  <h2>Notes</h2>
  <ul>
    <li>By applying width and height of 1em to our SVG icon (using HTML attributes) it is predictably sized by default.</li>
    <li>1em = the font-size of its parent element, the a.call-to-action.</li>
    <li>Due to its em-based dimensions, a "link icon" pattern of this type is flexible – it will scale with its parent anchor’s font-size.</li>
    <li>If need be it can also have its size further tweaked in a relative/flexible way via an em-based <code>font-size</code>, and thus will still scale up and down based on the font-size of its parent.</li>
    <li>This technique requires the “viewbox” attribute being present on the svg</li>
    <li>We apply the width and height =1em as inline attributes on the SVG rather than using CSS only because the inline approach avoids potentially massive icons in cases where CSS doesn’t load.</li>
    <li>To get the colour matching, apply fill="currentColor" as an inline attribute on the svg’s path.</li>
    <li>Now, when you apply a hover colour to the anchor in CSS, the icon will just pick that up.</li>
    <li>Applying inline-flex to the anchor makes the vertical-alignment of text and icon easier.</li>
    <li>Add aria-hidden on the icon because it’s mainly decorative so we don’t want it read out by screen readers.</li>
