Struct VisualStyle 

pub struct VisualStyle {
    pub bg: Color,
    pub border_color: Color,
    pub border_w: f32,
    pub radius: [f32; 4],
    pub opacity: f32,
    pub shadow: Shadow,
    pub pixel_snap: bool,
}

The paint half of a NodeSpec: background, border, corner radii, opacity, shadow and pixel snapping.

Fields

bg: Color

border_color: Color

border_w: f32

radius: [f32; 4]

Corner radii (logical px), clockwise from the top-left: [tl, tr, br, bl]. NodeSpec::radius sets all four; the per-corner builders (radius_tl, …) override one — later calls win, like CSS border-radius followed by border-top-left-radius.

opacity: f32

Group opacity, 0..=1 and 1 by default: multiplied into the alpha of every quad this node and its subtree emit, and into every descendant’s own opacity. This is the cheap group opacity — a per-quad alpha multiply, not an offscreen composite — so a subtree whose own pieces overlap shows its seams through the fade where a compositing implementation would not. Nothing else changes: an invisible subtree still lays out, still takes clicks and is still read by assistive technology, exactly like CSS opacity: 0.

shadow: Shadow

The drop shadow cast behind this node (see Shadow).

pixel_snap: bool

Paint the background, border, shadow and fragment with each edge on a whole physical pixel (pixelSnap). Off by default: a box is drawn where layout put it, so a gap between two boxes is there at any scale. On, its edges land where a text’s backgrounds’ do and where every other snapped box’s do, so snapped boxes that share an edge in layout, and a snapped box beside a text’s background, meet without a seam. Layout, hit-testing and the children are untouched.
