title: Add line break to ::after or ::before pseudo-element content
body: <p>I do not have access to the HTML or PHP for a page and can only edit via CSS. I've been doing modifications on a site and adding text via the <code>::after</code> or <code>::before</code> pseudo-elements and have found that escape Unicode should be used for things such as a space before or after the added content.</p>
  <p>How do I add multiple lines in the <code>content</code> property?</p>
  <p>In example the HTML break line element is <em>only to visualize</em> what I would like to achieve:</p>
  <pre class="lang-css prettyprint-override"><code>#headerAgentInfoDetailsPhone::after {
    content: 'Office: XXXXX &lt;br /&gt; Mobile: YYYYY ';
  }
  </code></pre>
