Change header height only in mobile view

Hi,

Is there a simple way to change the header height only on mobile devices?
I have tried this but unfortunately do not work:

@media (max-width: 480px) {
.ish-row_inner {
height: 60px;
}
}

I like to have it the same height as the sticky menu with the hamburger icon floating in the middle.

Thanks in advance.
Greets!
