Usage:
audio-recorder::part([selector]) {
/** css rules **/
}
Available selectors:
::part(button)
: styles the buttons except the volume buttons::part(volume-button)
: styles the volume buttons::part(slider)
: styles the volume slider::part(time)
: styles the elapsed and remaining time display
The buttons and slider are part of the material-webcomponents
library (https://dannymoerkerke.github.io/material-webcomponents/)
The Custom CSS properties exposed by these components can be used as part of the styling through ::part
.
For example, the material-slider
component exposes the properties --track-size
, --track-color
, --thumb-size
and
--thumb-color
.
These can be used in combination with ::part
to style the volume slider:
audio-recorder::part(slider) {
--track-color: #000000;
--track-size: 3px;
--thumb-color: #000000;
--thumb-size: 10px;
}
