UX design is the practice of designing user interfaces (UI) and their interactions. The goal of UI/UX designers is to create intuitive and usable designs that enhance the overall experience of using software or websites.

UX design has become an important part of every company’s marketing strategy. In fact, according to Forrester Research, companies spend over $1 trillion annually on customer experiences. This means that they want to ensure that their customers enjoy a positive experience when interacting with them.

UX designers often collaborate with other disciplines such as graphic designers, interaction designers, information architects, developers, etc., to develop a cohesive user experience. They also work closely with stakeholders to gather requirements from clients and translate those into functional specifications.

Absolute Position: The position of something is said to be absolutely fixed when it cannot move at all. For example, if we say that a table is absolutely fixed, then we mean that it can never move. It does not matter how much force is applied to it; it will always remain where it is.

Relative Position: A relative position means that one thing moves relatively to another. For example, if I tell you that the sun rises every day, this means that the sun rises relatively to me (the earth). If I tell you that the moon orbits around the earth, this means that the moon orbits relatively to the earth.

Static Position: A static position means that something stays in its original place without moving. For example, if someone tells you that a tree has been standing there since time immemorial, this means that the tree has remained in its original place without changing its position.

Fixed Position: A fixed position means that something remains in its original place without any movement. For example, if a person says that he/she has been sitting here for years, this means that the person has remained in his/her original place without moving.

An interface is defined as the set of actions and controls that allow people to interact with a computer system. This includes hardware components like keyboards, monitors, mice, printers, etc., as well as software components like applications, windows, menus, icons, etc.

There are two main types of user interfaces: graphical and textual. Graphical interfaces include Windows, Mac OS X, Linux, Android, iOS, etc. Textual interfaces include command line interfaces, menu driven interfaces, and dialog boxes.

GUI stands for Graphic User Interface. In general, GUIs have more features than CLIs. However, they also require more training and knowledge on the part of the users. On the other hand, CLIs are easier to use because they don’t require any special training. They are easy to learn and understand. Also, some commands may take longer to execute than others.

A good user experience depends on the type of device used by the end user. Since each device has its own unique characteristics, the same application needs to be designed differently for each device.

Responsive design refers to web pages or websites which change their layout based on the size of the screen being viewed. Responsive designs make sure that the content appears correctly on mobile devices such as smartphones, tablets, and phablets.

A responsive website adapts automatically to fit the screen size of the device it’s being viewed on. An adaptive website requires manual adjustments to ensure that the website fits the screen size of the viewer.

Mobile-first approach focuses on creating a great user experience on small screens while keeping the desktop version intact. The mobile-only approach focuses on developing one single version of the site and then making it available across all platforms.

The best way to improve your user experience is to listen to what your customers say about your product. You can ask them directly through surveys or focus groups. Or you can analyze data from social media sites like Facebook, Twitter, Google+, etc.

The following factors play a significant role in designing a successful user experience:

  • Usability – It is important to keep the interface simple, intuitive, and easy to navigate.
  • Accessibility – Make sure that the information provided is easily accessible to everyone.
  • Consistency – Ensure that there is consistency among various parts of the system.

UI UX design is a rapidly growing field that is essential for any modern web or mobile app. The success of any product relies on the user experience, and a good UI UX designer can make a huge difference in the way people interact with a product. You’ll need to have strong visual design skills where you will from the best UI UX Online Course to get a great job which you can achieve with ease.There are many different aspects to UI UX design, from understanding user needs and creating a clear and intuitive design to helping developers build interactive features that users will prefer.

Usability is defined as the ease of learning how to use a particular software or hardware product. There are three basic principles of usability:

  • Understandability – Users need to know what they’re doing at every step of the process.
  • Learnability – Users must be able to figure out how to perform tasks without having to read instructions.
  • Operability – Users must be capable of performing tasks with minimal effort.

Interaction design involves the creation of interfaces that allow people to interact with computers and other electronic products. These interactions include mouse clicks, keyboard presses, and gestures.

Touch devices have a touchscreen display. They are usually smaller than non-touch devices. Touch devices are also more expensive than non-touch devices because they require additional components such as sensors, cameras, and processors. Non-touch devices do not have a touchscreen display but still offer similar functions as touch devices.

Visual hierarchy refers to the order in which different objects appear on a page. This order determines the importance of each object. For example, if an image appears on top of another image, it will be seen before the second image. If an image appears below another image, it will appear after the second image.

Navigation is the path users follow when moving around a website. Content is the text and images used to communicate ideas and messages. Structure is the arrangement of these elements within a web page.

Wireframes are low fidelity mockups that show the layout of pages and their overall look and feel. Prototypes are high fidelity mockups that contain all the details of a site’s design including colors, fonts, graphics, and animations.

Cognitive load refers to the mental workload required by a person while using a computer or mobile device. Cognitive loads vary depending on the complexity of the task being performed. A complex task requires more attention and concentration than a simple one. Therefore, a user may experience higher levels of stress during the performance of a complex task. The goal of any website is to reduce this level of stress so that users can focus on the task at hand.

Information architecture (IA) is the organization of information into meaningful groups. It helps users find relevant information quickly and efficiently. IA is often overlooked in the process of designing a website. However, it is critical for effective usability.

A front end developer creates the code that makes up the interface of a website. A UI developer designs the interface. Both roles are important but the UI developer has more responsibility since he/she is responsible for creating the final product.

CSS stands for Cascading Style Sheets. It allows designers to create style sheets that control how HTML elements are displayed on a webpage.

