Remove background from selected dates | flatpickr.js

How can I remove this background from inRange items?

.flatpickr-day.startRange,.flatpickr-day.endRange {
    background: #353535;
    border: 1px solid #D2D2D2;
    border-radius: 8px;
}
.flatpickr-day.inRange {
    background: #353535;
    border: none;
    border-radius: 8px;
}

Solution:

.flatpickr-day.inRange {
    background: #353535;
    border: none;
    border-radius: 8px;
    -webkit-box-shadow: none;
    box-shadow: none;
 }
