UI (User Interface)
Definition
The visual elements you interact with on a website or app – buttons, menus, forms, and layouts. Good UI looks beautiful and is intuitive to use.
What is UI?
UI stands for User Interface. It's everything you see and interact with on a website or app – the buttons you click, the forms you fill out, the navigation you use, and the overall visual design.
UI vs UX
These terms are often confused:
- UI (User Interface): How it looks and what you interact with
- UX (User Experience): How it feels and how easily you accomplish goals
A website can have beautiful UI but frustrating UX (looks great but confusing to use), or simple UI with excellent UX (plain looking but super easy to navigate).

Good UI Principles

Simplicity
Don't add elements that don't serve a purpose.
Why UI Matters for Business
