Crafted to be your ultimate roadmap in the journey of UI design. Whether you are a seasoned designer looking to refresh your approach or a novice eager to learn the ropes, these rules are tailored to help you create interfaces that are not just visually appealing but also intuitively functional. To navigate this complex terrain, I have compiled 58 rules across eight categories, collectively forming the “Elegance Formula” for user interface design.

🫀 Empathy: There is no universal concept of beauty; only when you truly understand your target audience can you create a design that is appealing to them.

🖼️ Layout: The layout is the canvas of your interface; it should guide the user’s eye effortlessly, creating a seamless flow that intuitively connects each element.

🎟 Essentialism: Embrace simplicity; every element in your design should serve a purpose, as clutter can obscure the message and hinder the user experience.

🧭 Guidance: Design should not just please the eye but also lead the user, providing clear pathways and cues for what they should do next.

💎 Aesthetics: Aesthetics go beyond mere appearance; they encapsulate the feel of the design, creating an environment that resonates emotionally with the user.

🛸 Novelty: Innovative designs capture attention, but the true art lies in balancing novelty with familiarity, ensuring users feel intrigued yet comfortable.

🎛 Consistency: Consistency in design breeds familiarity; it ensures the user feels at home across various parts of your interface, building trust and ease of use.

🕹 Engagement: An engaging design is like a good conversation; it keeps the user interested, responds to their actions, and encourages them to come back for more.

Cultural and societal influences play a crucial role in shaping preferences and perceptions

1. Consider Cultural and Societal Influences: Factor in the diverse cultural and societal backgrounds of your audience to ensure your design resonates broadly and respectfully.

2. Understand Industry and Context of Use: Tailor your design to align with the specific industry norms and the practical context in which your interface will be used.

3. Embrace User Demographics: Embrace the diversity in user demographics, incorporating insights about age, gender, profession, and other factors to craft a more tailored and effective interface.

4. Adapt to Your Audience’s Tech-Savviness: Customize your interface to suit the specific tech-savviness level of your target audience

The Nielsen Norman Group’s research across different demographics — highlighting the unique online behaviors and expectations of young adults, the evolving digital literacy and specific usability needs of seniors, and the distinct and varying design requirements for children — emphasizes the critical importance of empathetic and user-centric design in user interface development to cater effectively to each group’s unique characteristics and preferences.

A well-planned layout is not just about placing elements on a screen; it’s about creating a visual symphony that directs, delights, and engages users

5. Embrace Negative Space: Use negative space wisely to create a clean, uncluttered interface that highlights the most important elements and improves readability.

6. Use the Golden Ratio or Rule of Thirds: Incorporate the Golden Ratio or the Rule of Thirds in your design to achieve natural balance and aesthetically pleasing proportions.

7. Establish a Clear Hierarchy with Size, Color, and Spacing: Utilize variations in size, color, and spacing to create a visual hierarchy that guides the user’s eye to the most significant information first.

8. Utilize Grid Systems: Implement grid systems to bring structure and consistency to your layout, ensuring a cohesive and harmonious arrangement of elements.

9. Create a Clear Focal Point: Designate a clear focal point in your layout to capture immediate attention and orient the user’s interaction with your content.

10. Create Rhythm to Direct Attention: Employ rhythmic design elements, such as repeated patterns or structured layouts, to create a visual flow that intuitively directs the user’s attention through the interface.

In addition, consider utilizing F and Z-pattern layouts to match users’ natural scanning habits. Employ the F-pattern in text-dense interfaces, strategically placing crucial information at the top and left.

Simplicity is ultimate sophistication

It’s about stripping away the non-essential elements and focusing on what truly matters to the user.

11. Achieve Simplicity Through Thoughtful Reduction: Prioritize content and features, removing anything non-essential. Focus on the core functionalities to create a streamlined and more user-friendly interface.

12. Organization Helps the System of Many Look Fewer: Use clear categorization and grouping of elements. Implement drop-down menus or tabs to organize content, making the interface less cluttered and more navigable.

13. Don’t Make Users Think: Ensure that navigation and task flows are logical and predictable. Use common UI elements and place them where users expect them to be, reducing cognitive load.

14. Good Design is as Little Design as Possible: Adopt a minimalist approach, using only elements that are necessary for functionality. Avoid excessive use of colors, fonts, and graphics to maintain a clean and focused interface.

