title: Different opacity element within a div
body: <p>I need to change opacity of an element within a div, to give it more opacity than the parent. How can I give the <code>.solid</code> a full opacity (<code>="1"</code>), without pre-processors?</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>.half-faded {
    opacity:0.3;
    border:1px solid black;
    width:200px;
    display:flex;
    justify-content:space-around;
  }
  .solid {
    opacity:1; /* doesn't help */
    opacity:2; /* twice doesn't help */
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="half-faded"&gt;
    &lt;span class="one"&gt;One&lt;/span&gt;
    &lt;span class="two"&gt;Two&lt;/span&gt;
    &lt;span class="solid"&gt;Solid&lt;/span&gt;
    &lt;span class="four"&gt;Four&lt;/span&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
