Reduce header image

How can I reduce the slider image height? I’ve tried changing the value in Appearance > Header > Header area > Header Media > Header Height and it does not change? I would like it to be about half the height it currently is now.

Hello there,

To control it, try adding this CSS code to Appearance > Customize > Additional CSS from dashboard.

.header-image {
   height: 150px !important; 
}
