Text formatting

Basic text formatting is assembled by Classic formatting adapters and the default Block preset. Each product owns its controls and installation paths. This page demonstrates Core commands; see editor compatibility.

Marks express text formatting. StarterKit already includes the bold, italic and underline capabilities shown here (MIT). For independent assembly, use the public exports of @quirekit/extension-bold, @quirekit/extension-italic and @quirekit/extension-underline, alongside document, paragraph, text and view dependencies.

Commands

editor.chain().focus().toggleBold().run()
editor.chain().focus().toggleItalic().run()
editor.chain().focus().toggleUnderline().run()
const active = editor.isActive('bold')

Controls read editor state instead of maintaining a second formatting model. At an empty selection, marks affect subsequent input; with selected text, they apply to that range.

Live effect

Select a few words, then use the formatting buttons. Continue typing, undo, or download JSON to inspect marks.

This demonstrates generic formatting in a DOM view, not the full Word font-property space.
