Hey there mikeshotit,
This can be done by adding some custom CSS. The easiest way to do that, if your theme doesn’t already have custom CSS tab, would be to add it in your site using the following plugin
https://www.ads-software.com/plugins/simple-custom-css
Once the plugin is installed and activated you can add this code to Appearance >> Custom CSS:
.site-logo {
max-width: 200px;
}
.main-navigation ul {
margin-top: 8px;
}
First part will increase the logo size, I’ve added the second one to move menu slightly down so it is centered vertically in the header.
Hope this helps.
Best regards,
Bojan
