          <h2>Flexible Responders</h2>
          <p>
            Handler functions in Actix Web can return a wide range of objects that
            implement the <code>Responder</code> trait. This makes it a breeze
            to return consistent responses from your APIs.
          </p>

          <h2>Powerful Extractors</h2>
          <p>
            Actix Web comes with a powerful extractor system that extracts parts of the incoming
            HTTP request and passes it to your handler functions.
          </p>
          <p>
            A handler function can receive up to 12 arguments that implement the
            <code>FromRequest</code> trait, in any order, and Actix Web will automatically extract
            them from the request and provide them. It feels like magic!

          <p>
            Handling multipart/urlencoded form data is easy. Just define a structure that can be
            deserialized and Actix Web will handle the rest.

          <h2>Request Routing</h2>
          <p>
            The built-in Actix Web request router can be used with or without macros attached to
            handlers, and always provides flexible and composable methods of creating routing
            tables.
          </p>
          <p>
            Includes support for matching dynamic path segments, path prefix groups, and custom
