To prevent long words from overflowing a flex container, you can use the CSS property `word-break` to control how text wraps within the container.

<!-- BEGIN COPY / PASTE -->
    <div class="flex-container" style="display: flex; width: 200px; border: 1px solid #ccc;">
      <p style="word-break: break-word;">

      </p>
    </div>
    <!-- END COPY / PASTE -->

Additional Comment:

The `word-break: break-word;` property ensures that long words will break and wrap onto the next line within the container.
This approach is particularly useful in responsive designs where container widths may vary.
Make sure the container has a defined width to see the effect of the word break.
