FontSize extension

VersionDownloads

This extension enables you to set the font size in the editor. It uses the TextStyle mark, which renders a <span> tag. The font size is applied as inline style, for example <span style="font-size: 14px">.

Install 

npm install @tiptap/extension-text-style

This extension requires the TextStyle mark.

import { Editor } from '@tiptap/core'
import { TextStyle, FontSize } from '@tiptap/extension-text-style'

new Editor({
  extensions: [TextStyle, FontSize],
})

This extension is installed by default with the TextStyleKit extension, so you don’t need to install it separately.

import { Editor } from '@tiptap/core'
import { TextStyleKit } from '@tiptap/extension-text-style'

new Editor({
  extensions: [TextStyleKit],
})
