Which style of art is best characterized by decorative elements and ornate detail?

The Rococo style is renowned for its ornate detail and decorative elements, making it the most fitting choice for this question. Emerging in the early 18th century, Rococo art is distinguished by its playful themes, lightness, and overall intricate designs, often featuring asymmetrical curves and whimsical motifs. This style contrasts with the more dramatic and grandiose aspects of Baroque art, which, although also detailed, focuses more on grandeur and emotional intensity, rather than the playful and ornamental features typical of Rococo.

While Romanticism emphasizes emotion and individualism, often with a focus on nature and dramatic subjects, and Impressionism captures the transient effects of light and color with less emphasis on detail, it is the Rococo style that specifically embodies the essence of decorative and ornate artistry. Hence, Rococo's unique characteristics of elegance and intricate decoration solidify its position as the best answer to the given question.
