CSS раскладное меню не закрывается после нажатия

/ 26 апреля 2018

Я создал простое раскладное меню.Когда я нажимаю на иконку меню, открывается меню.

Теперь, когда я нажимаю на любую опцию, она должна закрыться, чего не происходит.Ниже мой код в Codepen .

Пожалуйста, предоставьте решение, используя только CSS.Я не хочу использовать JS. 

body {
  margin: 0;
  padding: 0;
  /* make it look decent enough */
  background: #232323;
  color: #cdcdcd;
  font-family: "Avenir Next", "Avenir", sans-serif;
}

a {
  text-decoration: none;
  color: #232323;
  transition: color 0.3s ease;
}

a:hover {
  color: tomato;
}

#menuToggle {

Вы можете увеличить размер скрытого <input type="checkbox"/>, чтобы он охватывал все элементы меню.

Хотя это разрушает эффект наведения мыши.

В противном случае вы должны использовать JavaScript.

  margin: 0;

}

a {
  text-decoration: none;
  color: #232323;
  transition: color 0.3s ease;
}

a:hover {
  color: tomato;
}

#menuToggle {

ОБНОВЛЕНИЕ:

Используя javascript, довольно легко добиться этого, сняв флажок на каждом<li> нажмите 

var $input = document.querySelector('input[type="checkbox"]');
var $$menuLinks = document.querySelectorAll('#menu li');

$$menuLinks.forEach(link => {
  link.addEventListener('click', function() {
    $input.checked = false;
  });
});
