  <a href="https://jsfiddle.net/phmttrsh/" rel="nofollow">https://jsfiddle.net/phmttrsh/</a></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>#btn {
      font-size: 16px;
      height: 34px;
      width: 120px;
      border: 1px solid #20ACB3;
      text-align: center;
      line-height: 34px;
      background-color: #20ACB3;
      color: #ffffff;
      border-radius: 5px;
      transition: transform 200ms cubic-bezier(0.25, 0.39, 0.39, 2.01);
  }
  
   #btn:hover {
          cursor: pointer;
          transform: scale(1.05);
      }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id="btn"&gt;Click&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>When on hover on button the font color will also change very short time and it only happened on safari.</p>
  
  <p>Why this happened?</p>
