You can use pure CSS using box-shadow as follow:
.item::after{
content: '';
position: absolute;
top: 0;
right: 0;
height: 100%;
width: 100%;
-webkit-box-shadow: inset -5px 0px 0px 0px rgba(255,255,255,1);
-moz-box-shadow: inset -5px 0px 0px 0px rgba(255,255,255,1);
box-shadow: inset -5px 0px 0px 0px rgba(255,255,255,1);
}
