Theme Footer Widget Doesn't Work in Columns Layout

Hi! I’m working on a website of my client which is built on Sahifa WordPress Theme. I’m facing a issue with its footer widget as it doesn’t work in Horizontal Columns Layout. I want 3 columns layout for footer widget but it doesn’t float them all 3 columns are align up and down vertically instead of align horizontal beside each other. I’m done with CSS it doesn’t work anymore. Seems its a problem with the theme or with any built-in function.

You don’t have any account in envato market. from where you got the theme files?
You have to contact the theme author using original theme purchaser account to get any technical support. Thanks
