title: How to make a text in font/weight style bold in JavaScript
body: <p>I need change the font weight for a text element in JavaScript:</p>
  
  <p>My code here does not work:</p>
  
  <pre><code>var btn = document.getElementById('accessibilityButton');
  btn.innerHTML = 'Default Text';
  btn.innerHTML.style.fontWeight = 'bold';
  </code></pre>
  
  <p>What am I doing wrong?</p>
  
  <p>Please note that I don't want to use any libraries (jQuery et. al.) and am looking for a plain JS solution.</p>
