Bootstrap 4 .flex-fill class

Use the flex-fill class to set the flex items to be equal width in Bootstrap 4.

Set the flex item inside the <div> set as flex −

<div class="d-flex mb-3 bg-primary">
  <div class="p-2 flex-fill bg-danger">Example 1</div>
  <div class="p-2 flex-fill bg-warning">Example 2</div>
  <div class="p-2 flex-fill bg-info">Example 3</div>
  <div class="p-2 flex-fill bg-danger">Example 4</div>
</div>
