Wireframes are an important part of any UI design project and come in three varieties: low-fidelity, mid-fidelity, and high-fidelity. Low-fidelity wireframes have basic shapes, placeholders, and labels for different interface elements, while mid and high-fidelity wireframes are more detailed, offering a visual representation of how the finished product will look. These wireframes are used to communicate the design intent to stakeholders and developers, and to ensure that the design meets the user’s needs. They are also used to test the usability of the design and to identify any potential issues before the design is finalized.
