隱藏導覽列、打開導覽列

<html>
<head>
<title>導覽列</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<style>
.phoneli01 {
	width:250px;
	height:50px;
	text-align:center;
	line-height:50px;
	list-style-type:none;

<body>

<button id="o">O</button>
<button id="x">X</button>


<ul id="nav">
	<li class="phoneli01"><a class="one" href="#">首頁</a></li>
	<li class="phoneli01"><a class="one" href="#">最新消息</a></li>
	<li class="phoneli01"><a class="one" href="#">關於我們</a></li>
	<li class="phoneli01"><a class="one" href="#">聯絡我們</a></li>
	<li class="phoneli01"><a class="one" href="#"> Q & A</a></li>

<script>
$(document).ready(function(){

套用fontawesome的icon
<link href="fontawesome/fontawesome-free-6.0.0-web/fontawesome-free-6.0.0-web/css/all.css" rel="stylesheet">
<body>
<i class="fa-solid fa-bars"></i>
<i class="fa-solid fa-bars" style="font-size:48px;"></i>
<i class="fa-solid fa-bars" style="font-size:60px;color:red;"></i>

 

JQuery使用toggle()來開關(隱藏,開啟)

$("#nav").toggle();

完整程式碼:
<html>
<head>
<title>導覽列</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<link href="fontawesome/fontawesome-free-6.0.0-web/fontawesome-free-6.0.0-web/css/all.css" rel="stylesheet">
<style>
.phoneli01 {
width:250px;
height:50px;
text-align:center;

<ul id="nav">
<li class="phoneli01"><a class="one" href="#">首頁</a></li>
<li class="phoneli01"><a class="one" href="#">最新消息</a></li>
