CSS make default direction rtl instead of ltr

Question

Is there any way to make default direction of the whole CSS file RTL instead of LTR? If not, is there any tool that insert 'direction:rtl' in each CSS tag? My CSS file have 20000 lines of code and it's to hard to change all of them.

Answer 1

Not necessarily the best solution, but an option is to use this universal css selector: *

* {
    direction:rtl;
}
