pub fn apply_background_image(
ent: &mut EntityWorldMut<'_>,
tag: &str,
attrs: &Attributes,
)Expand description
Points an element’s background at the image its bg names, or takes a
background image away when bg names a colour or a gradient instead.
The image travels the same road as an <image src>: an
lumen_assets::ImageSource the asset pipeline resolves, decodes and
caches, marked lumen_assets::BackgroundImage so it paints behind
the content and never sizes the element. An <image> keeps its src as
its one source, so a bg image on one is ignored.
attrs is the element’s whole resolved style: with no bg left, an
image the element had is taken away, and with no bg-fit the image
covers the box.
