Definition and Usage
The :popover-open pseudo-class selects and
styles any element that is in a showing popover state.
By default, browsers displays popovers in the middle of the viewport.
The default styling of a popover in browsers is:
[popover] {
position: fixed;
inset: 0;
width:
fit-content;
height: fit-content;
margin: auto;
border: solid;
padding: 0.25em;
overflow: auto;
color: CanvasText;
background-color:
Canvas;
}
So, to override the default styles, you can use the :popover-open
pseudo-class.
