The design features a bold and modern design element that combines a geometric shape with a stylized letter. The main feature is a square with rounded corners, which is outlined in a thick black border. Inside this square, there is a white space that creates a striking contrast with the black border. Within this white space, the letter "D" is prominently displayed in a bold, sans-serif font. The "D" is also outlined in black, which adds to the overall symmetry and balance of the design. The simplicity and clean lines of the design give it a contemporary and stylish look.
