This pull request addresses issues with the UL elements being right aligned due to left padding being applied in custom.css .

Key changes:

• Removed padding: revert which was causing unnecessary left padding and misalignment of ul elements.
  Before:
  
  After:
  

Before(footer):

After(footer):

• Due to the removal of padding: revert the padding was set to 0 again for all the ul elements, because of which only the placement section was broken so added px-5 padding to the section which fixed all the things.
  Before(with padding:revert):
  

After(with px-5):

(remains the same)
