      <input type="checkbox" class="nav-check" id="navi-toggle">

      <label for="navi-toggle" class="nav-btn">
          <span class="nav-icon">&nbsp;</span>

              <li class="nav-item"><a href="#" class="nav-link">Home</a></li>
              <li class="nav-item"><a href="#" class="nav-link">About</a></li>
              <li class="nav-item"><a href="#" class="nav-link">Services</a></li>

这是一个 JavaScript 解决方案。所有代码都有注释。

var elementsArray = document.querySelectorAll('.nav-link'); /* create an array of your '.nav-link' li */

elementsArray.forEach(function(myBtn) {
    /*add a listener to every element of this array */
    myBtn.addEventListener("click", function(e) {
        e.preventDefault()/* prevent default link behaviour */
       document.getElementById("navi-toggle").checked = false; /* unchecked your checkbox */
    });
});

.nav-check {
  display: none; 
}

.nav-btn {
  background-color: #fff;

  width: 4rem;

  text-align: center;
  cursor: pointer; 
}
  
.nav-bg {

.nav-btn:hover .nav-icon::before {

.nav-check:checked + .nav-btn .nav-icon {
