I have a retractable menu, but I can only get it open but not close.

I need it to close when clicking anywhere on the screen outside the menu.

I know about html and css. Javascript is getting in touch with it now so I do not know how to say anything about it.

HTML:

  <body>
    <input type="checkbox" id="check">
    <label for="check" class="menu-icon">&#9776;</label>
        <div class="backg"></div>
        <nav class="menu" id="principal">
            <ul>
                <li><a href="" class="voltar">Voltar</a></li>
                <li><a href="">Home</a></li>
                <li><a href="">Fórum</a></li>
                <li><a href="">Cursos <span>+</span></a></li>
                <li><a href="">Sobre</a></li>
                <li><a href="">Contato <span>+</span></a></li>
            </ul>
        </nav>

  </body>
</html>

CSS:

            * {
                margin: 0;
                padding: 0;
            }

            header {
                width: 100%;
                height: 50px;
                top: 0;
                left: 0;
                background-color: #5b8594;
                position: fixed;    
            }

            .menu-icon{
                position: fixed;
                font-size: 25px;
                font-weight: bold;
                padding: 5px;
                width: 40px;
                height: 40px;

                left: 300px;
                top: 0;
            }

            .menu-icon:hover{
                background-color:  #fff;
                color: #5b8594;

Hello,

For this type of menu you only get CSS with pseudo-class: focus, as it applies to the element when it is clicked, and when we click outside or another element, it loses its focus state, style applied. Example:

body {
  font-family: "Open Sans", sans-serif;
}
.popup-menu {
  background: #f5f5f5;
  display: none;
  margin: 0;
  padding: 15px;
  width: 150px;
}
.bt-menu:focus + .popup-menu {
  display: block;
}
.popup-menu li {
  list-style: none;
}
.popup-menu a {
  display: block;
  text-align: center;
  text-transform: uppercase;
  padding: 5px 0;
}
.popup-menu a:hover {
  background: #fff;
}

<button class="bt-menu">Menu</button>
<ul class="popup-menu">
  <li><a href="">Item 1</a></li>
  <li><a href="">Item 2</a></li>
  <li><a href="">Item 3</a></li>
  <li><a href="">Item 4</a></li>
</ul>
