 - Do not use `rtl-` classes, such as `rtl-left-0`.
 - For icons that should be rotated for RTL, add `class="rtl-flip"`. This can only be used for icons outside of elements with `dir="auto"`.
 - For absolute positioned elements, don't use `left/right`: for example `left-0`. Use `inset-inline-start/end` instead. `UnoCSS` shortcuts are `inset-is` for `inset-inline-start` and `inset-ie` for `inset-inline-end`. Example: `left-0` should be replaced with `inset-is-0`.
-- If you need to change the 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 the 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-is-5`.
 - If you need to change the 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`.
