title: how to add html to another html. Tried everything but still does not work
body: <p>I am trying to add subscribe.html to index.html.
  I researched everywhere and used all the forms but it does not work. Does not show any content in my subscribe.html.
  I will be glad if you guys can let me know how to handle this problem.
  This is the code in index.html.</p>
  <pre><code> &lt;footer&gt;
        &lt;script&gt;
          subscribe.html;
        &lt;/script&gt;
        &lt;h3&gt;Subscribe &amp;nbsp; &amp;nbsp; NewsLetter &amp;nbsp; &amp;nbsp; Help &amp;nbsp; &amp;nbsp; Instagram &amp;nbsp;&lt;/h3&gt;
      &lt;/footer&gt;
      &lt;object data=&quot;html/subscribe.html&quot;&gt; &lt;/object&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  <p>this is code in subscribe.html</p>
  <pre><code>&lt;p&gt;hey&lt;/p&gt;
  &lt;!-- modify this form HTML and place wherever you want your form --&gt;
  
  &lt;form action=&quot;https://formspree.io/mjvazzkn&quot; method=&quot;POST&quot;&gt;
    &lt;label&gt;
      Your email:
      &lt;input type=&quot;text&quot; name=&quot;_replyto&quot; /&gt;
    &lt;/label&gt;
    &lt;label&gt;
      Your message:
      &lt;textarea name=&quot;message&quot;&gt;&lt;/textarea&gt;
    &lt;/label&gt;
  
    &lt;!-- your other form fields go here --&gt;
  
    &lt;button type=&quot;submit&quot;&gt;Send&lt;/button&gt;
  &lt;/form&gt;
  </code></pre>
