### Sizing and spacing
By default, Figma specifies sizing and spacing in px. When Bootstrap uses a different unit, the px value should be converted to an equivalent value. To aid these conversions, most of the values used in Figma are a fraction or multiple of 16px. For example, a 56px H1 in Figma translates to 3.5 rem in Bootstrap's Sass.
