Custom Pseudo-Classes
These are some s&box-specific pseudo-classes which are useful for applying transitions when an element is created or deleted.
:introis removed when the element is created, things will transition away from this:outrois added when Panel.Delete() is called. The Panel waits for all transitions to finish before actually deleting itself.
MyPanel {
transition: all 2s ease-out;
transform: scale( 1 );
// When the element is created make it expand from nothing.
&:intro {
transform: scale( 0 );
}
// When the element is deleted make it double in size before being deleted.
&:outro {
transform: scale( 2 );
}
}
