WooCommerce Store Custom Background Image

Hi,

I was wondering what do I need to do to be able to change the background image of my store. I went to the store page and changed the background image there, but it didn’t show up. I found this post before:

I went to Highend Options > General Settings > Custom CSS and posted all the codes, but still didn’t work. I’m not really a website developer, just a small business owner. Thanks in advance for any help!
