How to make notification box float in the center

Using Bulma css framework, I try to make the notification box popup at about the center of the page, without interrupting existing data (it is a notification that pops for 3 seconds and then it should disappear). For example: 2 images on top of each other(snippet 1), and I want the notification box to float on top of them without pushing any content(snippet 2)

  <div class="level main">
    <div class="level-item">
      <figure class="image is-128x128">

Solution 1:

Simply give the notification position: absolute along with a z-index which is higher than the element you want it to sit on top of (1 will likely work fine):

.notification.is-primary {
  position: absolute;
  z-index: 1;
}
