title: I added "background-image" via CSS in Wordpress twenty-seventeen: doesn't display
body: <p>I want to override Wordpress's Twenty-Seventeen header image by adding my own background-image via CSS. However, it just displays blank white... Here's the body's html:</p>
  <pre><code>&lt;body class=&quot;page-template-default page page-id-5 logged-in wp-custom-logo has-header-image page-one-column title-tagline-hidden colors-light page-soins&quot; data-aos-easing=&quot;ease&quot; data-aos-duration=&quot;400&quot; data-aos-delay=&quot;0&quot; cz-shortcut-listen=&quot;true&quot;&gt;
  </code></pre>
  <p>and here's my CSS to disable wordpress's header image:</p>
  <pre><code>.page-soins .wp-custom-header {
       display: none;
  }
  </code></pre>
  <p>and here's my CSS to add my background image instead:</p>
  <pre><code>body.page-soins {
      background: url(&quot;images/backgrounds/soins-bg-1.jpg&quot;) no-repeat center center fixed;
      background-size: cover;
  }
  </code></pre>
  <p>Finally, here's the link to the page: <code>http://latelierdegaia.ch/soins</code></p>
  <p>Can anyone help?</p>
