//! Typed HTML support for Rust.
//!
//! HTML is not simple. There are many different nodes, attributes,
//! relationships, and types - and no compiler to help with any of that This
//! crate provides type-safe bindings to construct HTML elements natively in
//! Rust. So you don't have to remember whether `<ol>` takes a `<li>`, or whether
//! it's the other way around.
//!
//! # Examples
//!
//! We can create HTML structures one-by-one:
//! ```rust
//! use html::text_content::OrderedList;
//! let tree = OrderedList::builder()
//!     .list_item(|li| li.text("hello").class("pigeon"))
//!     .list_item(|li| li.text("world").class("pigeon"))
//!     .build();
//! let string = tree.to_string();
//! # assert_eq!(string, r#"<ol><li class="pigeon">hello</li><li class="pigeon">world</li></ol>"#);
//! ```
//! But we can also use Rust's native control flow structures such as loops to
//! iterate over items and create HTML:
//! ```rust
//! use html::text_content::OrderedList;
//! let mut ol = OrderedList::builder();
//! for name in ["hello", "world"] {
//!     ol.list_item(|li| li.text(name));
//! }
//! let tree = ol.build();
//! assert_eq!(tree.to_string(), r#"<ol><li>hello</li><li>world</li></ol>"#);
//! ```
