Why isn't my CSS grid layout displaying correctly in Firefox but works fine in Chrome?

Answer

When your CSS grid layout works in Chrome but not in Firefox, it might be due to differences in how the browsers interpret certain CSS properties or a missing prefix. Here's a basic example to ensure cross-browser compatibility.

<!-- BEGIN COPY / PASTE -->
    <style>
      .grid-container {
        display: grid;
        grid-template-columns: repeat(3, 1fr);
        grid-gap: 10px;
      }
      .grid-item {
        background-color: lightblue;
        padding: 20px;
        text-align: center;
      }
    </style>

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

Additional Comment:

Ensure you are using the latest version of Firefox, as older versions may have incomplete grid support.
Check for any CSS properties that might require vendor prefixes, although modern browsers generally handle grid without them.
Validate your CSS for any syntax errors that could be ignored by one browser but not another.
Use browser developer tools to inspect and debug the grid layout in Firefox.
