Mastering React

1. Introduction to React Fundamentals

Gain an understanding of the core principles of React. You'll learn about JSX (JavaScript XML), building reusable UI components, and rendering elements. Additionally, you'll explore the importance of data collection and conditional rendering in React applications. By the end of this section, you'll have a solid foundation of React's essential concepts, setting you up for success in the more advanced topics covered in the following sections.

3. React Hooks and Context

Powerful features in modern React development. Hooks revolutionize how we write functional components, providing a concise and intuitive way to manage state and perform side effects. Conversely, Context allows us to share data through the component tree without prop drilling. Combining hooks and Context enables efficient state management and simplified data sharing in React applications.

Challenge: Inline Styles

We will practice adding inline styles to a React component. Follow the steps below to complete the challenge:

Create a new React component called StyledBox.
Inside the StyledBox component, render a <div> element.
Add the following inline styles to the <div> element:
- Set the background color to "lightblue";
- Set the width to "300px";
- Set the padding to "10px";
- Set the border radius to "10px";
- Set the text alignment to "center";
- Set the font size to "24px";
- Set the font weight to "bold".
Add some text content inside the <div> element, such as Five Finger Death Punch.

Inline styles are added using the style attribute, and the value for this attribute should be an object.
When using inline styles, values that are not plain numbers (such as strings, units, or colors) should be enclosed in quotes "...". For example, margin: "30px" indicates that the margin property has a value of 30px.
