Naming Pattern
All utilities follow: [property]-[side/variant]-[size]
.margin-top-base
↓ ↓ ↓
property side size
This makes names guessable! If you forget a name, look at nearby utilities to remember the pattern.
Pro Tips
✅ Combine utilities — Use multiple classes together
<div class="padding-base margin-bottom-l text-align-center">
✅ Use semantic values — base, s, l are clearer than arbitrary numbers
.padding-base ← Clear
.padding-16px ← What was 16px again?
✅ Reference the sizes — Use the consistent scale across margin, padding, gap, width, height
.margin-l .padding-l .gap-l .width-l
<!-- All use the same --space-l value -->
❌ Don’t fight utilities — Use them instead of writing custom CSS
<!-- Good -->
<div class="padding-base margin-bottom-l">
<!-- Don't do this -->
<div style="padding: 1rem; margin-bottom: 2rem;">
Common Sizes
| Use Case | Classes |
|---|---|
| Tiny spacing | .margin-xs, .padding-xs, .gap-xs |
| Small spacing | .margin-s, .padding-s, .gap-s |
| Regular spacing | .margin-base, .padding-base, .gap-base |
| Large spacing | .margin-l, .padding-l, .gap-l |
| Extra large | .margin-xl, .padding-xl, .gap-xl |
