mostly, when people think of design, we think about how something looks. on the web, the first matter of business is designing how the site works. Before you consider colors and fonts, it is paramount to identify the site’s objectives, how it will be used, and how visitors move through it. these tasks falls under the disciplines of User Experience(UX) design, Interaction Design(ID), and User interface design. This is a lot overlap between these responsibilities, and it is not uncommon for one person or a team to handle all three.
The user Experience designer takes a holistic view of the design process by ensuring the whole experience with the site is favorable. UX design is based on a solid understanding of users and their needs based on observations.
For a website or application, that includes the visual design, the user interface, the quality and message of the content, and even the overall site performance. The experience must be in line with the organization’s brand and business goals in order to be successful.
The goal of the Interaction Designer is to make the site as easy, and efficient to use as possible. closely related to interaction design is User interface, which tends to be more narrowly focused on the functionality organization of the page as well as the specific tools(links, buttons, and so on) that users use to navigate content or accomplish tasks.
