picker.inline.css

.picker__holder,
.picker--opened .picker__holder {
  max-height: 25em;
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
  filter: alpha(opacity=100);
  -moz-opacity: 1;
  opacity: 1;
  border-top-width: 1px;
  border-bottom-width: 1px;
  -webkit-transform: translateY(0) perspective(600px) rotateX(0);
          transform: translateY(0) perspective(600px) rotateX(0);
  -webkit-transition: -webkit-transform 0.15s ease-out, opacity 0.15s ease-out, max-height 0s, border-width 0s;
          transition: transform 0.15s ease-out, opacity 0.15s ease-out, max-height 0s, border-width 0s;
  box-shadow: none;
}
