CardFilled_Stylesheet.yaml

A filled card: a container on a higher surface, with no shadow or border.

The look of CardFilled (in Cards). How component stylesheets work.

The stylesheet

# CardFilled: the look of each part of the component, by the part's id.
# A value in {{ }} is one of the component's parameters.
styles:
  - id: root
    style:
      width: "{{ width }}"
      height: "{{ height }}"
      background: surface_container_highest
      corner_radius: medium

How it is tied to the component

CardFilled_Component.yaml holds the structure: the parts, each with an id. This file holds the look: each rule's id names a part, and its style is what that part looks like. When a view uses component: CardFilled, Tesserae fills in the parameters (a value like "{{ width }}" becomes the width the view passed), picks a branch of any if:, and puts each rule under the style the part already has, so a part's own style: always wins.

The parts

root (Rect)

Field	Value	What it does
width	the width parameter	Pixels, auto (its content's size, or stretched), or a percentage of the parent such as 50%.
height	the height parameter	Pixels, auto (its content's size, or stretched), or a percentage of the parent such as 50%.
background	surface_container_highest	Its fill: a theme role such as surface, #RRGGBB, any CSS colour, or a gradient such as linear-gradient(90deg, primary, tertiary).
corner_radius	medium	Pixels, or a shape token (none to extra_large, or full for a pill or circle). Per corner: a list [top_left, top_right, bottom_right, bottom_left], or a mapping of corners and edges (top, right, bottom, left) with the rest square.

What it makes

With width: 120, height: 40, each part's style is:

root: {width: 120, height: 40, background: surface_container_highest, corner_radius: medium}

Changing it

Put a CardFilled_Stylesheet.yaml next to your views. Its rules go over this file's, field by field:

styles:
  - id: root
    style: {background: tertiary}
