    London. Michaelmas term lately over, and the Lord Chancellor sitting in
    Lincoln's Inn Hall. 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 class="content-box">
  This is a bunch of text split into three columns using the CSS
  <code>columns</code> property. This includes a <code>column-count</code> value
  of <code>3</code>, a <code>column-width</code> value of <code>auto</code>, and
  a <code>column-height</code> value of <code>5em</code>. The
  <code>column-wrap</code> value is set to its initial value, <code>auto</code>;
  when a <code>column-height</code> value is included,
  <code>column-wrap: auto</code> resolves to <code>wrap</code>, which allows the
  columns to wrap onto multiple rows. The text is equally distributed over the
  columns, and placed into multiple rows.
