In order to set the background color or image on your WordPress site, you must employ a container layout or box layout. Otherwise, any background image or color you set won’t be visible.
- In order to do that, navigate to General Settings >> Site Style. Under the Container Layout section, select Boxed Layout.
- Now, navigate back to General Settings >> Background.
- Click on Select Image to upload and set your background image for your site.
- Otherwise, select any color by clicking on the circular color palette icon next to Background Color to set the background color for your site.
