<div>
  <h1>This is an <strong>example</strong> block of <strong>text</strong>.</h1>
  <p>An SVG is used to <strong>emphasize</strong> a single word of a block of text by giving it an underline that uses an SVG. Semantically it is emphasized with a <code>strong</code> tag and visually it is emphasized with the SVG.</p>
</div>

  &::after {
    content: '';

    right: -0.5rem;
    height: 0.75rem;

    // Position the line behind the text so that
    // it is still easily readable
    z-index: -1;

    // The SVG is added as an SVG background image
    background-image: url('https://s3-us-west-2.amazonaws.com/s.cdpn.io/664131/underline.svg');
    background-repeat: no-repeat;

    // This allows the SVG to flex in size to fit
    // any length of word. If the word is short,
    // the SVG will be stretched vertically, if it
    // is long, the SVG will be stretched horizontally.
    // The jagged nature of this particular SVG works
    // with this transforming.
