Is there a way to mute the audio of an iframe using jQuery or CSS?
This is the iframe I need to mute
You can only mute HTML5 audio
and video
elements.
An iframe does not have an audio API, so you can't mute anything using JS on that element. If you can find a workaround to the restrictions from the same-origin policy, you maybe can select the real audio or video element inside the iframe and mute that.
There is a W3C recommendation for “aural style sheets”, but I don't know how the browser support for that look like. Using those properties you probably could mute any HTML element:
iframe {
volume: silent;
}
