Enqueue Google fonts in WordPress theme

functions.php

/**
  * Enqueue custom fonts using protocol relative URL.
  *
  * Syntax: wp_enqueue_style( $handle, $src, $deps, $ver, $media );
  * Ensure $handle is unique to prevent conflicts with plugins
  *
  * Note(s): The pipe (|) operator is used to load multiple typefaces in a single call. We also only load the weights we want   * by comma seperating them, instead of loading every available weight.
