Better file structure

Files could be arranged in a better way.

- example folders `./pages ./styles ./utils`
- In the `./pages` folder, we can add all the pages of the webpage and so on for other folders
- A readme file should be created which explains the code (Long term)

Review the repository tree against the proposed ./pages, ./styles, and ./utils folders. Decide how existing files would map into those folders, then document the resulting structure in a README. Done means the files are consistently organized and the README explains the layout.
