Hi there,

go to Customizer > Widgets --> Right Sidebar and delete the widget.

Yes, I deleted the widget. But the blue color is still there.

how to delete the background blue color or change it to white.

Thanks

Go to Customizer > Additional CSS and DELETE this:

/* Featured widget */
.sidebar .widget:first-child,
.sidebar .widget:first-child .widget-title{
	background-color: #83b0de;
	color: #fff;
}
.sidebar .widget:first-child a,
.sidebar .widget:first-child a:hover {
	color: #fff;
}
