Retractable menu that does not close

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

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

I know html and css. Javascript I’m having contact with it now so I don’t really know anything about.

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;
                text-align: center;
                background-color:  #5b8594;
                color: #fff;
                cursor: pointer;
                transition: all .4s;
                left: 300px;
                top: 0;
            }

            .menu-icon:hover{
                background-color:  #fff;
                color: #5b8594;
                cursor: pointer;
                transition: all .4s;
                left: 300px;
                top: 0;
            }

            #check {
                position: absolute;
                z-index: 100;
            }

            .menu {
                height: 100%;
                position: fixed;
                background-color: #222;
                top:0;
                overflow: hidden;
                transition: all .2s;
            }

            #principal {
                width: 300px; 
                left: -300px;
            }

            ul {
                list-style: none;
            }

            ul li a{
                display: block;
                font-size: 18px;
                font-family: 'Arial';
                padding: 10px;
                border-bottom: solid 1px #000;
                color: #ccc;
                text-decoration: none;
                transition: all 0.2s;
            }

            ul li span{
                float: right;
                padding-right: 10px;
            }

            ul li a:hover{
                background-color: #5b8594;

            }

            .voltar{
                margin-top: 60px;
                background-color: #111;
                border-left: solid 5px #444;

            }

            .backg {
                width: 100%;
                height: 100%;
                left: 0;
                top:0;
                position: fixed;
                background-color: rgba(0,0,0,.6);
                display: none;
            }

            #check:checked ~.backg{
                display: block;
            }

            #check:checked ~ #principal{
                transform: translateX(300px);
            }

Have the JS to put here too? So someone could test with the Snippet.

So I didn’t use JS, there’s some way to do it without?

I would like a solution using JS or jQuery?

It would be in jQuery itself.

Hello,

For this type of menu you can only with CSS, with the pseudo-class:Focus, because it applies to the element when it is clicked, and when we click outside or on another element, it loses the state of focus, thus removing the 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>
