Reply To: Remove a menu showing only on mobile version

If you want the Social Icons to appear when viewed on desktop you can add overflow: hidden; to the .site-header .widget around line 1838 in your css –

.site-header .widget {
	color: #fff;
	margin: 0 0 20px;
	overflow: hidden;
}

If you don’t want them to appear on mobile devices, then add this to your responsive section (480px) –

.simple-social-icons {
	display: none;
}
