[SOLVED] html react Problem B

Problem B
In this exercise you will practice developing a React application with components, props, state, and events. You will do this by converting an existing static website into a dynamic one.
Specifically, you will be implementing a dynamic website supporting pet adoption (like at an animal shelter). You can see what the website will look like by opening up the pets- mockup/index.html file in a browser: you will produce a dynamic, interactive version of this site using React.
Running the Program
Because this app is created with React (and scaffolded through Create React App), you will need to install dependencies and run a developer web server in order to transpile and view the application. You can run this server by using the command:
# from inside the `problem-b/` folder
cd path/to/problem-b
# install dependencies
npm install# only once
# run the server
npm start
You can then view the rendered page in a web browser. Remember to check the Developer console for any errors!
Exercise Instructions
To complete the exercise, edit the included src/App.js file and add in the required code. Note that you should NOT edit any of the other provided files (including index.js or index.html ).
(To make testing easier and more consistent, you will be defining all components for your App inside of the App.js module, as opposed to organizing them into separate modules).
Background: The first step to creating a React app is determining what components your page will need. One good way to do this is to start with a static version of the page (e.g., pure HTML/CSS) and try and break it up into different parts. These will often correspond to semantic sectioning or
