2021 UI Design Trends: From Glassmorphism to Dark Mode and Beyond

01 Glassmorphism

After the 2020 pandemic halted many industries, the Glassmorphism style emerged, emphasizing vertical Z‑axis space, background blur, and semi‑transparent layers that float in the interface. Its hallmark features are blurred transparency, layered depth, vibrant colors that highlight translucency, and subtle edge treatment that mimics glass. This effect makes web products appear richer, more three‑dimensional, and more attractive, especially for tech‑focused brands and hardware tools.

02 3D Elements

3D design is no longer novel, but it is becoming cooler and more prevalent across UI, websites, characters, and animation. Influenced by flat‑design minimalism, modern 3D illustrations are simpler yet impactful, and the trend is expected to continue throughout 2021.

03 Dark Mode

Dark mode has become a standard feature in many apps and mobile products, offering aesthetic appeal and reduced eye strain. It is expected to persist and grow in popularity throughout 2021.

04 Dark Mode Real Photos

Sometimes real photographs and objects provide stronger user engagement than 3D illustrations, delivering a more tangible and relatable experience.

05 Colorless UI

Colorless UI employs thin lines and black‑white (or subtle) illustrations, standing out among vibrant designs and offering a fresh minimalist aesthetic.

Conclusion

Design aesthetics constantly evolve; trends may fatigue quickly, prompting shifts every few years. Designers should explore the full potential of their products, using these trends to spark creativity and innovation.
