Need help removing the color strip from bottom of site (Grant fluid template)

Hi – I'm almost finished creating a site using the Grant template, but have some colored bands showing up at the bottom of the desktop and mobile views that I can't figure out how to remove via custom CSS.

Here's a link to my WIP site, password "regatta" (no quotes).

I've attached screenshots of the bar as well. 

Thank you!

Use this CSS code

div.header-burger {
    display: none !important
}
