How to center the menu with Hueman theme

Hi I am trying the Hueman theme and the menu bar goes to the left and I have tried with

.nav-menu {
   display: table;
   margin: 0 auto;
}

.main-navigation {
	display: table;
}

.main-navigation {
	text-align: center;
}

to center the menu and does not work.
Even more, it is very close one item of the other and nothing seems to work to separate them…
Thanks in advance
Jaio
