Widget SideBar

Hi,

You can install this plugin : https://ww.wp.xz.cn/plugins/widget-options/ if you want to use multiple background color otherwise use what @cryptex_vinci answered. Then options will be added on each widget and you can add custom classes for example ‘widget-bg-dark’ then on your style.css or custom css options you can use :

.widget.widget-bg-dark{ background #333; }

I hope this helps. Thanks!

Cheers,
