How to remove grey line from footer in prestige theme?

Hi, I want to remove the grey line that can be found in the footer as shown. How do I go about doing this?

@PM999 You need to add this code in the theme files. For which you need to go to Online Store > Actions (Active theme) > Edit Code > Assets, under assets add the code at the bottom of theme.css file.

.Footer{border-top:0px !important;}

That worked - thank you!
