Description

[Please include a brief description of the changes or features added]
To resolve the bug with the Twitter icon, I implemented changes across three sections:

1. Added Font Awesome JavaScript link to index.html in the public folder within the frontend directory.
2. Inserted FontAwesome Twitter icon code into Footer.js located in the Src folder within the frontend directory.
3. Wrote CSS code in Footer.css within the style folder inside the Src directory.
   These adjustments successfully fixed the bug.
