探索App模板源码，它们如何助力快速开发？

App模板源码是一套预先设计好的应用程序框架，用于快速开发和部署移动应用。

创建一个移动应用模板源码可以涉及多个方面，包括前端和后端的开发，以下是一个基本的示例，展示了如何使用HTML、CSS和JavaScript创建一个简单的移动应用界面。

1. HTML (index.html)

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF8">
    <meta name="viewport" content="width=devicewidth, initialscale=1.0">
    <title>App Template</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <header>
        <h1>My App</h1>
    </header>
    <nav>
        <ul>
            <li><a href="#home">Home</a></li>
            <li><a href="#about">About</a></li>
            <li><a href="#contact">Contact</a></li>
        </ul>
    </nav>
    <main>
        <section id="home">
            <h2>Welcome to My App</h2>
            <p>This is a simple app template.</p>
        </section>
        <section id="about">
            <h2>About Us</h2>
            <p>Learn more about our app and team here.</p>
        </section>
        <section id="contact">
            <h2>Contact Us</h2>
            <p>Reach out to us through our contact form.</p>
        </section>
    </main>
    <script src="scripts.js"></script>
</body>
</html>

2. CSS (styles.css)

{
    boxsizing: borderbox;
    margin: 0;
    padding: 0;
}
body {
    fontfamily: Arial, sansserif;
    lineheight: 1.6;
}
header {
    backgroundcolor: #333;
    color: #fff;
    textalign: center;
    padding: 1rem;
}
nav {
    backgroundcolor: #444;
    color: #fff;
    padding: 1rem;
    overflow: hidden;
}
nav ul {
    liststyle: none;
}
nav ul li {
    display: inline;
    marginright: 1rem;
}
nav ul li a {
    color: #fff;
    textdecoration: none;
}
main {
    padding: 2rem;
}
section {
    marginbottom: 2rem;
}
section h2 {
    marginbottom: 1rem;
}

3. JavaScript (scripts.js)

document.addEventListener('DOMContentLoaded', function() {
    const navLinks = document.querySelectorAll('nav a');
    navLinks.forEach(function(link) {
        link.addEventListener('click', function(e) {
            e.preventDefault();
            const targetId = this.getAttribute('href').substring(1);
            document.getElementById(targetId).scrollIntoView({ behavior: 'smooth' });
        });
    });
});
