Full width footer widget

Shapely theme by default has 4 footer widgets. I need just 1 full screen footer widget for my website.

Hello there,

I hope you are doing well today.

Could you please provide a link to your website so that I can inspect it?
You need to go to Appearance > Widgets and remove the other footer widget then add new CSS to make it full width.

Best Regards,

Currently I have just social icons in 1st footer widget, others are empty.
I tried going to Appearance > Widgets but there is no option to remove footers.
