Bubble Font Size ​

You can change text size in Definer in two ways:

  • Scale Slider: quick, bubble‑only.
  • Theme Editor: precise, global (applies everywhere in the extension).

Scale Slider ​

  • Open Definer Options → Bubble.
  • Move the Font Scale slider between 50% and 200% (100% is the default).
  • The change applies only to the popup bubble and doesn’t affect the rest of the interface.

Theme Editor ​

Use this when you want to change font size across the entire extension.

  • Open Definer Options → Appearance → Create Theme → Fonts → Size.
  • Adjust the size and click Save.
  • This creates a copy of your current theme with the new font size and applies it throughout Definer (not just the bubble).

Bubble‑only via CSS (Theme Editor) ​

If you only want to change the font size inside the bubble via your theme:

  1. Definer Options → Appearance → Create Theme → CSS
  2. Add: #definer-bubble { --font-size: 20px }
  3. Replace 20px with your preferred size (px, em, rem, or %) and click Save.
