Hi @jiraiya84
I already answered you via support ticket from the AttesaWP website, but I also answer you here in case it could be useful to someone else 🙂
This small change can be made with custom CSS.
Go to your WordPress Dashbard under “Appearance-> Customize-> Additional CSS” and paste this code:
.nav-top {
max-height: none;
}
.nav-top .container {
font-size: 16px;
padding: 1.2em 1em;
}
Change the font-size to control the font size inside the top bar.
And change the first part of padding (1.2em) to change the height of the top bar.
