I would like to add a linear gradient background to the Express theme. I placed the below code in the theme.liquid and I set the background color in theme/settings to transparent to allow the background gradient to appear. It works great and I have a linear gradient background.
However, the collections list creates a sticky banner as you scroll down and the products texts and images bleed through onto the sticky banner. How can I have a linear gradient background without the text/images of the products on the home page appearing through the collections list sticky banner?
