Editing the Style Guide Template
Navigate to Templates > Morning Star | Style Guide > click "Edit with Elementor."
The Style Guide page has been set up with various sections that show examples of all the typography, and button styles, column gaps, and section padding.
These styles are controlled by the Style Kids plugin. Style Kits is a plugin by AnalogWP that allows you to globally control your theme styles. The Style Kits library includes Templates, Style Kits, and Blocks. For more details please see the style kit support page.
