Frontpage Content Area being restricted

In Appearance > Customize > Additional CSS, remove this:

.no-sidebar .inside-article > *,
.no-sidebar #comments,
.no-sidebar .nav-links {
	max-width: 700px;
	margin-left: auto;
	margin-right: auto;
}

Then, add this at the very bottom:

body.no-sidebar:not(.home) .inside-article > *,
body.no-sidebar:not(.home)  #comments,
body.no-sidebar:not(.home) .nav-links {
	max-width: 700px;
	margin-left: auto;
	margin-right: auto;
}

You’re welcome!