15. Break Up Huge Tasks into Smaller Steps: Design complex processes, like forms or multi-step tasks, into smaller segments. Use progress bars or breadcrumbs to visually indicate the user’s progress and what remains.

16. Savings in Time Feel Like Simplicity: Optimize load times and streamline processes to make interactions quicker. Use smart defaults, autocomplete features, and predictive text to speed up user input and decision-making.

It’s not just about leading the user from point A to point B; it’s about creating a journey that feels natural, effortless, and engaging

The art of designing a user interface involves guiding the user through a digital landscape with intuition and ease.

17. Craft Engaging User Onboarding: Start by designing an engaging onboarding process that educates users about your product from the first interaction. Effective onboarding lays the foundation for the user’s entire experience with your interface.

18. Ensure an Intuitive Flow: Develop your interface with a logical, step-by-step flow that feels natural and requires minimal effort for users to navigate, enhancing their overall experience.

19. Offer Contextual Hints and Tips: Implement contextual assistance such as tooltips, pop-ups, or inline instructions that appear when users need them, aiding in their understanding and use of the interface.

20. Implement Progressive Disclosure: Strategically reveal information to users, showing only what’s necessary at each step. This approach helps maintain a clean interface and focuses the user’s attention on immediate tasks.

21. Design to Encourage User Actions: Use clear design elements like buttons, icons, and calls to action to guide users towards desired interactions, ensuring these elements are prominent and easily accessible.

22. Provide Feedback for User Actions: Create a system that offers immediate visual or auditory feedback for user actions, acknowledging their interactions and guiding them to the next step in the interface.

Masterfully applied typography helps you stand out, enhance readability and aesthetic appeal

23. Establish Typography Hierarchy: Create a clear hierarchy using different font sizes, weights, and styles to guide the user’s attention to the most important content first.

24. Prioritize Readability: Choose fonts that are easy to read on various devices and screen sizes. Legibility should be a top priority, especially for body text.

25. Reflect Brand Mood: Select fonts that align with your brand’s personality. Whether it’s professional, playful, or elegant, typography should reinforce the brand’s tone.

26. Pair Fonts Wisely: When combining multiple fonts, ensure they complement each other.

27. Limit Font and Style Variations: Too many font types or styles can create a cluttered and confusing interface. Stick to a limited set to maintain a clean and cohesive look.

28. Adjust Line Spacing, Kerning, and Line Height: Proper spacing between letters (kerning), words, and lines improves readability and text flow. Experiment with different settings to find the most visually appealing and readable format.

The right color choices can make a significant difference in how users perceive and interact with a product

29. Contrast is Key: Ensure sufficient contrast between text and background to enhance readability and accessibility.

30. Create and Use a Consistent Color Palette: Develop a consistent color palette that reflects your brand identity and use it consistently across your interface to maintain visual coherence.

31. Use the 60–30–10 rule for balancing colors: — 60% dominant color, 30% secondary color, and 10% accent color, to create a visually harmonious interface.

32. Understand Color Psychology and Cultural Significance: Consider how different colors evoke different emotions and meanings in various cultures. Tailoring your color choices to your audience can enhance the user experience and avoid cultural missteps.

33. Communicate Status with Semantic Colors: Use colors to communicate status intuitively, like red for errors or green for success, to help users understand system feedback quickly.

34. Use Color to Guide Actions: Utilize color strategically to highlight key actions, like buttons or links, guiding the user’s attention to important interactions.

Effective visual content in UI design enhances user engagement and emotional connection

35. Prioritize Content Over Excessive UI Styling: Focus on delivering content through visuals without overwhelming the user with excessive UI decorations. Let the visuals speak for themselves.

Imagine a delicious pizza as your complex project. To understand how feature slicing works, let’s break it down slice by slice: easy to manage and delicious (to maintain)! 🍕

I will repeat what I said in my previous medium stories. This will be a long (because why not 😇) and maybe a little difficult to understand article. But once you read it and understand it perfectly, you will now be a 10x frontend developer. 😎 Let’s take your coffee. ☕️ If you don’t drink enough coffee, it will take you longer to become a 10x developer. 😅

I like to simplify web and mobile applications by dividing them into smaller parts called feature sets. Each feature set has its own user interface, business logic, and data layer, making it easier to handle. This method, called Feature-Sliced Design (FSD), shares advantages with component-based approaches. What stands out to me about FSD is its ability to break down web and mobile applications into more manageable pieces, especially focusing on user-centric features.

