Background image to scroll with content

I am trying to get my background image to scroll along with the content on the page. As of right now the content scrolls but the background stays fixed…

It is a custom html form and I’ve placed the following code into the “custom html” “Edit” CSS field. I can’t figure out why its not working.

body {
background-color: #000000;
background-size: 100%;
background-image: scroll;
background-image: url("_/theme/stonebackground.png");
background-repeat: vertical;
}

If you’re talking about this edit button:

image

then what you type into it should be HTML. If you want to add CSS to it, you’d need to surround it with style tags.

Yes the tags are there as well. But the background still does not scroll…

Then you’re getting into the CSS itself, which other folks here are far more equipped to answer than me. But, in general, I’m not sure that the custom HTML for a custom HTML form is the right place to style the body attribute. You may want to create a styled div that contains a drop point for components inside it.
