Define class names for header levels

[alvarolozano]

Is your feature request related to a problem? Please describe.
When using TailwindCSS or other CSS frameworks, header tags (h1, h2, h3) do not have default styles. When I try to define the styles by using the classNames prop, with { header: 'text-xl '}, it applies the same class for all the header levels, so they look the same

Describe the solution you'd like
When defining "header" styles, allow to pass an object with class name definitions for each level

header: {
   h1: 'text-3xl',
   h2: 'text-2xl',
   h3: 'text-xl'
}
