JavaScript makes the page work functionally. At last, create a JavaScript file with the name of script.js, and remember that you've got to make a file with a .js extension.


$('button').click(function(){
  $('.alert').addClass("show");
  $('.alert').removeClass("hide");
  $('.alert').addClass("showAlert");
  setTimeout(function(){
    $('.alert').removeClass("show");
    $('.alert').addClass("hide");
  },5000);
});
$('.close-btn').click(function(){
  $('.alert').removeClass("show");
  $('.alert').addClass("hide");
});
