Header can't be changed

I’m using Sydney version 1.45

I want to change the header size, but can’t reduce the header size from default 300.

any idea?


Hello there,

Have you set lower value in Appearance > Customize > Header area > Header Media > Header height [default: 300px]; and clear any applied cache? Site caching often prevents recent changes to take effect. https://codex.wordpress.org/I_Make_Changes_and_Nothing_Happens

I clear the cache and no any diffrent , i also checled on mobile and don’t
see any change .

Try adding the below CSS code to Appearance > Customize > Additional CSS.

    .header-image {
      height: 200px !important;
