I would like to style text as superscript in React Native. How would this be accomplished? Is there a way to make use of the Javascript sup() string method to return a string as superscript within a <Text> object?

I got this working for me using a view container and flex.

<View style={{flexDirection: 'row', alignItems: 'flex-start'}}>
    <Text style={{fontSize: 20, lineHeight: 30}}>10</Text>
    <Text style={{fontSize: 11, lineHeight: 18}}>am</Text>
</View>

Here is the link to this in action https://repl.it/Haap/0

Cheers!

Comments
  • I tried your solution but it gives me problems as described in the comments of one of the answers here stackoverflow.com/questions/49536698/…
  • I needed to fix because a special aspect ratio needs between the lineHeights
  • textAlignVertical is android only!
  • Getting an error when I include this inside an existing View: "Views nested within a <Text> must have a width and height"
  • Also, from the React Native documentation, embedding a View within Text will work in iOS only. Not cross-platform.
  • That's right but if you are on android you could simply use textAlignVertical: 'top'
  • I think for now (if you want to use Text + nested exponents) you have to do really ugly mixtures of Views and Text Elements. Maybe take a look at productpains there is a voting system for future features. I added the link to CSS vertical align property page with a reference to the sub/super properties.
  • On Android, I tried the textAlignVertical: 'top' property like so: <Text>Productname<Text style={{fontSize: 9, textAlignVertical: 'top'}}>®</Text></Text> to no avail. Any thoughts?
