Title

Add padding and borders to Ideas and Article components for improved design

Description

Issue: The Ideas and Article components lack sufficient padding and borders, making their design appear less polished. Adding padding and borders will enhance the visual appeal and readability of these components.

Screenshots:

Steps to Reproduce:

1. Go to the page where the Ideas component is rendered.
2. Observe the Article components and the overall layout.
3. Notice the lack of padding and borders.

Expected Behavior:

• Each Article component should have padding and a border to visually separate it from surrounding content.
• The Ideas component should have padding and borders applied to its container for a cleaner layout.
• Borders should be styled with a subtle color (e.g., border-gray-300).

Additional Information:

• If necessary, include any specific styling details or preferences.
• Provide links or references to the relevant code snippets or files where changes should be made.
