Hi coachgee2,
You can add CSS to your site via Appearance > Customize > Additional CSS.
Paste the following code there and adjust the font-size number to your liking:
.menu-item {
font-size: 12px;
}
That will change your menu item font so that it will be smaller and fit more items.
Is there a quick/easy and non techie way of decreasing the space between the logo and the main menu items?
The following CSS will make the menu area a bit wider on large screens like laptops/desktops:
@media screen and (min-width: 1230px) {
.main-navigation {
width: 800px;
float: left;
}
}
If that moves your menu below your site title, you can decrease the 800px. (The default is 700px.)
