@@ -62,9 +62,9 @@ We've added some `UnoCSS` utilities styles to help you with that:
 - If you need to change border radius for an entire left or right side, use `border-inline-start/end`. `UnoCSS` shortcuts are `rounded-is` for left side, `rounded-ie` for right side. Example: `rounded-l-5` should be replaced with `rounded-ie-5`.
 - If you need to change border radius for one corner, use `border-start-end-radius` and similar rules. `UnoCSS` shortcuts are `rounded` + top/bottom as either `-bs` (top) or `-be` (bottom) + left/right as either `-is` (left) or `-ie` (right). Example: `rounded-tl-0` should be replaced with `rounded-bs-is-0`.
