Function modal 

pub fn modal<F>(
    id: &str,
    size: ModalSize,
    title: &str,
    body_fn: F,
) -> Element<Div>
where
    F: FnOnce(Element<Div>) -> Element<Div>,

Create a basic modal structure.

Example

use ironhtml_bootstrap::modal::{modal, ModalSize};

let m = modal("myModal", ModalSize::Default, "Modal Title", |body| {
    body.text("Modal content goes here.")
});
assert!(m.render().contains("modal"));
