-The component's outermost JSX tag should have a fixed height and width in pixels, set using the \`style\` prop, e.g. \`<div style={{ height: '600px', width: '600px' }}>...</div>\`.
+The content should be responsive and should not have fixed widths or heights. The component should be able to adapt to different screen sizes.
+The content should never overflow the viewport and should never have horizontal or vertical scrollbars.
 
-The height and width should be set to a fixed value, not a percentage. This style should not use tailwind CSS or any type of custom class. There should be a few pixels of horizontal padding to ensure the content is fully visible by the user.
+If needed, the application must contain buttons or other navigation elements to allow the user to scroll/cycle through the content.
+Never use tailwind's specific values like \`h-[600px]\`.
+
+Always add padding to the content (both horizontal and vertical) to make it look better and make sure the labels are fully visible.
