if UI is the joke (if you have to explain it, it's not that good), wireframes are the 100-page stand-up routine draft. You don't want anyone to see it, but your design depends on it. Wireframes are low-fidelity blueprints of a landing page or app screen. They deal with layouting, page structure, how information is displayed, functionalities and user flow. They`re less concerned with things such as styling or graphics, that's why most wireframes look like black and white sketches drawn by a 5-year old.
“I've seen the wireframes on your desk. Good work, Olivia.” “What? That's my daughter`s kindergarten art project.”
