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:

| Size | Value | | ----- | -------- | | 0 | 0 | | xs | 0.125rem | | sm | 0.25rem | | md | 0.375rem | | lg | 0.5rem | | xl | 0.75rem | | xxl | 1rem | | 3xl | 1.5rem |
