How do I make Wix recognize screen resolution so my strip goes full screen?

Hi, Im trying to create a ‘welcome strip’ at the top of my home page. I want this strip to be responsive in a way that it recognizes the users screen resolution and displays this strip full screen. Not just in width but also in height. At the moment Im only able to get it to stretch to full screen in width but the height is fixed. How can I make this responsive so it adapts to different screen resolutions?
