Remove sidebar completely

Hi there,
How do i remove the sidebar completely, so the website website if “full screen”?

Hello there,

Try adding this CSS code to Appearance > Customize > Additional CSS from dashboard.

    .site-content #secondary.widget-area {
      display: none;
    }
    .site-content #primary.content-area {
      width: 100% !important;
      padding-left: 0 !important;
    }
