There are many common trends in user interface design, but some of the most popular ones include flat design, material design, and minimalism.
Flat design is a style of design that is characterized by its use of minimalistic elements and simplistic designs. This trend has become increasingly popular in recent years, as more and more people are looking for ways to simplify their lives.
Material design is a style of design that incorporates elements of both flat design and skeuomorphism. This trend combines the best of both worlds by providing users with an intuitive and easy-to-use interface that is still visually appealing.
Minimalism is a style of design that focuses on simplicity and functionality. This trend has become increasingly popular in recent years as people are looking for ways to declutter their lives.
