Bootstrap 4 tooltip arrow shadow styling

This is the tooltip's arrow without shadow:

enter image description here

I'm trying to shadow it but since the arrow is made out of borders I've been unable to render a proper result. Getting the following:

Any ideas how to integrate the arrow part's shadow to the rest of the tooltip? (Snippet below)

Checked the following and some others but couldn't find a shadow specific scenario.

Thank you.

$('[data-toggle="tooltip"]').tooltip('show');
html body {
  background: #eee;
}

button.btn {
  margin-top: 100px;
}

.tooltip-inner {
  background-color: white !important;
  color: gray !important;
  border-radius: 0 !important;
  box-shadow: 2px 2px 4px 0px rgba(161, 161, 161, 1);
}

.bs-tooltip-right .arrow::before {
  border-right-color: white !important;
  box-shadow: 2px 2px 4px 0px rgba(161, 161, 161, 1);
}

Solution

  • You can achieve this with a little css magic and applying the styling to the ::after pseudo element. Added the shadow there and dropped the z-index to -1 to sit behind and give the desired effect.

    $('[data-toggle="tooltip"]').tooltip('show');
    html body {
  background: #eee;
  margin: 30px;
}

.tooltip-inner {
  background-color: white !important;
  color: gray !important;
  border-radius: 0 !important;
  box-shadow: 2px 2px 4px 0px rgba(161, 161, 161, 1);
}

.bs-tooltip-right .arrow::before {
  border-right-color: white !important;
}

.bs-tooltip-right .arrow::after {
  content: "";
  position: absolute;
  left: 100%;
  z-index: -1;
  border: 5px solid #fff;
  transform-origin: 0 0;
  transform: rotate(45deg);
  box-shadow: 2px 2px 4px 0px rgba(161, 161, 161, 1);
}
