title: How to use CSS combination of mix-blend-mode and isolation?
body: <p>I have a parent element with a red background. I want an h2 element to blend just some words with the background, and other words, inside a span tag, no.</p>
  
  <p>My example below is not working.<br>
  How to make it work?</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>.bg-red {
    background: red;
  }
  
  .blend {
    mix-blend-mode: difference;
    color: white;
  }
  
  .isolate {
    isolation: isolate;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="bg-red"&gt;
    &lt;div class="blend"&gt;
      &lt;h2&gt;This text should &lt;span class="isolate"&gt;(This one shouldn't)&lt;/span&gt; be blended 
      &lt;/h2&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
