UNKNOWN image§
=for image :class<inline> :src<asset_files/images/action-bar.png> :width<30\%>It is expected to be displayed below the content and expand horizontally to fill the area.
It allows placing children at the start or the end. In addition, it contains an internal centered box which is centered with respect to the full width of the box, even if the children at either side take up different amounts of space.
The action bar as a buildable§
The Gnome::Gtk4::ActionBar implementation of the Gnome::Gtk4::R-Buildable interface supports adding children at the start or end sides by specifying start or end as the type attribute of a <child> element, or setting the center widget by specifying center value.

A Gnome::Gtk4::ActionBar's CSS node is called actionbar. It contains a revealer subnode, which contains a box subnode, which contains two box subnodes at the start and end of the action bar, with start and end style classes respectively, as well as a center node that represents the center child.
Each of the boxes contains children packed for that side.
