T-Shirt Sizing Convention

Yumma CSS 3.22 introduces a t-shirt sizing convention for all border-radius utilities. This change replaces numeric suffixes with intuitive labels like xs, sm, md, & lg, making it easier to remember & apply consistent radius values.

Updated Utilities

All utilities that previously used numeric values now use t-shirt sizes. This includes the base br- utility as well as directional variants like btr-, brr-, bbr-, & blr-.

<div class="br-2"></div>
<div class="br-sm"></div>

The new convention follows a standard scale:

<div class="br-2 btr-4"></div>
<div class="btr-md br-sm"></div>

Supported Sizes

You can choose from 7 different sizes:

SizeValue
00
xs0.125rem
sm0.25rem
md0.375rem
lg0.5rem
xl0.75rem
xxl1rem
3xl1.5rem
