Answer

Previous Question

Creating a CSS-only dark mode toggle involves using the `:checked` pseudo-class on a hidden checkbox input to switch between light and dark themes. This method is simple and doesn't require JavaScript.

<!-- BEGIN COPY / PASTE -->
    <input type="checkbox" id="dark-mode-toggle" style="display: none;">
    <label for="dark-mode-toggle">Toggle Dark Mode</label>

    <style>
      body {
        background-color: white;
        color: black;
        transition: background-color 0.3s, color 0.3s;
      }

      #dark-mode-toggle:checked ~ body {
        background-color: black;
        color: white;
      }
    </style>
    <!-- END COPY / PASTE -->

Additional Comment:

This example uses a hidden checkbox to toggle the dark mode.
The `label` element is used to trigger the checkbox when clicked.
The `:checked` pseudo-class is used to apply dark mode styles when the checkbox is checked.
CSS transitions are used for smooth color changes.
