Hi, 
I have two questions I hope you can help me with. 
First, I'm trying to build my portfolio, but I can't seem to remove the subheader on portfolio items. Normally there is a option that says 'Subheader | Hide', but I can't find it on the portfolio-item-page. If there is a CSS-option to remove the subheader everywhere, that's also ok!
Second, where can I change the hight of the background image showing on my page? I want to change it on all my pages. 
Hope you can help!

1. Under Theme options > Header & Subheader > Subheader section you got an option to remove subheader globally.
2. You can change header's height with css which is under Theme options > Custom CSS & JS > Custom CSS:
body:not(.template-slider) #Header {Just increase 200px value.min-height: 200px;
}
