[Yashop181]

I have fixed the issue with the Twitter logo missing error and my PR is #32.

Changes made:
• The src attribute for the Twitter image has been changed from twitter.png to twitter-squared.png.
Improvements:

1. Consistency in HTML Structure: Ensure that each
   has a closing tag and that the structure is consistent.
2. Use of Alt Attributes: Adding alt attributes to tags improves accessibility.
3. Link Targets: If these links are meant to be placeholders, ensure they are clearly marked or consider using actual URLs if known.
4. Optimization: If the image URLs are expected to change often, consider using a central configuration or constant to manage them.
   Improved Code:
   html
   Copy code

Key Points: • Ensure consistent HTML structure. • Use alt attributes for accessibility. • Placeholder links should be marked clearly or updated with actual URLs. • Consider managing frequently changing resources centrally.
