I have a problem with block environment in Beamer. I am using persian/arabic language. For the block environment, I want the title of the block and the text inside the block be aligned on the right hand side but they are aligned on the left hand side. I saw the guidance of Salim Bou in the following link for the itemize and enumeration environment that were so useful but for the block environment I am totally confused . The best way to write arabic in beamer
