Change sidebar width

Regarding:

https://wordpress.org/support/topic/change-sidebar-width-4?replies=4

With:

#main .widget-area {
	width: 20%;
}

– instead of about 33.6% – I reduced the width of the sidebar.

With:

.secondary #content {
	margin: 0 32.5% 0 9.464285714286%;
}

– instead of 51.25% – I enlarged the main part.

And with:

#main .widget-area .widget {
	margin: 0 0 0 12%; /* This creates the column between the vertical rule and the widgets */
}

– instead of 24.2% – I reduced the empty space between both.
