How to visually format custom styles in Sanity's block content/richtext editor field.

9 replies
Last updated: May 20, 2020
I'm adding a custom style to a block content/richtext editor field and was trying to find out how I can format the text in the editor to reflect the different style visually in order for editors to "get it". There's no mention of that in the docs over at so I was wondering - is it actually possible?

For reference, I added an object to the styles array:
styles: [
        { title: 'Lead', value: 'lead' },
..and I'd like to make that font just a tad larger. If there's no visual change, it makes it harder for editors to understand what's going on and kinda kills the WYSIWYG experience.

Same question here. Did you figure out a way to do this?

I want to have a “heading” style, and perhaps make it bold or slightly larger in the rich text editor in Sanity studio (without using h1-6 tag specifically)

{ name: ‘body’,
title: ‘Body’,
type: ‘array’,
of: [
type: ‘block’,
styles: [
{ title: ‘Normal’, value: ‘normal’ },
{ title: ‘Heading’, value: ‘heading’ }
marks: {
decorators: [
{ title: ‘Strong’, value: ‘strong’ },
{ title: ‘Emphasis’, value: ‘em’ }
