Impeccable Style

Polish the details that separate good UI from great UI.

Core Principle

Great design is invisible. Users notice when it's wrong, not when it's right.

This skill finds and fixes the small details that break the illusion.

When to Use

• Final polish pass before release

• UI feels "off" but can't pinpoint why

• Consistency audit across components

• Elevating MVP to production quality

• Reviewing designs for attention to detail

The Polish Checklist

Spacing & Alignment

/* BAD: Inconsistent spacing */ .card { padding: 12px; } .modal { padding: 15px; } .panel { padding: 10px; }

/* GOOD: Spacing scale */ --space-xs: 4px; --space-sm: 8px; --space-md: 16px; --space-lg: 24px; --space-xl: 32px;

Audit Questions:

• All spacing uses consistent scale (4px, 8px, 16px, etc.)?

• Elements align to invisible grid?

• Margins between sections are consistent?

• Padding inside containers is consistent?

Typography

/* BAD: Random font sizes */ h1 { font-size: 28px; } h2 { font-size: 19px; } p { font-size: 15px; }

/* GOOD: Type scale / --text-xs: 0.75rem; / 12px / --text-sm: 0.875rem; / 14px / --text-base: 1rem; / 16px / --text-lg: 1.125rem; / 18px / --text-xl: 1.25rem; / 20px / --text-2xl: 1.5rem; / 24px */

Audit Questions:

• Font sizes follow a scale?

• Line heights are comfortable (1.4-1.6 for body)?

• Headings have proper hierarchy?

• Text is readable (contrast ratio ≥ 4.5:1)?

Colors

Audit Questions:

• Using defined color palette only?

• Hover states are consistent (darker/lighter by same %)?

• Disabled states are consistent (opacity or gray)?

• Focus states are visible (not just color)?

• Error/success/warning colors are consistent?

Micro-interactions

/* BAD: No transition */ .button:hover { background: blue; }

/* GOOD: Smooth transition */ .button { transition: all 150ms ease-out; } .button:hover { background: blue; transform: translateY(-1px); }

Audit Questions:

• Buttons have hover/active states?

• Transitions are 150-300ms (not jarring)?

• Loading states exist for async actions?

• Focus states work for keyboard navigation?

Icons & Images

Audit Questions:

• Icons are same style (outlined vs filled)?

• Icons are same size in similar contexts?

• Images have proper aspect ratios?

• Placeholder/loading states for images?

• Alt text for accessibility?

Border Radius

/* BAD: Inconsistent */ .button { border-radius: 4px; } .card { border-radius: 8px; } .input { border-radius: 6px; }

/* GOOD: Radius scale */ --radius-sm: 4px; --radius-md: 8px; --radius-lg: 12px; --radius-full: 9999px;

Shadows

/* GOOD: Shadow scale for elevation */ --shadow-sm: 0 1px 2px rgba(0,0,0,0.05); --shadow-md: 0 4px 6px rgba(0,0,0,0.1); --shadow-lg: 0 10px 15px rgba(0,0,0,0.1); --shadow-xl: 0 20px 25px rgba(0,0,0,0.15);

Common Polish Issues

Issue Fix

Buttons different heights Standardize to 32/40/48px

Text touches edges Add padding (min 16px)

Modal too wide Max-width: 500px for forms

Icons misaligned Vertical-align or flexbox

Truncated text text-overflow: ellipsis

Flash of unstyled content Proper loading states

Visual Audit Process

• Squint Test: Blur vision - do elements have clear hierarchy?

• Grid Check: Does everything align to an invisible grid?

• Color Count: Are you using <5 colors consistently?

• Spacing Scan: Is spacing predictable and rhythmic?

• Interactive Check: Do all interactive elements feel responsive?

Before/After Examples

Spacing

Before: [Logo] [Nav] [Button] After: [Logo] [Nav] [Button] (consistent gaps)

Alignment

Before: Text starts at random x positions After: All text aligns to same left edge

Transitions

Before: Instant color change on hover After: 150ms ease-out transition

Polish Priority Order

• Spacing - Most common issue, biggest impact

• Typography - Readable text is non-negotiable

• Colors - Consistency builds trust

• Interactions - Makes UI feel responsive

• Details - Border radius, shadows, icons
