Most simple way to change CSS is via integrated WP Customizer, so login as admin and then open wanted page, click on Customize as on screenshot:

Then click on Additional CSS:

Now you can enter custom CSS:

Example for change heart icon with other icon in favorites addon

Some CSS knowledge is require for that, so for example I will use Firefox Console, you can also use Chrome Developer Console to detect some CSS, example:

So we can detect specific custom CSS, sometimes you may change CSS a bit:

.wdk-favorites-actions .fa.fa-heart-o:before {
  content: "\f004";  // icon unselected
}

.wdk-favorites-actions .fa-heart::before {
  content: "\f004"; // icon selected
}

icons codes can be found on this https://fontawesome.com/search
