Typography
Type controls on a block: font, size, weight, spacing, and colour.
Typography sets the type on a block, the font, size, weight, line height, letter and word spacing, alignment, and colour, along with decoration, transform, and style.
Most of the time you will reach for your global typography rather than setting these by hand, so the type stays consistent across the site. The per-block controls are here for the exceptions, a heading that needs to break the scale just this once.
