How do I use This?

Hover the columns to expand them and reveal content. It uses flexbox to grow shrink as needed and position the text.

HTML
<div class="row expand-column-wrapper">
  <div class="column">
    <p class="expand-column-content">Hello there.</p>
  </div>
  <div class="column">
    <p class="expand-column-content">If you hover</p>
  </div>
  <div class="column">
    <p class="expand-column-content">over each section</p>
  </div>
  <div class="column">
    <p class="expand-column-content">a couple of words</p>
  </div>
  <div class="column">
    <p class="expand-column-content">will appear</p>
  </div>
</div>
