title: How do you add a shadow underneath a header that is gray and blurry in CSS?
body: <p>I wanted to find out how to make a shadow underneath my header that is both gray and blurry. I have read a <a href="https://www.w3schools.com/css/css3_shadows_box.asp" rel="nofollow noreferrer">W3 Schools article</a> about this but I want it to only be below my header and horizontal while making it blurry and gray.</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>#header {
    /*In This Line- CSS for Box Shadow*/
    position:fixed
    }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;header id="header"&gt;
  My Header
  &lt;!-- Shadow --&gt;
  &lt;/header&gt;</code></pre>
  </div>
  </div>
  </p>
