How to change global font size for all retool apps

Hello, It is my first time using retool and I cannot find a way to change global font size for all retool apps.

Go to your settings and under Advanced, you can add CSS...

Ok, thank you, but is there any specific piece of code that changes all items that have text in them?
I can only find ways to change specific things, like buttons.

._retool-button1 button span {
  font-size: 24px;
  margin: 10px
:root {
  --font-size-24: 1.5rem;
  --font-size-20: 1.25rem;
  --font-size-18: 1.125rem;
  --font-size-17: 1.0625rem;
  --font-size-16: 1rem;
  --font-size-14: 0.875rem;
  --font-size-12: 0.75rem;
  --font-size-11: 11px;
  --font-size-10: 0.625rem;
  --line-height-solid: 1;
  --line-height-32: 2rem;
  --line-height-28: 1.75rem;
  --line-height-24: 1.5rem;
  --line-height-20: 1.25rem;
  --line-height-18: 1.125rem;
  --line-height-16: 1rem;
  --line-height-14: 0.875rem;
  --line-height-12: 0.75rem;

This covers a lot of stuff, but it seems like there are still specific pieces of UI that don't use variables to set the font size.
