How to remove the menu animation?

Working on https://i4mediation.com/ (temp passw StellaB), the menu changes in height on scroll. How do I turn the animation off?

Hello, try to replace this code in your additional CSS (row 67):

max-width: 140px;

…with this:

max-width: 140px !important;

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
