UI/UX wireframes are low-fidelity sketches of the layout and functionality of a website or app. They are typically created in black and white, without any visual design elements, so that the focus can be on the structure and usability of the interface.

Wireframes are an essential tool for UI/UX designers, as they allow them to quickly and easily experiment with different ideas and get feedback from users and stakeholders early in the design process. This helps to ensure that the final product is both user-friendly and meets the needs of the business.
