Using a header tag with an h1, the h1 is showing with all the font modifications. The background image will not show. I have verified the image location is valid by using the same code for an img tag. The header will also not push down the lower elements when the screen reduced. Below is the html and css:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
