Previous Question Next Question

When using Flexbox, centering items both vertically and horizontally within a container can be achieved by setting the appropriate alignment properties. Ensure your container has the correct CSS properties applied.

<!-- BEGIN COPY / PASTE -->
    <style>
      .flex-container {
        display: flex;
        justify-content: center; /* Centers items horizontally */
        align-items: center;    /* Centers items vertically */
        height: 100vh;          /* Ensures the container has height */
      }
    </style>

    <div class="flex-container">
      <div>Your content here</div>
    </div>
    <!-- END COPY / PASTE -->

Additional Comment:

Ensure the container has a defined height, like "100vh", to allow vertical centering.
"justify-content: center" aligns items horizontally in the center.
"align-items: center" aligns items vertically in the center.
Check for any additional styles that might override these properties.
