Ctrl + mousewheel zoom not working #124513

The issue with the zoom functionality not working on your local development environment is likely related to JavaScript or CSS that interferes with the browser's default zoom behavior. Here are some steps you can take to diagnose and resolve this issue:1. Check JavaScript for Event ListenersLook for any event listeners that might be intercepting the window.addEventListener('wheel', (event) => {
if (event.ctrlKey) {
event.preventDefault();
}
}); 2. Inspect CSS for TransformationsEnsure that there are no CSS properties, such as html, body {
overflow: auto; /* Make sure overflow is not set to hidden */
transform: none; /* Avoid unwanted transformations */
} 3. Browser ExtensionsAlthough you mentioned that the issue does not occur with other websites, it's worth disabling all browser extensions to rule out any conflicts. 4. Check Developer ToolsUse the browser's developer tools to see if there are any errors or warnings in the console that could provide a clue. Also, look at the Event Listeners tab to see if any 5. Isolation TestingCreate a minimal HTML page with just the basic structure and gradually add your CSS and JavaScript to see at what point the zoom functionality breaks. <!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Zoom Test</title>
</head>
<body>
<h1>Test Zoom Functionality</h1>
<p>Use Ctrl + Mouse Wheel to test zooming.</p>
</body>
</html> 6. Viewport Meta TagEnsure that your viewport meta tag is correctly set and does not contain any attributes that could restrict zooming. <meta name="viewport" content="width=device-width, initial-scale=1.0"> 7. CSS Frameworks and LibrariesIf you are using any CSS frameworks (like Bootstrap) or JavaScript libraries, check their documentation and configuration to ensure they are not altering default zoom behavior. |

Hello,
I'm currently developing a website and I've encountered an issue where the zoom in/out functionality using the mouse wheel and Ctrl key is not working. This issue is only present on my local development environment and does not occur with other websites or codes. Here's what I've checked so far:
The website is still under construction and hasn't been deployed to a server yet. Could this be affecting the zoom functionality? I'm testing on the latest version of the browser and have tried different browsers as well.
Any insights or suggestions on what might be causing this issue and how to resolve it would be greatly appreciated.
Thank you!
