Feature: support for subscript and superscript

See original GitHub issue

Hi! I have to add a button for subscript in the editor toolbar. But turns out, the subscript and superscript functionalities aren’t fully implemented. I did see a few variables (IS_SUBSCRIPT, IS_SUPERSCRIPT) in the source code, but I didn’t see them being used anywhere. I also went through the doc, but wasn’t able to find anything of much relevance. So I just wanted to know the state of this feature. Also, please let me know if I am missing something. Thanks 😃

It is available as part of TextFormatType

Like strikethrough implementation you have to implement for ‘subscript’ or ‘superscript’

You have to add class name here PlaygroundEditorTheme.js
Provide CSS style here PlaygroundEditorTheme.css
editor.dispatchCommand(FORMAT_TEXT_COMMAND, 'superscript')

thanks @Proful. Any clue why are we using CSS to implement this rather than using <sup> and <sub> tags?

Maybe we should be? We can look into it. I guess the classes might be more flexible than relying on browser styling, but now I’m thinking about the semantics of not having the tags.
