Hello there,

I am not sure if it is theme-related issue. Could you please confirm if this issue also to happen even with the default WordPress theme?

well i added this for the header.

.site-header.fixed {
position: fixed !important;
}

and i noticed the header gets bigger too when you try to make pics bigger

Ok i need the header to stay normal size,i want to zoom in on stuff but header gets bigger and i dont want that. can I include a fixed hieght and width for header only in the css above
