Choose scalable line-height values and compare ratio inheritance with fixed lengths. Separate line boxes from paragraph margins and test larger child text.

Read legacy rect coordinates and compare them with clip-path inset distances. Keep layout sizing and clipping separate when migrating existing CSS.

CSS / Reference / box-sizing: Content and Border Boxes, Including Small-Size Limits
Calculate content-box and border-box sizes, including margins and the minimum content-size limit. Apply resets deliberately and check external components.

Build box shadows from offsets, blur, and spread, then inspect clipping and layering. Distinguish box geometry from glyph or transparent-image shadows.
CSS / Reference / border-style: Border Patterns, Side Order, and Hidden Conflicts
Choose border patterns for each side and inspect shorthand resets. Compare none with hidden in collapsed tables and account for zero computed border widths.
