Advanced: building templates
The pages above cover everything you need to use templates. This part is for users who want to go further — build a new template from scratch or change an existing design. It involves some HTML/CSS/JS, so start here only if you're comfortable with basic web code; otherwise stick to Fill in a template.
Building and editing templates — create a template, edit its code, rename parameters, duplicate.
Template examples (real) — full, working template code and schemas.
