Headings
Customize headings to your liking and will. Out of the box, there are three types of heading levels supported, namely heading_1, heading_2 and heading_3.
The element receives text and key as parameter and should return node type value.
ℹ️
Node Type Value is anything that can be rendered: numbers, strings, elements or an array.
