bootstrap 4 tabs animation

The problem here is that .tab-panes without the .active class have display: none; set, but css transition does not work when transitioning from that state.

So you have two options here:

  • You could override how Bootstrap handles the inactive tabs, and instead of using the display property, you could use –let’s say– the visibility property to show/hide the tabs. Just make sure display: block is enforced.
  • The easier solution though would be simply to use css animation with key-frames, as opposed to css transition. The former solution works with display; none as well. The example below is an example for this.

.tab-pane.active {
    animation: slide-down 2s ease-out;
}

@keyframes slide-down {
    0% { opacity: 0; transform: translateY(100%); }
    100% { opacity: 1; transform: translateY(0); }
}
<nav id="myTab" class="nav nav-tabs" role="tablist">
    <a class="nav-item nav-link active" id="nav-home-tab" data-toggle="tab" href="#nav-home" role="tab" aria-controls="nav-home" aria-selected="true">Home</a>
    <a class="nav-item nav-link" id="nav-profile-tab" data-toggle="tab" href="#nav-profile" role="tab" aria-controls="nav-profile" aria-selected="false">Profile</a>
    <a class="nav-item nav-link" id="nav-contact-tab" data-toggle="tab" href="#nav-contact" role="tab" aria-controls="nav-contact" aria-selected="false">Contact</a>
</nav>

<div class="tab-content" id="nav-tabContent">
    <div class="tab-pane active" id="nav-home" role="tabpanel" aria-labelledby="nav-home-tab">
        Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Here is the better solution using transition instead of animation

.tab-pane.fade {
  transition: all 0.2s;
  transform: translateY(1rem);
}

.tab-pane.fade.show {
  transform: translateY(0rem);
}
