动画汉堡包导航

Question

我正在为我的网站创建一个完整的页面导航阴影，以便它在所有设备上都是一样的。目前，我有两个按钮，一个用于查看阴影，一个用于不查看。我想知道，如果有一个按钮始终存在，那么它可以被动画化，会不会更好？我的目标是类似于 squeeze 动画 此处 但我不确定如何在两个按钮上制作动画，而不是只在一个按钮上制作--或者你如何从头开始创建它。

这是我正在做的工作。

const navButtons = document.querySelectorAll('button.nav-action');
const siteNav = document.querySelector('.site-nav');

function onClick(event) {
  siteNav.classList.toggle('active');
}

navButtons.forEach(button => button.addEventListener('click', onClick));

.site-header {
    height: 80px;
    background-color: #FFFFFF;
    display: inline-flex;
    position: fixed;
    top: 0;
    left: 0;
    right: 0;
    z-index: 1;
    box-shadow: 0px 0.5px 10px #000000;
}

.site-header-fill {
    height: 80px;
}

.site-logo-container {
    height: 60px;
    margin-left: 20px;
    margin-right: auto;
    margin-top: 10px;
    margin-bottom: 10px;
    display: block;
    float: left;
}

.site-logo {
    height: 60px;
    width: auto;
    float: left;
}

.site-nav-action-container {
    height: 50px;
    width: 50px;
    max-width: 50px;
    margin-left: 10px;
    margin-right: 10px;
    margin-top: 15px;
    margin-bottom: 15px;
    display: block;
    float: right;
    text-align: right;
}

.site-nav {
	height: 100%;
	left: 0px;
	position: fixed;
	top: 0px;
	width: 100%;
	background: #3399ff;
	z-index: 2;
	display: none;
}

.site-nav.active {
    display: block;
}

.site-nav-content {
	width: 20%;
	position: absolute;
	left: 50%;
	top: 50%;
	-webkit-transform: translate(-50%, -50%);
	transform: translate(-50%, -50%);
}

@media only screen and (max-width: 500px) {
.site-nav-content {
    width: auto;
    position: absolute;
    left: 50%;
    top: 50%;
    -webkit-transform: translate(-50%, -50%);
    transform: translate(-50%, -50%);
}
}

.site-nav-pages {
    text-align:center;
}

.nav-action {
    height: 50px;
    width: 50px;
}

<div class="site-header ">
   <div class="site-logo-container">
      <img class="site-logo" src="https://via.placeholder.com/1000x300" alt="Logo">
   </div>
   <div class="site-nav-action-container">
      <button class="nav-action">
         <p>☰</p>
      </button>
   </div>
</div>
<div class="site-nav">
   <div class="site-nav-action-container">
      <button class="nav-action">
         <p>×</p>
      </button>
   </div>
   <div class="site-nav-content">
      <div class="site-nav-pages">
         <p>Page 1</p>
         <p>Page 2</p>
         <p>Page 3</p>
         <p>Page 4</p>
         <p>Page 5</p>
      </div>
   </div>
</div>

目前，阴影现在的功能是可见或不基于按钮按下，但我想知道，如果有一个按钮是去的方式，或者如果放置图标外的按钮将工作最好。

理想的情况是，当阴影从顶部显示时，汉堡包会产生动画，但一旦按钮的合理方法被整理出来，我就会在这方面下功夫。任何帮助将是感激的，因为我显然不知道我在这里做什么。

先谢谢你了。

你可以用在☰来×效果。你可以自己写所有的线条标签.第一个代码片段是我经常使用的动画，第二个是我认为你想要的动画。我把两个都装了，所以你想用什么就用什么。

const navButtons = document.querySelectorAll('button.nav-action');
const siteNav = document.querySelector('.site-nav');

function onClick(event) {
  siteNav.classList.toggle('active');
}

navButtons.forEach(button => button.addEventListener('click', onClick));


const menuIcon = document.querySelector(".menu-icon");
menuIcon.addEventListener("click", () => {
  menuIcon.classList.toggle("toggle")
  siteNav.classList.toggle('active');
})
