Introducing logical border properties, a standalone translate utility, & expanded border width control.

Logical Border Properties

Yumma CSS 3.16 transitions from physical to logical border properties. This change improves support for different writing modes & ensures layouts remain consistent across various languages.

Border Radius

We've refactored directional border radius utilities to use logical equivalents. Physical directions like top & left are now represented by block & inline start/end.

Corners also adopt logical naming:

Border Width

Directional border width utilities now use logical properties for better layout flexibility.

New Utilities

This release adds 3 new core utilities to expand your design capabilities:

Translate Utility

A standalone translate utility is now available, following our shift towards standalone transform properties.

<div class="t-t-4 ...">
Translated by 1 rem!
</div>

Logical Widths

We've implemented group utilities for block & inline border widths:

  • Border Block Width (byw-): Sets both top & bottom border widths.
  • Border Inline Width (bxw-): Sets both left & right border widths.
<div class="byw-2 bxw-1 ...">
Custom border axis control.
</div>
