You can do actual html. This is Leptos, a Solidjs like rust library:

    #[component]
    fn App() -> impl IntoView {
        let (count, set_count) = signal(0);
        view! {
            <button
                on:click=move |_| set_count.set(3) >
                "Click me”</button>
            <p>{move || count.get() * 2}</p>
        }
    }
