@MalloryHenriet is actually working on reworking the news card UI to have a fixed ratio of images, maximum text field and not overlapping button.

List of incoming features:

• Fixed images ratio
• Maximum text length
• Non overlapping button
• Smaller size of cards?

Add any other UI problems of news card in this PR.
