I'm trying to code a mute button that corresponds to a volume slider for a project I'm working on. Currently, I'm trying to make the mute & unmute buttons have different images but it isn't working. Can anyone tell me why?
Here is my code:

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.slidecontainer {
height: 5px;
width: -5px;
}

.slider {
-webkit-appearance: none;
width: 100%;
height: 100%;
max-width: 200px;
background: #d3d3d3;
outline: none;
opacity: 1;
-webkit-transition: .2s;
transition: opacity .2s;
transform: rotate(90deg);
}

.slider::-webkit-slider-thumb {
-webkit-appearance: none;
appearance: none;
width: 5px;
height: 20px;
background: #04AA6D;
cursor: pointer;
}

.slider::-moz-range-thumb {
width: 25px;
height: 25px;
background: #04AA6D;
cursor: pointer;
}

#imageButton {
width: 90px; /* Adjust the width as desired */
height: 70px; /* Adjust the height as desired */
border: 0px solid #000; /* Adjust the border width and color as desired */
border-radius: 0px; /* Adjust the border radius as desired */
display: inline-block; /* Ensure the button retains its dimensions */
overflow: hidden; /* Ensures the image fits within the button */
position: relative; /* Position the icons */
cursor: pointer; /* Add cursor pointer to indicate clickability */
}

#imageButton img {
width: 100%;
height: 100%;
object-fit: cover; /* Preserve aspect ratio of the image within the button */
}

#muteIcon {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
display: block; /* Initially visible */
}

#unmuteIcon {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
display: none; /* Initially hidden */
}
</style>
</head>
<body>

<div class="slidecontainer">
<input type="range" min="0" max="1" step="0.05" value="0.5" class="slider" id="myRange">
</div>

<audio id="myAudio" src="path/to/audio.mp3" type="audio/mpeg"></audio>

<button id="imageButton" type="button" onclick="toggleMute()">

<img id="unmuteIcon" src="C:\Users\PCNAMEPLACEHOLDER\Downloads\image.jpg" alt="Unmute Icon">
</button>

<script>
var slider = document.getElementById("myRange");
var audio = document.getElementById("myAudio");
var imageButton = document.getElementById("imageButton");
var muteIcon = document.getElementById("muteIcon");
var unmuteIcon = document.getElementById("unmuteIcon");
var isMuted = false;

// Function to toggle mute/unmute and update icons
function toggleMute()

In your code, the image paths for the mute and unmute icons are set to local paths on your computer (C:\Users\PCNAMEPLACEHOLDER\Downloads\ERMEGBkU0AAr_L9.jpg and C:\Users\PCNAMEPLACEHOLDER\Downloads\image.jpg). When running the code in a web browser, the browser cannot access files from your local file system due to security restrictions. Therefore, you need to use relative or absolute URLs to reference the images.

Here's an example of how you can update the image paths to use relative URLs:

htmlCopy code
<button id="imageButton" type="button" onclick="toggleMute()">
<img id="muteIcon" src="ERMEGBkU0AAr_L9.jpg" alt="Mute Icon">
<img id="unmuteIcon" src="image.jpg" alt="Unmute Icon">
</button>

Make sure that the images ERMEGBkU0AAr_L9.jpg and image.jpg are placed in the same directory as your HTML file or provide the correct relative path to the images if they are in a different directory.

By using relative URLs, the images will be accessible to the browser, and you should be able to see the mute and unmute icons properly when the buttons are clicked.

Additionally, in the provided code, there seems to be a missing implementation for the toggleMute() function. You can complete the function to toggle the audio mute state and update the mute/unmute icons accordingly. Here's an example of how you can update the JavaScript code:

javascriptCopy code
// Function to toggle mute/unmute and update icons
function toggleMute() {
if (isMuted) {
audio.muted = false; // Unmute the audio
muteIcon.style.display = "block";
unmuteIcon.style.display = "none";
} else {
audio.muted = true; // Mute the audio
muteIcon.style.display = "none";
unmuteIcon.style.display = "block";
}

// Toggle the mute state
isMuted = !isMuted;
}

Now, when you click the mute/unmute button, it will toggle the mute state of the audio element and update the mute/unmute icons accordingly.

THANK YOU SO MUCH! One question: what triggers the audio starting, is it on load or is it when clicking something?

If you want the audio to start playing automatically when the page loads, you can add the autoplay attribute to the <audio> element like this:

<audio id="myAudio" src="path/to/audio.mp3" type="audio/mpeg" autoplay></audio>

By adding the autoplay attribute, the audio will start playing automatically when the page loads.

If you want to start the audio only when the user clicks the mute/unmute button, you can remove the autoplay attribute from the <audio> element and use the provided toggleMute() function to toggle the audio play/pause state.

you can add the autoplay attribute to the <audio> element

If you want to use the autoplay attribute, it's a good programming practice to set the volume attribute to 50% or less, because the user won't be surprised by the loud music when he enters your site.

HTML:
<audio autoplay volume="0.5">
    <source src="path_to_audio_file.mp3" type="audio/mpeg">
    <source src="path_to_audio_file.ogg" type="audio/ogg">
    Your browser does not support the audio element in either MP3 or Ogg format.
</audio>

As a curiosity, check out the use of the svg version of the icons, which are available for free on the bootstrap website.

Bootstrap Icons

Free, high quality, open source icon library with over 1,800 icons. Include them anyway you like—SVGs, SVG sprite, or web fonts. Use them with or without Bootstrap in any project.

  • Icons volume set
  • Volume off fill
    HTML:
    <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" fill="currentColor" viewBox="0 0 16 16">
      <path d="M10.717 3.55A.5.5 0 0 1 11 4v8a.5.5 0 0 1-.812.39L7.825 10.5H5.5A.5.5 0 0 1 5 10V6a.5.5 0 0 1 .5-.5h2.325l2.363-1.89a.5.5 0 0 1 .529-.06z"/>
    </svg>
