 Abstract: This module extends the CSS sizing properties with keywords that represent content-based "intrinsic" sizes and context-based "extrinsic" sizes, allowing CSS to more easily describe boxes that fit their content or fit into a particular layout context. This is a delta spec over CSS Sizing Level 3.
 Ignored Terms: block-level box
