html-intro	Introduction	The procedural macro for generating HTML and SVG

The html! macro allows you to write HTML and SVG code declaratively. It is similar to JSX an extension to Javascript which allows you to write HTML-like code inside of Javascript.

Important notes

1. The html! macro only accepts one root html node (you can counteract this by using fragments or iterators)
2. An empty html! {} invocation is valid and will not render anything
3. Literals must always be quoted and wrapped in braces: html! { "Hello, World" }

:::note The html! macro can reach easily the default recursion limit of the compiler. It is advised to bump its value if you encounter compilation errors. Use an attribute like #![recursion_limit="1024"] in the crate root i.e. either `lib.rs` or `main.rs` to overcome the problem.

See the official documentation and this Stack Overflow question for details. :::
