Why isn't my flexbox container centering items vertically in this layout?

Asked on Nov 08, 2025

Answer

Flexbox is a powerful tool for aligning items both horizontally and vertically. If your flexbox container isn't centering items vertically, it's likely due to a missing or incorrect CSS property. Ensure you are using "align-items: center" on the flex container.

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

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

Additional Comment:

Ensure the flex container has a defined height to see vertical centering, such as using "height: 100vh" for full viewport height.
Check if any child elements have margins or padding that might affect alignment.
Verify that "display: flex" is applied to the correct parent container.
