Enable the app embed
Start by toggling on the Flexi Typography app embed in your theme editor. This gives you access to global font sizing controls.
Adjust heading sizes
Each heading (H1–H6) has its own desktop and mobile sliders, so you can fine-tune sizes separately for larger and smaller screens.
Customize paragraph sizes
Paragraph text comes with three adjustable styles, which are small, default, and large. Use the input slider to adjust their sizes.
