Macro html 

macro_rules! html {
    ($($args:tt)+) => { ... };
}

Used to build a Dom and is a wrapper over DomBuilder<A>. By default the macro is internally typed to HtmlElement. Note if you want to generate SVG make sure to use the svg! macro.

html!("html_tag", { .dom_builder_methods })

// <div></div>
html!("div");

// <my-tag></my-tag>
html!("my-tag");

// <div>Hello world</div>
html!("div", {
    .text("Hello world")
});

// <div class="my-class">Hello world</div>
html!("div", {
     .text("Hello world")
     .class("my-class")
 });

It can be typed to any element that impl JsCast.

html!("html_tag" => internal_element_type , { .dom_builder_methods })

e.g. HtmlInputElement

// <input placeholder="type here">
html!("input" => HtmlInputElement, {
    .attr("placeholder", "type here")
});

Why would you want to know the type? Well once you start using some of the DomBuilder methods knowing the html element type allows you to call its associated methods:

html!("input" => HtmlInputElement, {
    .before_inserted(|input| {
        // .value() is a method on HtmlInputElement, but not on HtmlElement
        if input.value().is_empty() {
            input.set_value("Hello")
        }
    })
});
