title: Bootstrap: $('#myModal').modal('show'); causes screen to go black
body: <p>At the end of my body tag, I have a modal:</p>
  
  <pre><code>&lt;div class="portfolio-modal mfp-hide" id="myModal"&gt;
    &lt;div class="portfolio-modal-dialog bg-white"&gt;
      &lt;a class="close-button d-none d-md-block portfolio-modal-dismiss" href="#"&gt;
        &lt;i class="fa fa-3x fa-times"&gt;&lt;/i&gt;
      &lt;/a&gt;
      &lt;div class="container text-center"&gt;
        &lt;div class="row"&gt;
          &lt;div class="col-lg-8 mx-auto"&gt;
            &lt;hr class="star-dark mb-5"&gt;
          &lt;/div&gt;
        &lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>And at the beginning of my body tag, I have a script. In this script, I'm trying to show a modal when a google maps marker is clicked. However, when it is clicked, my website crashes with a dim-black screen and no modal shows.</p>
  
  <pre><code>window.google.maps.event.addListener(marker, 'click', function () {
                 // $("#myModal").removeClass("in");
                 //$("#myModa").remove();
                 //$('body').removeClass('modal-open');
                 // $('body').css('padding-right', '');
                 // $('#myModal').modal('show');
                 // $('.myModal').modal('show');
  
                  $('#myModal').modal('show');
  
              });
  </code></pre>
  
  <p>Interestingly, my modal shows perfectly fine when accessing via <code>href</code> here:</p>
  
  <pre><code>&lt;div class="col-md-3"&gt;
          &lt;a class="portfolio-item d-block mx-auto" href="#myModal"&gt;
            &lt;div class="portfolio-item-caption d-flex position-absolute h-100 w-100"&gt;
            &lt;/div&gt;
          &lt;/a&gt;
        &lt;/div&gt;
  </code></pre>
  
  <p>This has to be some type of bug within the Bootstrap Freelancer template. I've read other posts saying that others fixed a similar issue by editing .css files. </p>
  
  <p>Here is my bootstrap.css code</p>
