Answer 1

I had this problem myself and found the solution. Bootstrap uses the following CSS media query to disable the modal fade animation (and a number of other transitions and animations) in certain circumstances:

@media (prefers-reduced-motion: reduce) {
    .fade {
        transition: none;
    }
}

According to MDN, "The prefers-reduced-motion CSS media feature is used to detect if the user has requested that the system minimize the amount of animation or motion it uses." They have instructions there for changing this on various operating systems. (The Windows method worked for me: Settings > Ease of Access > Display > Show animations [On])

Please try to this format for design & modal work.

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">

</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
 <div class="modal-dialog" role="document">
   <div class="modal-content">
    <div class="modal-header">
     <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
      <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
       ...
      </div>
      <div class="modal-footer">
      <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      <button type="button" class="btn btn-primary">Save changes</button>

The seccond part, the modal part mus not be on the body. Move it just below the head ends, and before the body tag start.

<head>
.... //heade code here
</head>
MODAL HERE
<body>....

<button  type="button"
class="btn btn-info glyphicon glyphicon-plus"
data-toggle="modal"
data-target="#myModal{{$parent.$parent.$index}}{{$index}}">
    Add URL
</button>
...more code here
</body>
