Ana 正在创建轮播广告。她应该如何设计？

For carousel ads, visual continuity is crucial because it guides the viewer through a narrative or a series of related products/features. Consistent branding, color schemes, and design elements across all images create a cohesive experience, making the ad feel like a single, flowing story rather than a collection of disparate images. This consistency helps maintain viewer engagement and reinforces the brand message. If all images have a different look and feel, the ad can appear disjointed and confusing, potentially causing the viewer to lose interest or miss the intended message.
