      </div>
    </div>
    <!-- /.modal-content -->
  </div>
  <!-- /.modal-dialog -->
</div>
<!-- /.modal -->

CSS:

.modal-body {
  max-height: calc(100vh - 210px);
  overflow-y: auto;
}

.loader {
  border: 16px solid #f3f3f3;
  /* Light grey */
  border-top: 16px solid #3498db;
  /* Blue */
  border-radius: 50%;
  width: 120px;
  height: 120px;
  animation: spin 2s linear infinite;
}

@keyframes spin {
  0% {
    transform: rotate(0deg);
  }
  100% {
    transform: rotate(360deg);
  }
}

Problem:

It is showing the scroll bar alone while loading makes animation. How can I fix this ?

html5 css3 bootstrap-3 modal

  • it is necessary to scrollbar ?

  • Yes, after loading, it will load the contents ...

  • And where is the function of loading ? Put here on the question, do not need to use external websites, just paste the code select it and press CTRL+K to format.

  • I don’t call the function loading, itself is in html. After returning the ajax function, I do it myself hide to hide animation loading. It seems that the problem is in css.

  • @Souza Post edited, see !

You can hide the overflow-y as long as it is loading is being displayed when hiding the loading define the overflow-y as auto again.

$('#myModal .modal-body').on('scroll', function() {
    console.log('scroll y');
});
// oculta o overflow-y
$('#myModal .modal-body').css({
  	'overflow-y': 'hidden'
  });
/// Apenas para simular
setTimeout(function(){
  $(".loader").hide(); // Oculta o loading
  $('#myModal .modal-body').html('<p>Paragrafo</p><p>Paragrafo</p><p>Paragrafo</p><p>Paragrafo</p><p>Paragrafo</p><p>Paragrafo</p><p>Paragrafo</p>');
  // Define o overflow-y como auto
  $('#myModal .modal-body').css({
  	'overflow-y': 'auto'
  })
}, 5000);
.modal-body {
  max-height: calc(100vh - 210px);
  overflow-y: auto;
}

.loader {
  border: 16px solid #f3f3f3;
  /* Light grey */
  border-top: 16px solid #3498db;
  /* Blue */
  border-radius: 50%;
  width: 120px;
  height: 120px;
  animation: spin 2s linear infinite;
}

@keyframes spin {
  0% {
    transform: rotate(0deg);
  }
  100% {
    transform: rotate(360deg);
  }
}
