Answer 1

use position css property and set top,right,bottom and left to Zero.. set z-index if needed in my case in i used text-indent because i dont want to show link "text" but if you want to show link "text" , just don't use text-indent

display:block;
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
text-indent: -99999px;
