Craft

Version 1.1

Craft is the standard guideline for building with Webstudio.

It contains a set of standards, CSS variables, and Tokens that make building websites fast, maintainable, and reusable. It also enables sharing Projects without mixing different naming conventions.

Open Props, an open source CSS variables library that helps accelerate adaptive and consistent design, is part of Craft.

The Content Block component designates regions on the page where pre-styled instances can be inserted in Content mode.

In Content mode, you can edit any direct child instances that were pre-added to the Content Block, as well as add new instances predefined in Templates.
To predefine instances for insertion in Content mode, switch to Design mode and add them to the Templates container.

It works pretty well.
