Default text settings

How can I change the default settings of the text in the body of my post boxes from centred to justified or left?

I'd be grateful for the code and if you could tell me where to put the code.

Go to your forum's CSS in the administration panel of your forum, press CTRL + F on your keyboard, and search for '.postbody .content {' in the CSS. When you find that in the CSS, paste this code in that area:

Code:

   text-align: justified;

If that doesn't work, then just change 'justified' to 'left'.

Thanks!
