What does the 'Edited' tag mean in the style guide form?
The 'Edited' tag shows that the value of the field has been edited.
You can use style guides to create theme-specific overrides to Site Studio styles and templates. Theme-specific overrides can use theme inheritance. For example, you can set-up a theme and sub-theme to both use the style guide manager. In this example, the values set in the parent theme are inherited by the sub-theme.
Changes made to values in the sub-theme will show the 'Edited' tag to show you that they have been changed from the values inherited from the parent theme.
For more detailed information, see Style guide manager in the user guide.
