Table of options#
From the design point of view, each component has a number of options. These options and their names are platform agnostic, and each implementation should adapt these to fit into their framework.

Line height#
Key examples showing the line height for headings. The first example in English has a 1.3x multiplier for its line height. The second example in Simplified Chinese uses a 1.5x multiplier. Both examples read “Mirror icons that represent movement,” with first example in English and the second example in Simplified Chinese.

Margins#
Top margins are the heading font size divided by 1.125. Bottom margins are 0.25× the heading font size.
