Column count not working in Ionic/ Angular

Question

In my application I am in need to stack dynamic content div's vertically in column count 3. column count 3 breaks the div content when there are only 4 div's. Could some one help me with this. Attached screenshot for reference

<style>
  .cardHolder {
    background-color: #fff;
    border: 1px solid #ccc;
    padding: 10px;

    width: 100%;
    height: 100px;
    box-sizing: border-box;
    background-color: #90cdc0;
    margin-bottom: 2em;
  }
  .title {
    font-weight: bold;
  }
  .wrapper {
    -moz-column-count: 3;
    -webkit-column-count: 3;
    column-count: 3;
    margin: auto;
    padding: 0;
  }
  ion-content {
    background-color: #ddd;
  }
</style>

<ion-content padding>
  <div class="wrapper">
