How to remove Bar header on top of page?

[BCRC]

Hello!
I’m not sure if I’m missing something or what, but I’m working on this page: http://landoffersco.com/blog/.

At the top there is a grey bar that says blog. It’s not a section that I recall creating. What is the best way to go about deleting it?
This is what it is:

<header class="x-header-landmark x-container max width"> <h1 class="h-landmark entry-title"><span>Blog</span></h1> </header>

Hi There,

Thank you for writing in, please add this to Theme Options > CSS

/*hide the header landmark*/
.x-header-landmark {
	display: none;
}

Hope it helps,
Cheers!
