  React Essentials

• In this project, I have utilized the fundamental concepts of ReactJS such as Components, JSX, Props, and State. The aim of this project is to demonstrate how these concepts can be effectively used in building a functional application.

• The project showcases the dynamic rendering of content and images, with separate components like Header and CoreConcept being extracted from the main App component.

• Furthermore, to enhance the flexibility of my components, I have utilized Forwarding Props (or Proxy Props) to pass down props to child components without having to manually specify each one.

• I have also implemented two JSX Slots in my components to allow for dynamic content insertion.

• Additionally, I have experimented with setting component types dynamically.

• Lastly, I have leveraged hooks like useState and passed custom arguments to Event Functions to optimize the functionality of my components.

Overall, this project serves as a simple yet effective demonstration of the essential concepts of ReactJS. Feel free to explore the code and learn from it!

  SIGN IN FORM

Styling React Components

The main objective of this project is to enhance the visual appearance of "React applications" by applying various styling techniques.

➖ The web page is not functional as clicking "Create a new account" or "SIGN IN" does not do anything.
➖ However, entering invalid credentials will highlight the input fields with a red background color and border, indicating that conditional styles are present.

• Initially, I will utilize Vanilla CSS to style the application.
  

• After that, I will switch to CSS-in-JS styling using "Styled Components".
  

• Finally, in the last step of the project, I will modify the style of the application using Tailwind CSS.
