How children overflowing their container should affect layout

In CSS the primary effect of this property is to control whether contents of a parent container that overflow that container should be displayed anyway, be clipped, or trigger the container to become a scroll container. However it also has secondary effects on layout, the main ones being:

  • The automatic minimum size Flexbox/CSS Grid items with non-Visible overflow is 0 rather than being content based
  • Overflow::Scroll nodes have space in the layout reserved for a scrollbar (width controlled by the scrollbar_width property)

In Taffy, we only implement the layout related secondary effects as we are not concerned with drawing/painting. The amount of space reserved for a scrollbar is controlled by the scrollbar_width property. If this is 0 then Scroll behaves identically to Hidden.

Variants§

§

Visible

The automatic minimum size of this node as a flexbox/grid item should be based on the size of its content. Content that overflows this node should contribute to the scroll region of its parent.

§

Clip

The automatic minimum size of this node as a flexbox/grid item should be based on the size of its content. Content that overflows this node should not contribute to the scroll region of its parent.

§

Hidden

The automatic minimum size of this node as a flexbox/grid item should be 0. Content that overflows this node should not contribute to the scroll region of its parent.

§

Scroll

The automatic minimum size of this node as a flexbox/grid item should be 0. Additionally, space should be reserved for a scrollbar. The amount of space reserved is controlled by the scrollbar_width property. Content that overflows this node should not contribute to the scroll region of its parent.
