Vertical background template with a blue to beige gradient and subtle swirling patterns. It features two decorative rounded rectangular frames, one large at the top and one smaller at the bottom.

Create a rectangular background suitable for a classroom poster. The design should have a clear space at the top for a portrait photo and a space at the bottom for text (class name). Use a clean, modern, and respectful style with subtle patterns or gradients in soft colors (blue, green, or beige). The edges can be slightly rounded or have a decorative frame. No text or photos should be included, just the background template. See more
