column-span CSS property

The column-span CSS property makes it possible for an element to span across all columns when its value is set to all.

An element that spans more than one column is called a spanning element.

Try it

column-span: none;
column-span: all;
<section id="default-example">
  <div class="multicol-element">
    <p>
      London. Michaelmas term lately over, and the Lord Chancellor sitting in
      Lincoln's Inn Hall.
    </p>
    <div id="example-element">Spanner?</div>
    <p>
      Implacable November weather. As much mud in the streets as if the waters
      had but newly retired from the face of the earth, and it would not be
      wonderful to meet a Megalosaurus, forty feet long or so, waddling like an
      elephantine lizard up Holborn Hill.
    </p>
  </div>
</section>
.multicol-element {
  width: 100%;
  text-align: left;
  column-count: 3;
}

.multicol-element p {
  margin: 0;
}

#example-element {
  background-color: rebeccapurple;
  padding: 10px;
  color: white;
}
