一种方法是使用display: table-cell;和vertical-align: middle;- 你也可以使用,line-height因为它<span>有一个固定的高度.

nav ul li a:hover span {
    font: 30px"Dosis", sans-serif;
    text-transform: uppercase;
    position: relative;
    left: 120px;
    width: inherit;
    height: inherit;
    display: table-cell;
    vertical-align: middle;
    text-align: left;
}
