Create a vibrant bubble-themed background featuring an array of colorful bubbles in various sizes, gently floating across a soft gradient backdrop that transitions from pastel blue at the top to light pink at the bottom. Include subtle highlights and reflections on the bubbles to give them a three-dimensional look, and incorporate delicate sparkles or glints of light to enhance the magical feel. The overall atmosphere should be whimsical and joyful, perfect for a cheerful wallpaper design.
