• Title for your fault: Issue w/ Dark Mode
• Fault Description: Madara WP Theme has a issue in some pages that even you switching to dark mode, some parts from the page won't change to their own dark theme
• What have you done to try to fix the issue: I was checking some pages which also had madara as wp theme and saw the following code in every page:
