//! # Yew Alert - Documentation
//!
//! Welcome to the official Yew Alert library documentation. This library
//! provides a flexible and customizable alert component for your Yew applications.
//!
//! ## Usage
//!
//! To use the Yew Alert library, add the following dependency to your `Cargo.toml` file:
//!
//! ```sh
//! cargo add yew-alert
//! ```
//!
//! To integrate the library into your Yew application, you can use the `Alert` component.
//! Here's a simple example of how to use it:
//!
//! ```rust,no_run
//! use yew::prelude::*;
//! use yew_alert::Alert;
//!
//! // Your Yew component structure here...
//!
//! #[function_component]
//! pub fn MyComponent() -> Html {
//!     // Your component logic here...
//!     let show_alert = use_state(|| true);
//!
//!     html! {
//!         <div>
//!             <button onclick=/* Your callback function here to trigger the alert */>{"Show Alert"}</button>
//!             <Alert
//!                 message="This is a sample alert message."
//!                 show_alert={show_alert} // Use your state or logic to control visibility
//!                 on_confirm=Callback::from(/* Your confirm callback function here */)
//!                 on_cancel=Callback::from(/* Your cancel callback function here */)
//!             />
//!         </div>
//!     }
//! }
//! ```
//!
//! For more detailed information, check the [examples] provided in the library.
//!
//! [examples]: https://github.com/next-rs/yew-alert/examples/tailwind
//!
//! ## Configuration
//!
//! Yew Alert allows you to customize various aspects of the alert component through the
//! `AlertProps` structure. You can adjust properties such as message content, button text,
//! styling, and more. Refer to the `AlertProps` documentation for detailed configuration options.
//!
//! ```rust,no_run
//! use yew_alert::{AlertProps, Alert};
//!
//! let alert_props = AlertProps {
//!     message: "Custom alert message",
//!     // Add other properties as needed...
//!     // ...
//! };
//!
//! let alert_component = html! {
//!     <Alert ..alert_props />
//! };
//! ```
//!
//! ## Contribution and Support
//!
//! If you encounter any issues or have suggestions for improvements, feel free to contribute
//! to the [GitHub repository](https://github.com/next-rs/yew-alert). We appreciate your feedback
//! and involvement in making Yew Alert better!
//!
//! ## Acknowledgments
//!
//! Special thanks to the Yew community and contributors for such an amazing framework.
