Using pages (templates)
Pages (templates) are a collection of sections ↗ that are configured to give your online store a consistent look and feel.
In the theme editor, you can discover which templates are applied to which pages, and then edit them to customize the information displayed to your customers.
Editing a template applies the changes to every page that uses that page template. For example, if you add a newsletter signup form to a collection template, then all collections pages that use the default collection template now display the newsletter signup form.
You can have up to 1000 templates in total.
