jQuery question about adding/removing classes?

Question

css

Hello. It is necessary to implement color selection, let's say there are 5 blocks\checkboxes, only one can be selected. How to implement such a mechanism in jquery? That is, you click on one checkbox, it is selected, you click on another, it is selected, and the previous one is removed. It is necessary to add a class, since the checkboxes are custom. addClass, removeClass, toggleClass - I know, but I find it difficult to implement such a mechanism.

Answer 1

$(".checkbox").click(function(){
  $(this).addClass("selected")
      .siblings(".checkbox").removeClass("selected");
});