Structure

FSD methodology is built on three abstraction levels: layers, slices, and segments.

Layers and Slices

Imagine your app as a delicious pizza. 🍕 (As a developer working at Domino’s, it is my natural right to use the pizza analogy. 😎)

1. Shared Layer (The Pantry):

• Ingredients for everyone: Holds reusable components, utilities, hooks, and services that multiple slices can access. (Think of it as the shared kitchen where everyone can grab common ingredients and tools.)
• Examples:
  - Common UI elements like buttons, forms, modals and navigation bars (think of them as pre-cut veggies and cheese)
  - Utility functions for data formatting or validation (like a sharp pizza cutter)
  - Global state management solutions like Redux, Zustand, Tanstack Query (the recipe book for consistency)

2. Processes Layer (The Kitchen Staff):

• The hardworking chefs: Handles background tasks and data fetching, keeping the pizza kitchen running smoothly. (Think of them as the pizza chefs who prepare the dough, sauce, and toppings, and coordinate the baking process.)
• Examples:
  - Fetching pizza orders from the online system
  - Sending notifications when pizzas are ready
  - Syncing data with the delivery drivers

3. Features Layer (The Pizza Slices):

• Independent and self-contained: Each slice encapsulates a specific feature, with its own UI, logic, and data, like individual pizza slices with their toppings.
• Examples:
  - “Order Pizza” slice: Handles pizza selection, customization, and checkout (pepperoni, mushrooms, extra cheese, sucuk -sausage- you name it!)
  - “Track Order” slice: Displays order status and estimated delivery time (like a pizza tracker)
  - “Review Pizza” slice: Allows customers to rate and comment on their experience (a feedback form for the chef)

4. App Layer (The Pizza Chef):

• The head chef: Oversees the entire pizza-making operation, deciding which slices to bake and how to present them to customers. (Think of it as the master chef who designs the menu, creates new recipes, and ensures each pizza is cooked to perfection.)

5. Pages Layer (The Pizza Display):

• Arranges the slices: Composes slices into meaningful page layouts, like arranging pizza slices on a platter or delivery carton box.
• Examples:
  - Homepage: Combines “Featured Pizzas” and “Order History” slices
  - My Account: Includes “Personal Information” and “Order Preferences” slices

6. Widgets Layer (The Spices):

• Optional flavor enhancers: Small, reusable UI components that can be sprinkled across slices or pages/screens, like adding extra seasoning to your pizza.
• Examples:
  - Search bar (for finding your favorite pizza quickly)
  - User notification panel (alerting you when your pizza is ready)
  - Modal dialogs (for special requests or confirmations)

5. Entities Layer (The Raw Ingredients):

• Building blocks of data: Represents core business entities, like the flour, yeast, and toppings in a pizza.
• Examples:
  - User entity (storing customer details)
  - Pizza entity (defining pizza types and ingredients)
  - Order entity (tracking order information)

Key points to remember:

• Each layer has a clear responsibility and dependency direction.
• Slices can communicate with each other using well-defined contracts, like pizza slices sharing a common crust.
• The goal is to create modular, independent, and easily testable slices, making your “pizza” codebase more manageable and delicious!

Additional pizza analogy notes:

• The kitchen staff (processes) work behind the scenes, preparing ingredients and ensuring a smooth pizza-making process.
• The pizza chef (app) is the mastermind, orchestrating the creation of different pizzas (features) and deciding how to serve them up (pages).
• The raw ingredients (entities) are essential for any pizza, but they’re not always visible to the customer — they’re the foundation that makes everything else possible.

Segments (The Toppings):

• The ingredients within a slice: While a slice is a complete feature, it’s often made up of smaller parts, called segments. These are like the individual toppings that make up a pizza slice.
• Focused on specific tasks: Each segment has a clear responsibility within its slice, like handling a particular UI element, data operation, or piece of logic.
• Examples:
• Within the “Order Pizza” slice:
  - “Pizza Menu” segment: Displays available pizza options and prices.
  - “Topping Selector” segment: Allows customers to choose their desired toppings.
  - “Checkout Form” segment: Collects payment and delivery information.

With a more React way:

Each slice is split into one or more of the following segments:

• ui/: User Interface components and UI related logic
• model/: Business logic (store, actions, effects, reducers, etc.)
• lib/: Infrastructure logic (utils/helpers)
• config/: Local configuration (constants, enums, meta information)
• api/: Logic of API requests (api instances, requests, etc.)

