title: How should i center my non bootstrap modal?
body: <p>I wish to center vertically and horizontally my non-bootstrap modal.</p>
  <p>How should I go on?</p>
  <p>I have given HTML CSS and JS code which I have used for the same.</p>
  <p>I have just put in random text at the moment. There is actually gonna be a signup form.</p>
  <p>This is all my Code for the modal:</p>
  <pre><code>&lt;!-- The Modal --&gt;
      &lt;div id=&quot;myModal&quot; class=&quot;modal center&quot;&gt;
        &lt;!-- Modal content --&gt;
        &lt;div class=&quot;modal-content&quot;&gt;
          &lt;div class=&quot;modal-header&quot;&gt;
            &lt;span class=&quot;close&quot;&gt;&amp;times;&lt;/span&gt;
            &lt;h2&gt;Modal Header&lt;/h2&gt;
          &lt;/div&gt;
          &lt;div class=&quot;modal-body&quot;&gt;
            &lt;p&gt;Some text in the Modal Body&lt;/p&gt;
            &lt;p&gt;Some other text...&lt;/p&gt;
          &lt;/div&gt;
          &lt;div class=&quot;modal-footer&quot;&gt;
            &lt;h3&gt;Modal Footer&lt;/h3&gt;
          &lt;/div&gt;
        &lt;/div&gt;
      &lt;/div&gt;
  </code></pre>
