• Add the below code in the custom CSS file (/src/css/custom.css)

/* nunito-sans-regular - latin */
@font-face {
  font-family: "Nunito Sans";
  font-style: normal;
  font-weight: 400;
  src: url("/fonts/nunito-sans-v6-latin/nunito-sans-v6-latin-regular.eot"),
    /* IE9 Compat Modes */
      url("/fonts/nunito-sans-v6-latin/nunito-sans-v6-latin-regular.eot?#iefix")
      format("embedded-opentype"),
    /* IE6-IE8 */
      url("/fonts/nunito-sans-v6-latin/nunito-sans-v6-latin-regular.woff2")
      format("woff2"),
    /* Super Modern Browsers */
      url("/fonts/nunito-sans-v6-latin/nunito-sans-v6-latin-regular.woff")
      format("woff"),
    /* Modern Browsers */
      url("/fonts/nunito-sans-v6-latin/nunito-sans-v6-latin-regular.ttf")
      format("truetype"),
    /* Safari, Android, iOS */
      url("/fonts/nunito-sans-v6-latin/nunito-sans-v6-latin-regular.svg#NunitoSans")
      format("svg"); /* Legacy iOS */
}
