You could try some absolute positioning, but this is something that’s a bit of a challenge to get completely right.
.sf-menu li {
position: relative;
}
.sf-menu li a i {
position: absolute;
}
.sf-menu li.menu-home a i {
top: 35%;
left: 40%;
}
You may have to adjust the percentages individually for each menu item, and if that’s the case, you can use .sf-menu li.menu-about-us a i {}
, .sf-menu li.latest-news a i {}
, etc.
