How to add subscript & superscript text to your Story
Formatting text in subscript and superscript using the text format bar
In Prezly's story editor, you can use the option in the formatting context menu. All you have to do is select the text which you want to format as subscript or superscript and click on the "S" button in the menu that pops up.
If you click it once, your text will be formatted as superscript.
If you click it again, it will be formatted as subscript. Easy :)
