How can I move my shortcode countdown clock to the center of the Top Nav Menu?

Done, whats the code to change the font? And whats the default Generatepress font that my theme is using, i cant find it.

You're currently using the System Stack fonts, which are the local browser fonts, these are:

font-family: -apple-system, system-ui, BlinkMacSystemFont, "Segoe UI", Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol";
