Change menu direction "Massively"

[ashrafakader]

Hello,
I want to change direction of navigation bar to be "right to left", so I edited the CSS of the theme "main.css" as follows:

Code: Select all

		#navPanel .links {
			direction: rtl;
			float: right;
			list-style: none;
			padding-left: 0;
		}

and

Code: Select all

	#navPanelToggle {
		direction: rtl;
		float: right;

However, no change occurs.
How can I do this?
