Convert horizontal tab from Bootstrap 3 to Bootstr

I have a code from bootsnip to make horizontal Bootstrap tabs with style like material. I'm having trouble converting it to Bootstrap 4. I'm focusing on changing the style of li to .nav-item and a to .nav-link in css. but the result is different.

this the code using Bootstrap 3: horizontal tab

and this is my code use Bootstrap 4:

.no-style{
	text-decoration:none!important;
}
.nav-tabs {
	background-color:#333;
	border-bottom: 2px solid #DDD; 
}
.nav-tabs > .nav-item > .nav-link.active, .nav-tabs > .nav-item > .nav-link.active:focus, .nav-tabs > .nav-item > .nav-link.active:hover {
	border-width: 0;
}
.nav-tabs > .nav-item > .nav-link {
	border: none; 
	color: rgba(255,255,255,.6);
}

.nav-tabs > .nav-item > .nav-link.active, .nav-tabs > .nav-item > .nav-link:hover {
	border: none; 
	color: rgba(255,255,255,1); 
	background: transparent;
}

.nav-tabs > .nav-item > .nav-link::after {
	content: ""; 
	background: #4285F4; 
	height: 2px; 
	position: absolute; 
	width: 100%; 
	left: 0px; 
	bottom: -1px; 
	transition: all 250ms ease 0s; 
	transform: scale(0); 
}
.nav-tabs > .nav-item > .nav-link.active::after, .nav-tabs > .nav-item:hover > .nav-link::after { 
	transform: scale(1); 
}

In order for the positioning on an ::after element to work, the parent element must be positioned. I fixed that.
