Hi,
Thank you for contacting us. Please accept my apologies for the delay in response. I really appreciate your patience.
You can use the below CSS code to control the logo size when scrolling.
.is-sticky .site-header .custom-logo-link img.custom-logo {
max-width: 200px;
}
Set your own maximum width to meet your requiement.
To apply that code to your website, add it to Additional CSS under dashboard (/wp-admin) > Appearance > Customize menu.
For the size when not scrolling, use this code:
.site-header .custom-logo-link img.custom-logo {
max-width: 200px;
}
I hope this reply helps.
Regards,
Kharis
