I'm trying to make an extension for google which allow me to control the volume of every tab separately. I've read about how to make an extension and, by far, I know that I must learn some HTML, CSS, and JavaScript. However I don't know how to make it work.
I think I need to use APIs for this. I tried to use the chrome.audio API but it only works on Chrome OS. This is the manifest.json I'm using:
{
"name": "VolumeControl",
"version": "1.0",
"description": "Control the volume of every tab",
"permissions": [
"audio"
],
"manifest_version": 2,
"browser_action": {
"default_popup": "popup.html",
"default_title": "VolumeControl"
}
}
And this is the popup.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>VolumeControl</title>
</head>
<body>
<button>MUTE</button>
</body>
</html>
I know they are very simple and I haven't done much but I got stuck. Do you know what should I do and how to do it? If you know a different way to approach it, I'll be grateful to hear it.
Thanks in advance!
