White space to left of Home Page: Want to Remove it

Hi there,

it looks like you installed the Navigator Site which adds a fixed side header.
To remove that go to Customizer > Additional CSS and delete:

/* ------
Fixed Header
------- */

@media (min-width: 769px) {
	body {
		margin-left: 200px;
	}

	.site-header {
		position: fixed;
		left: 0;
		top: 0;
		width: 200px;
		z-index: 300;
		height: 100%;
		overflow: auto;
		overflow-x: hidden;
		-webkit-backface-visibility: hidden;
		-webkit-overflow-scrolling: touch;
		transition: .1s ease;
	}
	
	.admin-bar .site-header {
		top: 32px;
	}
	
	.site-header .main-navigation li {
		float: none;
	}
}

.inside-header {
	display: -webkit-box;
	display: -ms-flexbox;
	display: flex;
  -webkit-box-flex: 1;
      -ms-flex: 1;
          flex: 1;
  -webkit-box-orient: vertical;
  -webkit-box-direction: normal;
      -ms-flex-direction: column;
          flex-direction: column;
  -webkit-box-align: center;
      -ms-flex-align: center;
          align-items: center;
	height: 100%;
	-webkit-box-sizing: border-box;
	        box-sizing: border-box;
}

.site-branding,
.site-logo {
	-webkit-box-ordinal-group: 2;
	    -ms-flex-order: 1;
	        order: 1;
}

.header-widget {
	-webkit-box-ordinal-group: 4;
	    -ms-flex-order: 3;
	        order: 3;
	margin-top: auto;
	margin-bottom: 20px;
}

.nav-float-right .inside-header .main-navigation {
	-webkit-box-ordinal-group: 3;
	    -ms-flex-order: 2;
	        order: 2;
	float: none;
	margin-top: 20px;
	margin-bottom: 50px;
}

.nav-float-right .header-widget {
	float: none;
	top: auto;
	max-width: 100%;
}

.dropdown-hover .site-header .main-navigation .main-nav .sub-menu {
	opacity: 1 !important;
	display: block !important;
	right: auto !important;
	position: relative;
	top: auto;
	float: none;
	text-align: center;
}

Then i suggest you go to Customizer > Layout > Header and enable Navigation as Header.

Thank you David, that worked and it looks amazing now!

Glad to hear that
