Values

block-level
The element generates a block-level box, and participates in a block formatting context. Other formatting contexts, such as flex formatting contexts, may also work with block-level elements.
inline-level
The element generates an inline-level box, and participates in an inline formatting context.
run-in
The element generates a run-in box. Run-in elements act like inlines or blocks, depending on the surrounding elements.
contents
The element lays out its contents using flex layout.
none
The element generates no boxes, and does not participate in any formatting context.
table-row-group, table-header-group, table-footer-group, table-row, table-cell, table-column-group, table-column, table-caption
The element is an internal table element, and participates in a table layout context.

table-cell and table-caption are layout-specific leaf types; the rest are layout-specific internal types.
ruby-base, ruby-text, ruby-base-container, ruby-text-container
The element is an internal ruby element, and participates in a ruby layout context.

ruby-base and ruby-text are layout-specific leaf types; ruby-base-container and ruby-text-container are layout-specific internal types.
layout-specific internal types
These display types require their parent and children to be of particular display types. For example, a table-row box requires its parent to be a table row group box and its children to be table-cell boxes.
layout-specific leaf types
These display types require their parent to be of a particular display type, but can accept any display-inside value. For example, a table-caption box must have a table parent, but can establish any kind of formatting context for its children.
