• Add Code of conduct
• Add contributing.MD
• Add issue and pull request templates
• Add the folder structure instead of just files
• add actions for CI/CD
• Improvise the readme.md with all the necessary information the user/ contributor should know (I think you have used the basic template)
• Set up boards (Optional)

• Image and the place holder not aligned
• The attachment buttons are not active (Seems like an image)
• The tweet button should be right-aligned
• Alignment between the attachment buttons and tweet button is disturbed
  

• In the description, you added that this is developed using vanilla js
• The app doesn't add the data after clicking on a tweet
• Possible approaches :
  • Create a template for the tweet card
  • Every time the user types the tweet and click on tweet add it to the array (In javascript)
  • Re-render the site with all the components in the array

• According to my the ratio of the window should be 20%, 50%, 30% (Roughly)
• Check the below 2 images
  
  

Too many fonts used and font spacing and margins are not appropriate.

The border button is still there when you click on the button.

• No margin for home text.
  
• There is no border radius on actual twitter
  
• Use appropriate font weights and font families to make it similar

Line of the grid breaks,
tested on edge and firefox

The application isn't responsive in mobile mode. The navbar and main content window overlaps and the container doesn't even shrink to make it readable

• The icon set is not precise. (Seems like they are emoji)
• Proper padding and margin needed
• Again maintain the font-family & font-weight of the the buttons etc
  

• Too much margin in the clicking elements.
• The font weight of the username is very low
• The color of the username is too dull
