Align centre on post archive page

Hi there,

can i see the archive on your site ?

https://rovinrv.com/rv-living/

1. remove the empty sidebar from the archives in Customizer > Layout > Sidebar
2. If need, limit t the width of the archive content container with some CSS:

body:not(.single) .container {
    max-width: 800px;
}

Many thanks

You’re welcome
