Programming: Responsive Web

To create a responsive webpage with a static titlebar and a side menu that is hidden when the screen is too small, you can use HTML, CSS, and JavaScript. Here's an example:

Create an HTML file (e.g., index.html):

html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <link rel="stylesheet" href="styles.css">
  <script src="script.js" defer></script>
  <title>Responsive Webpage</title>
</head>
<body>
  <header>
    <h1>Title Bar</h1>
    <button id="menu-btn">☰</button>
  </header>
  <nav id="side-menu">
    <ul>
      <li><a href="#">Home</a></li>
      <li><a href="#">About</a></li>
      <li><a href="#">Contact</a></li>
    </ul>
  </nav>
  <main>
    <h2>Welcome to the Responsive Webpage</h2>
    <p>This is an example of a responsive webpage with a static title bar and a side menu that is hidden when the screen is too small.</p>
  </main>
</body>
</html>

Create a CSS file (e.g., styles.css):

css
* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

body {
  font-family: Arial, sans-serif;
}

header {
  background-color: #333;
  display: flex;
  justify-content: space-between;
  padding: 1rem;
  position: fixed;
  width: 100%;
  z-index: 1;
}

header h1 {
  color: white;
  margin: 0;
}

button {
  background-color: transparent;
  border: none;
  color: white;
  font-size: 1.5rem;
  cursor: pointer;
}

#side-menu {
  background-color: #f0f0f0;
  height: 100%;
  left: -200px;
  padding: 1rem;
  position: fixed;
  top: 0;
  transition: all 0.3s;
  width: 200px;
}

#side-menu ul {
  list-style-type: none;
}

#side-menu li {
  margin-bottom: 1rem;
}

#side-menu a {
  color: #333;
  text-decoration: none;
}

main {
  margin-left: 1rem;
  margin-top: 70px;
  padding: 1rem;
}

@media (min-width: 768px) {
  #menu-btn {
    display: none;
  }
  
  #side-menu {
    left: 0;
  }
}

Create a JavaScript file (e.g., script.js):

javascript
document.getElementById('menu-btn').addEventListener('click', function() {
  const sideMenu = document.getElementById('side-menu');
  const leftValue = sideMenu.style.left === '0px' ? '-200px' : '0px';
  sideMenu.style.left = leftValue;
});

This code will create a responsive webpage with a static title bar and a side menu that is hidden when the screen width is smaller than 768 pixels. When the screen is too small, a menu button will appear in the title bar, and clicking on it will show or hide the side menu.
