Bootstrap 4 class for a single flex item to take up the available space


In Bootstrap 4, if you want a flex item to take up the available space, then use the flex-grow-|1 class.

If you want the first flex item to take up the space, then the following is the code −

<div class="d-flex mb-3">
  <div class="p-2 flex-grow-1  bg-warning">One</div>
  <div class="p-2 bg-secondary">Two</div>
  <div class="p-2 bg-danger">Three</div>
</div>

Above you can see, I have used the flex-grow-1 class in the first div class −

<div class="p-2 flex-grow-1  bg-warning">
  One
</div>

The following is an example to implement the flex-grow-0|1 class −
