Answer

To implement a CSS grid layout with fallbacks, you can use a combination of Flexbox and Grid. Flexbox can serve as a fallback for older browsers that do not support CSS Grid. Here's a basic example to illustrate this approach.

<!-- BEGIN COPY / PASTE -->
    <style>
      .container {
        display: flex; /* Fallback for older browsers */
        flex-wrap: wrap;
      }

      .container > div {
        flex: 1 1 100%; /* Flexbox fallback layout */
      }

      @supports (display: grid) {
        .container {
          display: grid; /* Modern browsers */
          grid-template-columns: repeat(3, 1fr);
          gap: 10px;
        }
      }
    </style>

    <div class="container">
      <div>Item 1</div>
      <div>Item 2</div>
      <div>Item 3</div>
    </div>
    <!-- END COPY / PASTE -->

Additional Comment:

Use Flexbox as a fallback by setting "display: flex" and configuring flex properties for children.
Use the "@supports" rule to check for Grid support and apply Grid styles if available.
The "flex: 1 1 100%" ensures each item takes full width in Flexbox, simulating a single-column layout.
Grid properties like "grid-template-columns" and "gap" are applied only if Grid is supported.
