Correct the stylesheet filename to 'carbon-footprint.css'
The stylesheet link currently points to Carbo-footprint.css, which seems to be a typo. Updating it to carbon-footprint.css will ensure the styles load correctly.

Handle potential negative net waste values
If the recycled amount exceeds the waste amount, the net waste becomes negative, leading to an incorrect carbon footprint calculation. Adding a check to ensure netWaste is non-negative will improve accuracy.
Apply this diff to handle negative net waste values:
const netWaste = wasteAmount - recycledAmount;
+const adjustedNetWaste = Math.max(netWaste, 0);

Provide validation feedback within the page instead of using alerts
Using alert for validation messages can interrupt the user experience. Displaying messages within the page is less intrusive and provides a better UX.
Apply this diff to display validation messages on the page:
- alert("Please enter valid numbers.");
+ const resultDiv = document.getElementById('result');
+ resultDiv.innerHTML = "<strong>Please enter valid numbers.</strong>";
+ return;Make similar adjustments for other validation messages to maintain consistency.

Validate that input values are non-negative
Currently, users can enter negative values for waste amounts, which may not make sense in this context. Adding validation to ensure inputs are non-negative enhances data integrity.
Apply this diff to validate non-negative inputs:
if (isNaN(wasteAmount) || isNaN(recycledAmount)) {
alert("Please enter valid numbers.");
return;
}

Optimize scroll event listener for better performance
Attaching a function directly to the scroll event can impact performance due to the high frequency of scroll events. Consider throttling or debouncing the event handler.
Apply this diff to throttle the scroll event handler using requestAnimationFrame:
- window.addEventListener('scroll', () => {
+ let ticking = false;
+ window.addEventListener('scroll', () => {
+ if (!ticking) {
+ window.requestAnimationFrame(() => {
const windowHeight = window.innerHeight;
const documentHeight = document.documentElement.scrollHeight;
const scrollTop = window.pageYOffset || document.documentElement.scrollTop;
const scrollPercentage = (scrollTop / (documentHeight - windowHeight)) * 100;
progressBar.style.width = scrollPercentage + '%';
+ ticking = false;
+ });
+ ticking = true;
+ }
});This approach improves performance by reducing the number of times the function executes during scrolling.

Duplicate .social-media class definitions
The .social-media class is defined twice with different styles at lines 200-205 and 286-288. This can lead to confusion and unexpected styling issues.
To resolve this, consider merging the styles or renaming one of the classes to prevent conflicts.
/* Combine the styles or rename one of the classes */
.social-media {

Conflicting styles for .social-media a
The styles for .social-media a are defined twice with differing properties at lines 206-215 and 290-293. This might result in inconsistent styling for social media links.
Consider unifying these styles or using more specific class names to avoid conflicts.

Merge media queries for better maintainability
There are two separate @media (max-width: 768px) queries with overlapping styles at lines 114-122 and 222-249. Merging them can simplify the CSS and make it easier to maintain.
Combine the media queries into one:
@media (max-width: 768px) {
.nav-menu {
display: none; /* Hide nav menu on smaller screens */
}
#menu-toggle {
display: block; /* Show menu toggle button */
}
+ header {

Missing box-sizing on containers
Adding box-sizing: border-box; to the .container class ensures padding and border are included in the total width and height, preventing layout issues.
Apply this diff to add box-sizing:
main .container {
width: 100%; /* Ensures the container takes full width but stays within max-width */
max-width: 600px; /* Keeps the layout consistent */
background-color: #FFDDD2; /* Matches the container's background */
border: 1px solid #006D77;
border-radius: 10px;
padding: 20px;
box-shadow: 0 4px 15px rgba(0, 0, 0, 0.1);
