Target the 2nd instance of a CSS Class

you can use nth-child pseudo classes for your requirement....

.media-link:nth-child(2) {
color:red;
}

There are two pseudo-selectors that accomplish what you're looking for.

.media-link:nth-child(2) {
  // here style 
}

or

.media-link:nth-of-type(2){
  // here style
}
