Hello Mohammad,

Have a look at the below CSS, I did a quick google search and found the below CSS attributes for Braille. Not sure if it will address your query.

@media braille is a method to target braille devices.

Hello Mohammad,

Perhaps the following two pieces of information are not directly helpful in which case I apologize.

First, the ARIA Working Group is currently working on adding new attributes for customizing braille output (aria-braillelabel, aria-brailleroledescription). Those properties are only in the ARIA draft so far (cf. [1] below); they will hopefully be added to ARIA 1.3.
I'm actively involved in this effort and would be very interested in more information about your use case. Would you be able to share an example of the kind of content you are creating and what you have tested?

Second, the APA's pronunciation task force (cf. [2] below) is probably also relevant. Its work is at a similarly early stage howevere.

Regards,
Peter Krautzberger.
