[Theme: Make] how do I get a front page like the theme demo?

I am basically trying to create a front page like the demo picture of this theme. i.e a full width picture under the header followed by the three column foother.

I can’t find any options in the theme customization link/menu to achieve this.

I am a newbie to WordPress and websites etc so don’t know anything about coding. Is the above achievable without coding?

Thanks
