Hi, i use DesignNow Template. But i want change the desing(the graphics, style) of the columns right and left?For e.g.: Change my columns ( images.cjb.net/fe23b.jpg ) to maybe other columns ( images.cjb.net/caa50.jpg ).

Hi,

that menu has class menu , and it can be accessed from css using:

.column_right ul.menu {
...

Current css rules are in template_css.css and template_css.php + one of style1.php - style4.php if you are uing one of four predefined styles.
