Create a larger hit area for links with a nicely sized background color hover state that doesn't throw off the inline layout of your text.

links.css

a {
    padding: 2px 2px 0;
    margin: -2px -2px 0;
    -webkit-border-radius: 3px;
    -moz-border-radius: 3px;
    -ms-border-radius: 3px;
    -o-border-radius: 3px;
    border-radius: 3px;
    color: #3A57AB;
}
a:hover {
    background-color: #3A57AB;
    color: #EEE;
}
