How can I center a div both vertically and horizontally using flexbox?

Asked on Oct 22, 2025

Answer

To center a div both vertically and horizontally using Flexbox, you can utilize the properties `justify-content` and `align-items`. These properties allow you to align items within a container efficiently.
<!-- BEGIN COPY / PASTE -->
    <style>
      .container {
        display: flex;
        justify-content: center; /* Centers horizontally */
        align-items: center;    /* Centers vertically */
        height: 100vh;          /* Full viewport height for vertical centering */
      }
      .centered-div {
        width: 200px;
        height: 100px;
        background-color: lightblue;
      }
    </style>

    <div class="container">
      <div class="centered-div">
        Centered Content
      </div>
    </div>
    <!-- END COPY / PASTE -->
Additional Comment:
  • The `display: flex;` property on the container enables Flexbox layout.
  • `justify-content: center;` aligns the child horizontally in the center.
  • `align-items: center;` aligns the child vertically in the center.
  • Setting `height: 100vh;` on the container ensures it takes the full viewport height, which is useful for vertical centering.
