title: How to style a span content tag using inline styles
body: <p>I want to create a span with inline styles for an email:</p>
  
  <pre><code>&lt;span style="display: inline-block; width: 16;"&gt;&lt;/span&gt;
  </code></pre>
  
  <p>In my helper I have tried this:</p>
  
  <pre><code>content_tag(:span, style: "display: inline-block; width: 16;")
  </code></pre>
  
  <p>The words "display: inline-block; width: 16;" are displayed on the screen.</p>
