Vertically Centered Modal

Dear La Roze,

Could you please provide me with the code which is not working to you?

I have tried to reproduce it with the following code, but for me there's no strange scrollbar in the middle of the screen / modal.

.html:

  <button type="button" mdbBtn color="primary" class="relative waves-light" (click)="basicModal.show()" mdbWavesEffect>Launch demo modal</button>

   <div mdbModal #basicModal="mdbModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myBasicModalLabel" aria-hidden="true">
     <div class="modal-dialog modal-dialog-centered" role="document">
       <div class="modal-content">
         <div class="modal-header">
           <button type="button" class="close pull-right" aria-label="Close" (click)="basicModal.hide()">
             <span aria-hidden="true">×</span>
           </button>
           <h4 class="modal-title w-100" id="myModalLabel">Modal title</h4>
         </div>
         <div class="modal-body">
           ...
         </div>
         <div class="modal-footer">
           <button type="button" mdbBtn color="secondary" class="waves-light" aria-label="Close" (click)="basicModal.hide()" mdbWavesEffect>Close</button>
           <button type="button" mdbBtn color="primary" class="relative waves-light" mdbWavesEffect (click)="secondModal.show()">Save!</button>
         </div>
       </div>
     </div>
   </div>


   <div mdbModal #secondModal="mdbModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myBasicModalLabel" aria-hidden="true">
     <div class="modal-dialog modal-dialog-centered" role="document">
       <div class="modal-content">
         <div class="modal-header">
           <button type="button" class="close pull-right" aria-label="Close" (click)="secondModal.hide()">
             <span aria-hidden="true">×</span>
           </button>
           <h4 class="modal-title w-100" id="myModalLabel">Modal title</h4>
         </div>
         <div class="modal-body">
           ...
         </div>
         <div class="modal-footer">
           <button type="button" mdbBtn color="secondary" class="waves-light" aria-label="Close" (click)="secondModal.hide()" mdbWavesEffect>Close</button>
           <button type="button" mdbBtn color="primary" class="relative waves-light" mdbWavesEffect>Save!</button>
         </div>
       </div>
     </div>
   </div>

Best Regards, Damian
