How can I use @supports to apply different styles if a browser doesn't support CSS grid?

Answer

The `@supports` rule in CSS allows you to apply styles conditionally based on whether a browser supports a particular CSS feature. This is useful for providing fallback styles when a feature like CSS Grid is not supported.

<!-- BEGIN COPY / PASTE -->
    .container {
      display: flex; /* Fallback for browsers that don't support Grid */
    }

    @supports (display: grid) {
      .container {
        display: grid; /* Use Grid if supported */
        grid-template-columns: repeat(3, 1fr);
      }
    }
    <!-- END COPY / PASTE -->

Additional Comment:

The `@supports` rule checks if the browser supports a specific CSS property and value.
Place the fallback styles outside the `@supports` block to ensure they apply when the feature isn't supported.
Inside the `@supports` block, you can safely use the feature-specific styles.
This approach helps maintain a consistent design across different browsers.
