html::img(|a: &mut AC| a.set("href", "logo.png"))
svg::circle((), ())

Attributes

// None

// Class shortcut (first arg)
html::div("container", "text")
html::div(("btn", "primary"), "text")

// Conditional classes
html::div(("btn", is_active.then_some("active")), ())

// Inline styles
html::div(|a: &mut AC| {
    a.set("style", style(|s: &mut SC| {
        s.set("color", "red")?;
        s.set("font-size", "1rem")
    }))
}, ())

// Closure
html::div(|a: &mut AC| {
    a.set("id", "main")?;
    a.set("data-val", "42")?;
    a.set("disabled", true)
}, ())

Text

html::div((), "escaped <text>")       // &lt;text&gt;
html::div((), SafeStr("<raw>"))       // <raw> (unescaped)
html::div((), format_args!("{}", n))  // formatted, escaped

// Also works with children context `CC`
html::div((), |c: &mut CC| {
    c.add("text")
})