Key points to remember:

• Slices are larger, self-contained features, while segments are smaller, focused parts within a slice.
• Each slice can have multiple segments, just like a pizza slice can have various toppings.
• The goal is to create well-organized, modular code that’s easy to understand, develop, and maintain — like making a pizza with beautifully arranged toppings, each adding its unique flavor to the whole pie!

How about exemplifying what we have read so far in code?

1. Folder Structure (The Pizza Kitchen Organization):

2. Order Pizza Slice (The Extravaganzza):

// features/order-pizza/slice.tsx
import React from 'react';

interface OrderPizzaSliceProps {
  // ... slice props
}

const OrderPizzaSlice: React.FC<OrderPizzaSliceProps> = ({ /* ...props */ }) => {
  // ... slice logic and state management

  return (
    <div>
      <PizzaMenu />
      <ToppingSelector />
      <CheckoutForm />
    </div>
  );
};

export default OrderPizzaSlice;

3. Pizza Menu Segment (The Dough Base):

// features/order-pizza/components/PizzaMenu.tsx
import React from 'react';

interface PizzaMenuProps {
  // ... pizza options
}

const PizzaMenu: React.FC<PizzaMenuProps> = ({ /* ...props */ }) => {
  // ... fetch pizza options and display them

  return (
    <ul>
      {/* List of pizza options */}
    </ul>
  );
};

export default PizzaMenu;

4. Homepage (The Pizza Display Counter):

Feature-Sliced Design (FSD) is like slicing that pizza into neat, individual pieces, each with its own toppings and flavor. Here’s the good and not-so-good of this approach:

// pages/HomePage.tsx
import React from 'react';
import OrderPizzaSlice from '../features/order-pizza/slice';

const HomePage: React.FC = () => {
  return (
    <div>
      <h1>Welcome to Domino's Pizza!</h1>
      <OrderPizzaSlice />
    </div>
  );
};

export default HomePage;

Key takeaways from the code:

• Clear folder structure: Each slice has its own folder, keeping its components and logic organized.
• Independent slices: Each slice can be developed and tested independently, like a self-contained pizza.
• Reusable components: Shared components (buttons, inputs, etc.) can be used across slices for consistency and efficiency.
• Composition within pages: Pages combine slices to create meaningful layouts, like arranging pizza slices on a platter.

Remember: This is a simplified example. Real-world FSD involves more complex state management, data fetching, and communication between slices. However, this example demonstrates the core principles of organizing React apps using FSD.

The good stuff (slices):🍕

• Easy to manage: Like separate pizza slices, each feature is self-contained, making code easier to understand, fix, and update. No more domino effect when changing one part!
• Scales like crazy: Need more features? Just add more slices! FSD lets your app grow gracefully, adapting to new needs like adding pepperoni to your veggie delight.
• Faster cooking (development): Different teams can work on separate slices at the same time, speeding up development like having multiple chefs making pizzas.
• Clear ownership: Each slice has a designated “pizzaiolo,” making developers responsible for its quality and performance, similar to how each chef takes pride in their creation.
• Testing made simple: Testing becomes like checking each slice for doneness, making it more focused and efficient.

The not-so-good stuff (crusts):👎🏻

• Trickier planning: Slices need to work together seamlessly, like ensuring the cheese doesn’t spill over when joining them. Careful planning and communication are key to avoiding a pizza mess.
• Learning curve: Newcomers might be initially confused by the distributed nature of the “pizza,” like figuring out where to find the pineapple chunks. Good documentation is essential to help them navigate.
• Extra effort for teamwork: Ensuring communication and smooth connections between slices takes time and attention, like coordinating the chefs to build the perfect pizza together.
• Potential redundancy: Sometimes, two slices might have similar ingredients, like having both mozzarella and ricotta. Careful planning and shared resources can help avoid unnecessary duplication.
• Limited tools: FSD is still relatively new, so finding tools specifically designed for it might be like searching for a pizza cutter shaped like a unicorn. It might require some extra effort at first.

The decision:

FSD is like a great strategy for large and complex apps, but it’s not a one-size-fits-all recipe. Consider your project’s size, team, and development environment before diving in. Remember, even the most delicious pizza can be tricky to make if you don’t have the right skills and ingredients!
