Navigation

I would recommend creating a child theme and then you want to edit the
.main-navigation a {
color: #000000;
display: block;
font-size: 10px;
font-weight: normal;
margin-left: 1em;
padding: 0.4em;
text-decoration: none;
text-transform: uppercase;
}
This is line 573 in style.css

Glad I could help.

not a problem. nice clean theme.
