Hello,

The audio player will look different depending the user browsing context.

You can customizing it thanks to the AUDIO tag though. Ex:

.page audio { background: var(--theme-accent-color); }

In a more reliable way (that would work for all major browsers), only with JS.

Ah alr, thanks!

Knowing that color is a possibility, is a title able to be added somehow?

You can use normal captions for files:
