    /// ## Definition and Usage
    /// - The <div> tag defines a division or a section in an HTML document.
    /// - The <div> tag is used as a container for HTML elements - which is then styled with CSS or manipulated with  JavaScript.
    /// - The <div> tag is easily styled by using the class or id attribute.
    /// - Any sort of content can be put inside the <div> tag!
    ///
    /// Note: By default, browsers always place a line break before and after the <div> element.
    ///
    /// ## Usage
    /// ```
    /// html!(<div> A header element </div>)
    /// rsx!(div { "A header element" })
    /// LazyNodes::new(|f| f.element(div, &[], &[], &[], None))
