fun Modifier.background(color: CSSColorValue?, vararg backgrounds: Background.Repeatable): Modifier(source)
Configure an element's background appearance.
Background layers are specified in bottom-to-top order. Note that this is the opposite of how CSS does it, which for this property expects a top-to-bottom order. However, we decided to deviate from the standard here for the following reasons:
Everything else in HTML uses a bottom-to-top order (e.g. declaring elements on a page).
This method accepts a color parameter first (in front of the vararg background layers), which renders on the bottom of everything else. This sets the expectation that "bottom" values come first.
