In Kadence, the visual/text editor is the ideal tool for adding copyright information to the theme footer. You can modify the text, add dynamic fields like the current year, and use HTML to include links or additional information. It also offers built-in options to populate various placeholders. Here are the available placeholders that can be utilized:
The copyright can be aligned, fonts can be changed, link colors and styles can be changed, margins can be changed, and more.
To change the copyright in your theme, go to Appearance > Customizer > Footer and find the copyright widget in the General Tab. Click to open, then make your changes and Publish.
NOTE: If some of these options are unavailable, you most likely do not have the Kadence Pro installed.
