type or paste code here
```<div class="row">
  <div class="col-xs-4">
  <button class="btn btn-block btn-primary">Like</button>
  </div>
  <div class="col-xs-4">
  <button class="btn btn-block btn-info">Info</button>
  </div>
  <div class="col-xs-4">
  <button class="btn btn-block btn-danger">Delete</button></div>
  </div>
