Question

我正在为我的网站创建一个完整的页面导航阴影，以便在所有设备上都相同。目前，我有两个按钮，一个用于查看阴影时的按钮，另一个用于不显示阴影时的按钮。我想知道总是有一个按钮以便可以设置动画会更好吗？我的目标是像squeeze动画here这样的东西，但是我不确定如何在两个按钮之间进行动画处理，而不仅仅是一个-或者如何从中创建动画从头开始。

这就是我正在使用的东西；

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，根据按下的按钮，阴影现在可以显示或不显示，但是我想知道是否要使用一个按钮，或者将图标放在按钮之外是否效果最好。

理想情况下，当从顶部露出阴影时，汉堡包会动画，但是一旦对按钮进行了明智的选择，我将继续努力。任何帮助将不胜感激，因为我显然不知道自己在这里做什么。

谢谢。

您可以使用☰到×效果。您可以自己编写所有行标签。第一个代码段是我经常使用的动画，第二个代码段是我认为想要的动画。我同时安装了两者，因此您可以使用任何想要使用的东西。
