Ajout de classes au code javascript onhover

Question

Actuellement, dans ma page, j'ai un script externe, qui fait que le texte dans la div "contact" change de couleur en fonction de l'élément "item" qui est survolé. Maintenant, je souhaite que ce ne soit pas seulement la div "contact", qui change de couleur mais aussi la div "menu" et la div "curriculum", ainsi que toute autre div, que je pourrais avoir envie d'ajouter plus tard. J'ai essayé de modifier mon javascript actuel afin de le faire, en ajoutant une autre variable let et en l'incluant dans le script. Cependant, rien n'a fonctionné jusqu'à présent. Je suis en train d'étudier mon javascript, pour pouvoir faire ces changements. Mais peut-être que quelqu'un pourrait me dire comment faire cela de la manière la plus propre possible ?

let $contact = $('#contact');

$('.item').hover(function() {
  let $target = $($(this).data('target')).toggleClass('hide_default');
  $('#contact').css('color', $target.css('color'));
});

      <br> I love my childhood memories, which were filled with colors, papirs, pencils and handcraft works. I developed an obsession towards various kinds of creative fields: photography, developing analogue photos, architecture, - percieving buildings
      as shapes, volumes and combination of materials, as well as learning to look upon typography as shapes with entrenched characthers. When I realized that graphic design brought together all of these different passions of mine, I pursued it with enthusiasm.

Answer 1

Au lieu d'appliquer le CCS uniquement sur l'élément #contact, vous pouvez appliquer le sélecteur jQuery sur plusieurs éléments comme ceci :

$("#contact, div, span, .whateverClass").css('color', #colorYouWant);
