UI Breaks on Some Pages Due to Incomplete Responsive Design

[Evcat6]

How it currently looks:
On smaller screens (e.g., Surface Pro 7), the YouTube player breaks the UI significantly due to missing or insufficient responsive styles. On even smaller screens, the issue becomes worse.

How it should look (in my opinion):

This problem is present on following pages:

• AI-Warp
• Caching
• Composer
• DB
• Stackables
