This is not RTL support but support for ways to explicitly set styles based on the direction.

Better than using rtl:ml-4 is to use ms-4 which stands for margin-inline-start: .... Prefer logical properties over physical ones. But that is not possible in all cases. There, rtl: and ltr: prefix come handy.

Moving to Tailwindcss make it hard to implement bidirectional text support unless we define new rules to use logical styles.

Thanks for your reply. Though Fediverse is independent from instances ,but it doesn’t give good feeling when one sees instances like this go down.

I understand but I hope there be some way to save the instance. What about FSFE which is sponsor of the instance?

Wish more information be released on why it is happening. If @[email protected] needs some help for moderation, I am sure there are volunteers including me. If it is financial issue, there is no harm for requesting support.
