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;
}
