Problem statement: Create a navigation bar using reactJS & styled-component

Modules required:

npm install react-router-dom
npm install --save styled-components

Now create the components folder in src then go to the components folder and create a new folder name Navbar.In Navbar folder create two files index,js and NavbarElements.js.

Create one more folder in src name pages and in pages create files name about.js, annual.js, blogs.js, events.js, index.js, signup.js, team.js

Project Structure: The file structure in the project will look like this:

File pathe: Create index.js file in src/components/Navbar.
