Hi Steven ( @mojo1979 ),
Thank you for reaching out.
The layout of the theme doesn’t allow such changes. It is displaying in two rows for a more convenient experience on devices with smaller resolutions.
However, you can try decreasing the font-size depending on the device resolution.
Try using this CSS code:
@media (max-width: 650px) {
.main-navigation > ul > li > a
{
font-size: 10px;
margin-left: 7px;
}
}
Place this CSS code in the Appearance->Customizer->Additional CSS section.
Best Regards,
Pavle
