XF 2.2 delete borders on sidebar widgets

[Old Nick]

Hello,

I can't find the tips for delete borders on widget, i'm ok for changing background but borders...

[data-widget-key="online_list_online_statistics"] {
    .block-minorHeader {background: @xf-pageBg;}
    .block-body {background: @xf-pageBg;}
    .block-footer {background: @xf-pageBg;}
}

How to ? for header, body and footer ?
Thanks !!
