title: How to implement "fill in the blanks" ? reactjs
body: <p>How to implement <em>&quot;fill in the blanks&quot;</em> in reactjs. I have tried the code below, but I think its not a good idea, because they can inspect element of it.</p>
  <p>Is there a better implementation of this? And also is it possible to display a hint (at least one letter in the blank)? thanks.</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>.blank {
    color: transparent;
    border-bottom: 1px solid black;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div&gt;Nunc ac &lt;span class="blank"&gt;imperdiet&lt;/span&gt; justo&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
