Yumma CSS 3.16
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.
| Legacy | Latest | Prefix |
|---|---|---|
border-top-radius | border-block-start-radius | bbsr- |
border-bottom-radius | border-block-end-radius | bber- |
border-left-radius | border-inline-start-radius | bisr- |
border-right-radius | border-inline-end-radius | bier- |
Corners also adopt logical naming:
| Legacy | Latest | Prefix |
|---|---|---|
border-top-left-radius | border-start-start-radius | bssr- |
border-top-right-radius | border-start-end-radius | bser- |
border-bottom-left-radius | border-end-start-radius | besr- |
border-bottom-right-radius | border-end-end-radius | beer- |
Border Width
Directional border width utilities now use logical properties for better layout flexibility.
| Legacy | Latest | Prefix |
|---|---|---|
border-top-width | border-block-start-width | bbsw- |
border-bottom-width | border-block-end-width | bbew- |
border-left-width | border-inline-start-width | bisw- |
border-right-width | border-inline-end-width | biew- |
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>Upgrade
