How do site designs (layouts) work?
Choose a design in the Style section of step 1 (Template). You can switch designs at any time - your texts, images and sections stay untouched, and the color scheme applies on top of any design.
How do I export or import my site configuration?
In the Publish step use Export/Import JSON. The file contains title, description, theme (color_scheme, logo, cover, custom_css), sections and template. Import applies the configuration to the current draft - save it afterwards.
What can developers customize on a seller site?
Custom CSS (Branding step, 60000-character limit) can use the variables --ss-accent, --ss-bg, --ss-surface and --ss-text, and each design scopes its styles under the .ss-layout- root class (e.g. .ss-layout-modern). Use Export/Import JSON (Publish step) to back up or migrate the theme and sections between sites, and the Embed section for raw HTML widgets (up to 20000 characters, height 100–1200 px).
