Answer

To ensure color contrast passes in dark mode using Bootstrap, you can utilize Bootstrap's CSS variables to define and adjust colors dynamically. This approach allows you to maintain accessibility by ensuring sufficient contrast between text and background colors.

<!-- BEGIN COPY / PASTE -->
        <div class="bg-dark text-light p-3">
            <h1 class="display-4">Dark Mode Example</h1>
            <p class="lead">This text uses Bootstrap's dark mode variables for contrast.</p>
        </div>
        <!-- END COPY / PASTE -->

Additional Comment:

Use Bootstrap's predefined classes like `bg-dark` and `text-light` to ensure high contrast.
You can customize these variables in your SCSS if needed to meet specific contrast requirements.
Always test your color combinations using a contrast checker tool to ensure they meet WCAG standards.
