To create a smooth fade-in effect for a background image on page load using CSS, you can use CSS animations to gradually change the opacity of an element. Here's a simple example to demonstrate this effect.

<!-- BEGIN COPY / PASTE -->
    <style>
      .fade-in-bg {
        background-image: url('your-image.jpg');
        background-size: cover;
        background-position: center;
        height: 100vh;
        opacity: 0;
        animation: fadeIn 2s forwards;
      }

      @keyframes fadeIn {
        to {
          opacity: 1;
        }
      }
    </style>

    <div class="fade-in-bg"></div>
    <!-- END COPY / PASTE -->

Additional Comment:

Ensure the image URL in the background-image property is correct.
The animation duration (2s) can be adjusted to make the fade-in slower or faster.
The forwards value in the animation property keeps the final state of the animation.
This example assumes the background image covers the entire viewport height (100vh).
