, tabular numbers |
| [Surfaces](surfaces.md) | Border radius, optical alignment, shadows, hit areas |
| [Animations](animations.md) | Interruptible animations, enter/exit transitions, icon animations |
| [Performance](performance.md) | 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.
### 7. Contextual Icon Animations
Animate icons with `opacity`, `scale`, and `blur` instead of toggling visibility. Use exactly these values: scale from `0.25` to `1`, opacity from `0` to `1`, blur from `4px` to `0px`. If the project has `motion` or `framer-motion` in `package.json`, use `transition: { type: "spring", duration: 0.3, bounce: 0 }` — bounce must always be `0`. If no motion library is installed, keep both icons in the DOM (one absolute-positioned) and cross-fade with CSS transitions using `cubic-bezier(0.2, 0, 0, 1)` — this gives both enter and exit animations without any dependency.
### 8. Font Smoothing
Apply `-webkit-font-smoothing: antialiased` to the root layout on macOS for crisper text.
### 9. Tabular Numbers
Use `font-variant-numeric: tabular-nums` for any dynamically updating numbers to prevent layout shift.
### 10. Text Wrapping
Use `text-wrap: balance` on headings. Use `text-wrap: pretty` for body text to avoid orphans.
### 11. Skip Animation on Page Load
Use `initial={false}` on `AnimatePresence` to prevent enter animations on first render. Verify it doesn't break intentional entrance animations.
### 12. Never Use `transition: all`
Always specify exact properties: `transition-property: scale, opacity`. Tailwind's `transition-transform` covers `transform, translate, scale, rotate`.
### 13. Use `will-change` Sparingly
Only for `transform`, `opacity`, `filter` — properties the GPU can composite. Never use `will-change: all`. Only add when you notice first-frame stutter.
### 14. Minimum Hit Area
Interactive elements need at least 40×40px hit area. Extend with a pseudo-element if the visible element is smaller. Never let hit areas of two elements overlap.
### 15. No Layout Shift
Content must never reflow after it appears. Reserve space up front for anything that loads or changes: fix dimensions on images and media (`width`/`height` or `aspect-ratio`), give async content a placeholder or skeleton of the same size, and keep dynamic numbers on `tabular-nums`. Toggling state (loading, error, expanded) must not resize the surrounding layout, and late-loading fonts must not shift text. Animate only compositor properties (`transform`, `opacity`), never geometry like `width`, `height`, `top`, or `margin`.
### 16. Canonical Tailwind Classes
Prefer a scale class over an arbitrary value when one exists: `size-8.5` over `size-[34px]`, `duration-220` over `duration-[220ms]`. Every `px` on the spacing scale maps by `N / 4`. Reserve `[...]` for values with no canonical form (breakpoints, `color-mix`, `cubic-bezier`, `rounded-[…]`).
## Common Mistakes
| Mistake | Fix |
| ---------------------------------------- | ------------------------------------------------------------------- |
| Same border radius on parent and child | Calculate `outerRadius = innerRadius + padding` |
| Icons look off-center | Adjust optically with padding or fix SVG directly |
| Hard borders between sections | Use layered `box-shadow` with transparency |
| Jarring enter/exit animations | Split, stagger, and keep exits subtle |
| Numbers cause layout shift | Apply `tabular-nums` |
| Heavy text on macOS | Apply `antialiased` to root |
| Animation plays on page load | Add `initial={false}` to `AnimatePresence` |

| Content reflows after load or on toggle | Reserve space up front (fixed dimensions, `aspect-ratio`, skeleton) |
| Arbitrary value where a scale class fits | Use the canonical class (`size-8.5`, not `size-[34px]`) |
## Verifying the rendered result
Verify by measuring, not by eyeballing. For any spacing or alignment claim, measure the rendered DOM (`getBoundingClientRect` between an element and its container's edges) and report the numbers. A screenshot that looks aligned is not evidence.
For complex visual changes, or whenever seeing the rendered result matters, drive the running page through Chrome's built-in DevTools Protocol (CDP) to inspect the DOM, computed styles, and layout, and to capture screenshots. It works against any URL, whatever app or domain is serving it. The `tools/cdp.ts` helper does exactly this:
```sh
npx tsx tools/cdp.ts --out ./temp/shots --shot 'label|<url>'
```
Pass an optional `--measure` snippet to read geometry off the rendered DOM. Put any query params the page supports (a forced theme, a route, a flag) straight in the URL. Reach for it when a change is hard to verify from the source alone: layout, spacing, alignment, overflow, theme tokens, or anything that only shows up once rendered. Skip it for simple, self-evident edits (for example, adding a shadow) where the result is obvious from the diff.
## Review Output Format
Always present changes as a markdown table with **Before** and **After** columns. Include every change you made — not just a subset. Never list findings as separate "Before:" / "After:" lines outside of a table. Group changes by principle using a heading above each table, and keep each row focused on a single diff so the reader can scan the whole list quickly.
### Example
#### Concentric border radius
| Before | After |
| ----------------------------------------------------------- | -------------------------------------------------------------- |
| `rounded-xl` on card + `rounded-xl` on inner button (`p-2`) | `rounded-2xl` on card (`12 + 8`), `rounded-lg` on inner button |
| `border-radius: 16px` on both nested surfaces | Outer `24px`, inner `16px` with `8px` padding |
#### Tabular numbers
| Before | After |
| ------------------------------------------ | -------------------------------------------------- |
| `<span>{count}</span>` on animated counter | `<span className="tabular-nums">{count}</span>` |
| Default numerals on timer | Added `font-variant-numeric: tabular-nums` to root |
Rows should cite the specific file and the specific property that changed when it isn't obvious from the snippet. If a principle was reviewed but nothing needed to change, omit that table entirely — empty tables add noise.
