change font size on button click

I need help, does anyone know how I can place a button that can increase or decrease the font size of a text … ?? thank you

It’s not straightforward. If you want to increase/decrease the font size of everything in the app then that might be too complex, but if it’s just one or two text components then you can format it using a HTML template and a user-specific number column.

<p style="font-size:30px">This is a paragraph.</p>

The “30” part is replaced by your user-specific number column. On every click of a button, increase or decrease it.
