In your `script.js` file, add JavaScript code to make your YouTube homepage interactive with features like a collapsible sidebar and theme toggling.

```javascript
const menuButtons = document.querySelectorAll(".menu-button");
const screenOverlay = document.querySelector(".main-layout .screen-overlay");
const themeButton = document.querySelector(".navbar .theme-button i");

// Toggle sidebar visibility when menu buttons are clicked
menuButtons.forEach(button => {
  button.addEventListener("click", () => {
    document.body.classList.toggle("sidebar-hidden");
  });
});

// Toggle sidebar visibility when screen overlay is clicked
screenOverlay.addEventListener("click", () => {
  document.body.classList.toggle("sidebar-hidden");
});

// Initialize dark mode based on localStorage
if (localStorage.getItem("darkMode") === "enabled") {
  document.body.classList.add("dark-mode");
  themeButton.classList.replace("uil-moon", "uil-sun");
} else {
  themeButton.classList.replace("uil-sun", "uil-moon");
}

// Toggle dark mode when theme button is clicked
themeButton.addEventListener("click", () => {
  const isDarkMode = document.body.classList.toggle("dark-mode");
  localStorage.setItem("darkMode", isDarkMode ? "enabled" : "disabled");
  themeButton.classList.toggle("uil-sun", isDarkMode);
  themeButton.classList.toggle("uil-moon", !isDarkMode);
});

// Show sidebar on large screens by default
if (window.innerWidth >= 768) {
  document.body.classList.remove("sidebar-hidden");
}
```
That’s it! If you’ve added the code correctly, you’re ready to see your YouTube clone project. Open the `index.html` file in your preferred browser to view the project in action.
