Much of element styling is now handled by an external engine.
How do I make an element hover.
There's a hover style.
Hoverable needs to wrap another element. That element can be styled.
```rs
struct Hoverable<E: Element> {
}
impl<V> Element<V> for Hoverable {
}
```
```rs
#[derive(Styled, Interactive)]
pub struct Div {
declared_style: StyleRefinement,
interactions: Interactions
}
pub trait Styled {
fn declared_style(&mut self) -> &mut StyleRefinement;
fn compute_style(&mut self) -> Style {
Style::default().refine(self.declared_style())
}
// All the tailwind classes, modifying self.declared_style()
}
impl Style {
pub fn paint_background<V>(layout: Layout, cx: &mut PaintContext<V>);
pub fn paint_foreground<V>(layout: Layout, cx: &mut PaintContext<V>);
}
pub trait Interactive<V> {
fn interactions(&mut self) -> &mut Interactions<V>;
fn on_click(self, )
}
struct Interactions<V> {
click: SmallVec<[<Rc<dyn Fn(&mut V, &dyn Any, )>; 1]>,
}
```
```rs
trait Stylable {
type Style;
fn with_style(self, style: Self::Style) -> Self;
}
