Thks.

or

I use the following code:

var stylesheet = document.styleSheets[document.styleSheets.length-1];
stylesheet.addRule(".aw-column-"+i, "text-align: right");

Sorry, I was answering the wrong question here :-(

Yes, your code is correct. You may also add grid id selector if you are using multiple grids -

stylesheet.addRule("#myGrid .aw-column-" + i, "text-align: right");
