In the world of web development, creating engaging and interactive user interfaces is crucial. One way to captivate your visitors’ attention is by adding dynamic elements to your website. In this article, we’ll walk you through how to create a captivating dynamic typing animation using React hooks and the Bootstrap framework. We’ll break down the code step by step and guide you on where to copy and paste each section.

## 1. Setting Up the React App

Before we dive into the code, make sure you have a React project set up. If you haven’t already, you can create a new React app using the following command:

`npx create-react-app dynamic-typing-animation`
install some packages:

`npm install react-bootstrap bootstrap react-bootstrap-icons react-on-screen`
In your app.js file, you'll import necessary dependencies and the Banner component. This component will serve as the main content of your application. Copy and paste the following code into your app.js file:

```

// app.js
import logo from "./logo.svg";
import "./App.css";
import "bootstrap/dist/css/bootstrap.min.css";
import { Banner } from "./components/Banner";

function App() {
  return (
    <div className="App">
      <Banner />
    </div>
  );
}

export default App;
```
Next, you’ll implement the dynamic typing animation in the Banner component. This component uses hooks to manage state and timing for the animation.

```

// banner.js
import { useState, useEffect } from "react";
import { Container, Row, Col } from "react-bootstrap";
import { ArrowRightCircle } from "react-bootstrap-icons";
import TrackVisibility from "react-on-screen";

export const Banner = () => {
  const [loopNum, setLoopNum] = useState(0);
  const [isDeleting, setIsDeleting] = useState(false);
  const [text, setText] = useState("");
  const [delta, setDelta] = useState(300 - Math.random() * 100);
  const [index, setIndex] = useState(1);
  const toRotate = ["Web Developer", "Web Designer", "UI/UX Designer"];
  const period = 2000;

  useEffect(() => {
    let ticker = setInterval(() => {
      tick();
    }, delta);

    return () => {
      clearInterval(ticker);
    };
  }, [text]);

  const tick = () => {
    let i = loopNum % toRotate.length;
    let fullText = toRotate[i];
    let updatedText = isDeleting
      ? fullText.substring(0, text.length - 1)
      : fullText.substring(0, text.length + 1);

    setText(updatedText);

    if (isDeleting) {
      setDelta((prevDelta) => prevDelta / 2);
    }

    if (!isDeleting && updatedText === fullText) {
      setIsDeleting(true);
      setIndex((prevIndex) => prevIndex - 1);
      setDelta(period);
    } else if (isDeleting && updatedText === "") {
      setIsDeleting(false);
      setLoopNum(loopNum + 1);
      setIndex(1);
      setDelta(500);
    } else {
      setIndex((prevIndex) => prevIndex + 1);
    }
  };

  return (
    <section className="banner" id="home">
      <Container>
        <Row className="aligh-items-center">
          <Col xs={12} md={6} xl={7}>
            <TrackVisibility>
              {({ isVisible }) => (
                <div
                  className={
                    isVisible ? "animate__animated animate__fadeIn" : ""
                  }
                >
                  <span className="tagline">Welcome to my Portfolio</span>
                  <h1>
                    {`Hi! I'm Lorem`}{" "}
                    <span
                      className="txt-rotate"
                      dataPeriod="1000"
                      data-rotate='[ "Web dev", "Web master", "UI/UX programmer" ]'
                    >
                      <span className="wrap">{text}</span>
                    </span>
                  </h1>
                  <p>
                    Lorem Ipsum is simply dummy text of the printing and
                    typesetting industry. Lorem Ipsum has been the industry's
                    standard dummy text ever since the 1500s, when an unknown
                    printer took a galley of type and scrambled it to make a
                    type specimen book.
                  </p>
                  <button>
                    Let’s Connect <ArrowRightCircle size={25} />
                  </button>
                </div>
              )}
            </TrackVisibility>
          </Col>
          <Col xs={12} md={6} xl={5}>
            <TrackVisibility>
              {({ isVisible }) => (
                <div
                  className={
                    isVisible ? "animate__animated animate__zoomIn" : ""
                  }
                >
                  <img
                    src={"https://i.imgur.com/DC4LkuS.png"}
                    alt="Header Img"
                    style={{ width: 500 }}
                  />
                </div>
              )}
            </TrackVisibility>
          </Col>
        </Row>
      </Container>
    </section>
  );
};
```

## 4. Copy and Paste App.css

Finally, add the necessary CSS to style your dynamic typing animation. Copy and paste the following CSS code into your App.css file:

```

/* App.css */
/************ Default Css ************/
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

html {
  scroll-behavior: smooth;
  scroll-padding-top: 75px;
}

body {
  font-weight: 400;
  overflow-x: hidden;
  position: relative;
  background-color: #121212 !important;
  color: #fff !important;
  font-family: "Centra", sans-serif !important;
}

button {
  border: 0;
  background-color: transparent;
}
```

## 5. Styling Your Dynamic Typing Animation

  margin-left: 25px;
}
.banner img {
  animation: updown 3s linear infinite;
}
@keyframes updown {
  0% {
    transform: translateY(-20px);
  }
  50% {
    transform: translateY(20px);
  }
  100% {
    transform: translateY(-20px);
  }
}
.txt-rotate > .wrap {
  border-right: 0.08em solid #666;
}
```

## 6. Run Your React App

With all the code in place, you’re ready to see your dynamic typing animation in action. Open your terminal, navigate to your project directory, and run:

`npm start`
This will start your development server, and you can view the dynamic typing animation by opening your browser and visiting `http://localhost:3000.`

## Congratulations!
