Sidebar Width

Sure, you want it smaller or larger?

here is larger:

@media (min-width: 1200px) {
#content .main.col-lg-9 {width: 70%;}
#content aside.col-lg-3 {width: 30%;}
}

Kadence Themes

i add your code
@media (min-width: 1200px) {
#content .main.col-lg-9 {width: 70%;}
#content aside.col-lg-3 {width: 30%;}
}

can i now move elements to right?
