Open Design > Theme and select the Font tab. A grid of 11 options is shown, each with a sample 'Aa Bb Cc 123' preview: Default, Inter, Roboto, Open Sans, Lato, Source Sans, Nunito, Work Sans, DM Sans, IBM Plex Sans, and Figtree. Click one to apply it across the whole form.
Each step has a Text Style tab in the right panel. This is where you control the size and weight of individual text elements — form title, description, question text, helper text, consent text, progress text, and timer text. Sizes and weights can be set independently for Mobile, Tablet, and Desktop breakpoints using the device selector at the top of the tab.
Form Title — the main heading above the form.
Description — the subtitle or supporting text below the title.
Question Text — the question on each step.
Helper Text — the optional clarifying line beneath a question.
Consent Text — the text in the consent block.
Progress Text, Progress Bar, Timer Text — the labels around the progress indicator.
