title: How change the color of the radio button
body: <p>Is it possible to change the background-color of a radio button by CSS ?
  I looked on the internet but I only find solutions in JS and I do not understand them necessarily. I tried this but it doesn't 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>input[type="radio"]:checked {
    background-color: red;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="sound-signal"&gt;
    Signal sonore :
    &lt;input type="radio" name="soundsignal" id="soundsignal" checked="checked"&gt;
    &lt;label for="soundsignal"&gt;Oui&lt;/label&gt;
    &lt;input type="radio" name="soundsignal"&gt;
    &lt;label for="soundsignal"&gt;Non&lt;/label&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
