How to make textarea lines auto direction line by line?

Question

I'm having a problem with making textarea lines right-to-left for Persian and Arabic and left-to-right for English or others.

I can make the whole textarea auto direction but what about split lines of the text in textarea?

Answer 1

You could add atribute dir to your textarea element with value auto:

<textarea dir="auto"></textarea>

Now, browser will automaticaly detect text direction for each line.
