Because Skeletons only work when your project contains the same variables and global structure.
The Style Guide includes all global tokens:
When you paste a Skeleton section into a project that has the Style Guide installed, Webflow automatically maps:
Example:
If Skeleton uses --section-padding-medium or --text-size-h2, those instantly adapt to your customized variables.
This is what makes Skeletons feel magically “on brand” right after pasting.
Without the Style Guide, nothing will map correctly.
