I have displayed the "a" tag as an inline-block so that it doesn't occupy the whole container width.

In your code, you forgot to add content property. And the hover is applied to the ::after selector of the "a" tag not the "a" tag itself. Here is the fix to your code.

a{
  display: inline-block;
  color: white;
  text-decoration: none;
}

a::after {
  display: block;
  content: '';
  border-bottom: solid 3px darkgreen;
  transform: scaleX(0);
  transition: transform 250ms ease-in-out;
}

a:hover::after{
    transform: scaleX(1);
}

a:active{
    color: darkgreen;
}

a:visited{
    color: white;
    text-decoration: none;
}
