@SantiagoPerez @Robert_Petitto This is an interesting discussion. I read about this a while ago and you can use the audio tag in CSS to style the audio, but beware of how it looks in different browsers, should test first to be sure.
Here’s the source code for all elements involved:
Here’s a sample.
<pre><span><style>
audio::-webkit-media-controls-enclosure {
width: 100%;
max-width: 800px;
height: 30px;
flex-shrink: 0;
bottom: 0;
text-indent: 0;
padding: 10px 5px 5px 0px;
box-sizing: border-box;
background-color: #90EE90;
}
