bottom shadow triangle figure

I need a box shadow at the bottom with a triangle like effect. I have a box shadow CSS but can't make a triangle effect. See attached

html:

<div class="card players m-0 rounded border border-gray mb-0">
    <div class="t-wrap d-flex justify-content-center">
        <div id="triangle"></div>
    </div>
</div>

css:

#triangle {
    width: 0;
    height: 0;
    border-left: 250px solid transparent;
    border-right: 250px solid transparent;
    border-bottom: 30px solid rgb(255 255 255);
    z-index: 1;
}

#triangle:before {
    transform: rotate(-135deg) skewX(-45deg) scale(1.414,.707) translate(0,-50%);
}

#triangle:after {
    transform: rotate(135deg) skewY(-45deg) scale(.707,1.414) translate(50%);
}

#triangle,
#triangle:before,
#triangle:after {
    border-top-right-radius: 30%;
}

#triangle:before,
#triangle:after {
    content: '';
    position: absolute;
    background-color: inherit;
}
