Remove outline.

a {
    outline: none;
}

Don’t.

This makes your site inaccessible to keyboard users. That may not sound like a big deal, but many people with relatively minor disabilities are unable to use a mouse.

At the very least, replace it with something else to indicate focus.

:link:focus, :visited:focus { 
-moz-outline: none; 
}
