ملخص: Principles of Designing Professional and Attractive Website Interfaces

Learning Objectives

• Explain website design concepts: user experience (UX) and user interface (UI).
• List ideas for websites with good UX/UI design.
• Apply basic UX/UI principles in simple classroom activities.

User Experience (UX) Design

UX design is about how people use an application or website: can they easily find what they need, and do they feel comfortable using it? Example: finding a book in a library is easy when books are arranged in order and frustrating when they are thrown around randomly. If a site is easy to use, the user is satisfied and returns; if it is difficult, they may leave for good.

Basic UX principles

1. Ease of navigation: the user can quickly find what they want. A main menu with clear buttons such as Home, Books and Contacts is easy to navigate; a nested menu with many unclear sub-items is disorganized and confusing.
2. Clarity: information is presented so it is easy to understand, for example large, clear, easy-to-read text instead of small, ornate font.
3. Consistency: the same style is kept across the whole app or site. Buttons with the same shape and color everywhere feel familiar; buttons with different shapes and colors confuse the user.

User Interface (UI) Design

UI design is how a website, app or game looks: are the colors attractive, the buttons clear and the fonts readable? If buttons are too small to press, that is a UI design problem. A beautiful interface gives a good first impression, and an unattractive one is disliked.

Basic UI principles

1. Colors: the right colors affect the user's mood. A harmonious scheme such as blue and gray looks calm; bright clashing colors like red, yellow and purple are annoying and distracting.
2. Fonts: fonts must be legible and appropriate to the context. A simple, clear font is easy to read; a complex decorative font is difficult and unsuitable for practical applications.
3. Layout: organizing elements logically makes a site easy to use. A page divided into clear sections such as Home, News and Articles is organized; a page crammed with elements is cluttered and causes headaches.

UX versus UI

• UX: the design that makes using the site easy and convenient.
• UI: the design that makes the site beautiful and attractive.
• Example: in a restaurant, the decor and colors that attract you are the UI, while the quality of the food and service is the UX.

Good Examples

Google's site is simple and easy to use, so you find what you need quickly. YouTube has an attractive, easy-to-navigate design.
