Sidebar width change

Hi, need help with changing sidebars width in FinanceMag Theme.

I changed these lines in wide.css and tablet.css, but nothing on the site is changed.

.sidebar.right { position:relative; float:right; overflow:hidden; padding-bottom:20px; height:100%; width:160px; }
.sidebar.left { position:relative; float:right; overflow:hidden; padding-bottom:20px; height:100%; width:310px; }

I know that I need to change images main-lr.png, top-lr.png, bottom-lr.png too.

Can you give me advice, how to make it work.

Hi!
To change the sidebar width you have to edit the code

.sidebar{
	width:281px !important;
}

in the file style.css.
