Hey Tim,
the height of the contracted logo on mouse scroll is determined by the “max-height” declaration for the “.small-logo” CSS class (the theme’s main “style.css”, line 258); you can set its value to any required height. The same class has declarations that govern the transition of the logo from its normal size to the contracted size – you can change them or delete them altogether to control how the logo switches its states.
Sincerely,
Andrii / Satori Studio
