Below is just the essentials to show what I've tried:

/* CSS */
.tooltip-inner{
  background: rgba(0, 0, 0, 0.3);
  backdrop-filter: blur(10px);
}
.tooltip-inner::before{
  content: ''
  background: rgba(0, 0, 0, 0.3);
  backdrop-filter: blur(10px);
}
.tooltip-inner::after{
  content: ''
  background: rgba(0, 0, 0, 0.5);
  backdrop-filter: blur(15px);
}
.card{
  background: rgba(0, 0, 0, 0.5);
  backdrop-filter: blur(15px);
}
.card::before{
  content: ''
  background: rgba(0, 0, 0, 0.5);
  backdrop-filter: blur(15px);
}



<!-- HTML -->
<button 
  class='btn btn-primary' 
  data-bs-html = 'true' 
  data-bs-toggle  = 'tooltip'
  data-bs-title = '
    <div class="card">
      <div class="card-text">
        <div class="card-header">OK</div>
        <div class="card-body">OKOKOKOKOKOKOKOKO</div>
      </div>
    </div>
  '

  Neque porro quisquam est
</button>

What I've tried

Here are the things I've tried:

$(document).ready(() => {
  const tooltipTriggerList = document.querySelectorAll('[data-bs-toggle="tooltip"]')
  const tooltipList = [...tooltipTriggerList].map(tooltipTriggerEl => new bootstrap.Tooltip(tooltipTriggerEl).show())
})
.tooltip-inner {
  padding: 50px;
  background: rgba(0, 0, 0, .3);
  color: white;
  width: 100%;
}

.tooltip-inner:before {
  background: rgba(0, 0, 0, .3);
  backdrop-filter: blur(10px);
}

.card {
  background: rgba(0, 0, 0, .5);
  padding: 20px;
  backdrop-filter: blur(15px);
}

#blur {
  filter: blur(0px);
}

    or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical
    exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?" Section 1.10.33 of

Solution

  • View the generated source and you will see what is going on.

    Your .card is rendered inside of .tooltip-inner which is within .tooltip so your blur rule should be on .tooltip not .card. Additionally backdrop-filter: blur() does not work well when applied to an element that is not fully opaque. In your case the following rules will make content covered by the tooltip blurred:

    .tooltip.show {
    opacity: 1;
    backdrop-filter: blur(5px);
}
