give a background color to the pointer of popover bootstrap

Question

I want to give a background colour to the pointing element of a popover. How can I do so? jsfiddle for the code

.popover{
   background:rgba(128, 21, 21,0.8);
   font-weight: bold;
   border-radius: 2%;
}
.popover-body{
   background:rgba(128, 21, 21,0.8);
   color: #ffffff;
}

Custom color popover

After taking a look at bootstrap v4.1.3 css file:

The css your searching for is .popover .arrow::after css rule.
But changing this will change all popovers on your site.
So we want to choose the ones we select with a custom class. .custom in the example.

Example:

$(function() {
  let e = $('[data-toggle="popover"]').popover().data('bs.popover').getTipElement();
  console.log(e);
  $(e).addClass("custom");
});

.popover {}

.custom .popover-body {
  background-color: red;
}

.custom .popover-header {
  background-color: darkred;
}

.custom .arrow {}

.custom.popover .arrow::after {
  border-right-color: red;
}

<button type="button" class="btn btn-lg btn-danger custom" data-toggle="popover" title="Popover title" data-content="And here's some amazing content. It's very engaging. Right?">Click to toggle popover</button>

So the explanation is:

Use javascript to add a class to the popover (class is "custom" in exaple above)
Add your own css rules with higher specificity.
Remember to the correct styles. (its a css triangle)

Thanks a lot. It worked. Example of css triangle helped me in understanding the problem. — Achal Gupta, Aug 22 '18 at 12:37

If it's bootstrap tooltip pls try code i written below

.tooltip.top .tooltip-arrow {
    border-top-color: #870a17; /* or what ever color you want*/
}

but it will work only if it's bootstrap tooltip with top option if anything else you should have to give code.

If it is bootstrap then please search in CSS. There must be present class like .bs-popover-top .arrow::before.

Make changes in it or you can write your own similarly like below.[note : you can change class name as per your code]

.bs-popover-top .arrow::before{ border-top-color:#f00; }
