I don’t want a header that takes up the entire page initially when loaded on a desktop. Too much scrolling to get to the menu bar (if I have it below the header). If I upload a smaller height image it just magnifies it to the 1920 x 1080 resolution. Am I stuck with these header dimensions or what? In the demo of Pro, which I bought, it has the ideal size where you can still see the menu and some of the content below. How do I replicate this?
