Question

当我检查并将其放置到iPhone x等移动设备上时，我的导航栏当前显示如下：https://gyazo.com/7d0b28abdc172c13208d64b1cdde2559

但是，我希望它在移动设备中显示为：https://gyazo.com/5f67b6888177c20b2e087838f29470b0 并使其打开，就像单击按钮时一样。

使它看起来像我希望在CSS中不显示任何内容，但这意味着当您单击按钮以显示它时，我的HTML和CSS如下所示

CSS：

 @media screen and (max-width:640px){
        body{
            overflow-x: hidden;
        }
        .nav-links{
            position: absolute;
            right: 0px;
            height: 92vh;
            top: 8vh;
            background-color: #5d4954;
            display: flex;
            flex-direction: column;
            align-items: center;
            width: 50%;
            transform: translateX(100%);
            display: none;
        }        
        .nav-links li{
            opacity: 0;
        }

        .burger{
            display: block;
        }
    }
    .nav-active{
        transform: translateX(0%);
        transition: transform 0.5s ease-in;
    }

HTML：

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width">
    <meta name="author" content="Lewis Haddon">
        <title>Business website</title>
        <link rel="stylesheet" href="./css/test2.css" type="text/css">
   </head>

   <body>
       <nav>
           <div class="logo">
               <h4>The Nav</h4>
           </div>
           <ul class="nav-links">
               <li><a href="">Home</a></li>
               <li><a href="">S3</a></li>
               <li><a href="">RS6</a></li>
           </ul>
           <div class="burger">
               <div class="line1"></div>
               <div class="line2"></div>
               <div class="line3"></div>
           </div>
       </nav>

       <script src="app.js"></script>
   </body>

</html>

Java：

  const navSlide = () => {
  const burger = document.querySelector('.burger');
  const nav = document.querySelector('.nav-links');
  const navLinks = document.querySelectorAll('.nav-links li');

    //Toggles the nav bar
burger.addEventListener('click', () => {
    nav.classList.toggle('nav-active');

    //animates the links
     navLinks.forEach((link, index) => {
        if (link.getElementsByClassName.animation) {
            link.style.animation = ``;
        } else {
             link.style.animation = `navLinkFade 0.5s ease forwards ${index /7 + 0.5}s`;
        }
     });
     //burger animation
     burger.classList.toggle('toggle');

    });


}

navSlide();

请提供任何帮助：）

Answer 1

使用visibility: hidden;作为CSS。

您可以使用@media查询来检测客户端是否在移动环境中使用。

@media screen and (max-width: 500px) {
    #navID { visibility: hidden; }
}

Answer 2

在您的CSS中添加此代码，可以将移动视图的像素从320更改为350或300

@media(max-width: 320px) {
    nav{
        display: none;
    }
}

Answer 3

将其用于右侧的切换器：

尝试在上面的代码中插入html和jQuery而不是css。

这会容易得多：-）
