Oh I seeā€¦

You can modify your link as button using the following css code:

#mainnav li {
    padding: 0;
    margin-left: 3px;
}

#mainnav li a {
    padding: 0 10px;
}

#mainnav ul li a:hover {
    background-color: green;
    border-radius: 5px;
    color: white;
}

and you can use simple custom css plugin to put the code in above
