These default features are set whenever taffy is added without default-features = false somewhere in the dependency tree.

block_layout default

calc default

Enables calc() values for all layout algorithms

content_size default

Causes all algorithms to compute and output a content size for each node

Affects layout::LayoutOutput.content_size, layout::Layout.content_size…

detailed_layout_info default

Causes algorithms to stores detailed information of the nodes in TaffyTree, with only CSS Grid supporting this.