Document Type Definition. It defines the format of the document. In other words, what type of file you are dealing with.

Extensible Hypertext Markup Language. It is a markup language designed specifically for Web documents. It was created to make it easier to write standards compliant documents.

CSS gives us many benefits such as flexibility, maintainability, portability, and extensibility. Flexibility means that we can change the appearance of our website without having to rewrite the entire thing. Maintainability means that we don’t have to worry about updating the CSS every time there is a new version of a browser. Portability means that we can use the same stylesheets across multiple platforms. Extensibility means that we can add new features to our website easily.

Inline Element: These elements appear directly inside another tag. They do not take up space in the flow of the page.

Block Element: These elements take up space in the page flow. Block elements usually surround text or other content.

Inline-Block Element: This element behaves like an inline element. But unlike inline elements, they wrap around their contents.

Relative Position: This position is based on the current position of the object. For example, if I want to place a div over my image, then I would set its position to relative. If I wanted to move it down, I would set the top property to -50px.

Positioning: There are three main ways to position an element on a web page. The first one is static positioning. Static positioning places an element at a specific location on the screen. The second way is absolute positioning. Absolute positioning moves an element from its normal position to a specified point on the screen. Finally, fixed positioning keeps an element in a particular spot on the screen regardless of scrolling.

Absolute Position: This position is similar to static positioning except that it doesn’t depend on any parent element. An example of this would be placing a button on the bottom right corner of the screen.

Width: You can get the width of an element by using the getAttribute() method.

Height: You can get the height of an element by using either the getAttribute() method or the innerHeight property.

Checking whether an element has been pressed: To check whether an element has received a click event, you need to use the.addEventListener() method.

AJAX (Asynchronous JavaScript and XML): Ajax is a technique used to transfer data between two separate parts of a webpage. It uses HTTP requests to send information back and forth.

Window: A window is the area where all your code runs. It contains everything that you write in JavaScript.

Document: A document is the actual file that holds all the HTML, images, etc.

Reset.css: Reset.css is a style sheet that resets the default values for most browsers.

Normalize.css: Normalize.css is a style guide that helps make websites more accessible. It makes sure that every browser displays the same things in the same way.

Web accessibility refers to making websites easier to read, understand, navigate, and interact with for people who have disabilities.

Aria Attribute: ARIA stands for Accessible Rich Internet Applications. It is a standard that defines how to create applications that work well for users with disabilities.

Hoisting: Hoisting means moving a function declaration to the top of the scope so that it executes before other functions.

DOM: Document Object Model is a collection of objects that represent the structure of a document.

CSSOM: Cascading Style Sheets Object Model is a specification that allows developers to access stylesheets through JavaScript.

There are many important factors that go into UI UX Design, but usability and visual design are two of the most important. When designing a user interface, it is important to make sure that the design is easy to use and visually appealing.Well-designed user interface (UI) will be easy to use and visually appealing with FITA Academy’s UI UX Training in Bangalore. This will help users feel comfortable and confident using the interface, and will lead to increased productivity.

Event Bubbling is when events propagate up the DOM tree until they reach the root node.

When a user clicks on a link, the href attribute gets changed. But when the user clicks on the link, the href attribute does not change. This is because the event was handled by the anchor tag itself. So, we say that event bubbling occurs here.

Event Propagation: If there is no event handler attached to the target node then the event will propagate up the tree until it reaches its parent. The event handlers are called at each level.

Event Delegation: In case the target node does not handle the event, the event will be delegated to the nearest ancestor which handles the event.

Event Capture: If the event bubbles from the child nodes to their parents, but the event never reaches the target node,then this is known as event capture.

Event Target: An event may bubble up the hierarchy, but if the target node is not interested in handling the event, it will ignore it.

Wireframe: Wireframes help designers visualize an idea or concept without having to worry about implementation details. They can focus on the design rather than the technology.

Prototyping: Prototypes are used to test out ideas quickly. You can use them to see whether something works or not.

A prototype is a representation of an object. It is similar to a blueprint.

Mockups are usually created using Photoshop. Mockups are used to show designs to clients.

A wireframe is a visual representation of a website. It shows the basic layout of the site.

  • Aesthetics Usability Effect: When a product has good aesthetics but poor usability, it tends to sell better than a product with good usability but bad
  • Why does the Aesthetics Usability effect happen? Because most people judge products based on their appearance first, and only after judging the quality of the product, they decide to buy it.
  • How to avoid Aesthetics Usability Effect? Make sure that the product looks nice and appealing.
  • How to make good aesthetics? Use colors and fonts that match the brand’s image.
  • How to improve usability? Provide clear instructions for how to use the product.

Prototypes and mockups are two different types of design tools. A prototype is a low-fidelity version of a product that is used to test the feasibility of an idea. A mockup is a high-fidelity version of a product that is used to test the aesthetics and user experience of a product.

Color Theory: Color theory deals with how colors affect people’s emotions. For example, red is a warm color while blue is cold.

Psychology: Psychology helps us understand human behavior. For example, we know that humans have a natural tendency to avoid pain.

  • Style Guides: These are guidelines for designing websites. They contain information such as typography, spacing, color, and other things.
  • User Interface Designers: UI designers create these guides.
  • Web Developers: Web developers make changes to web pages according to the style guide.
  • Users: Users view the sites and provide feedback.
  • Businesses: Business owners decide what they want to include in the style guide based on their needs.

User Interface (UI): This refers to all the elements of a computer program or system that allow users to interact with it.

Implementing Accessibility Features: Implementing accessibility features makes a website accessible to
