a{
text-align: center;
display: table;
height: 100%;
width: 100%;
background: rgba(0,0,0,0.4);
}
a span{
display: table-cell;
vertical-align: middle;
}
No problemos! we call the "old" table solution to the rescue.
Setting display of parent as a table and then the child as table-cell did the trick.
Enjoy!

center align
