Web design refers to the design of websites that are displayed on the internet. It usually refers to the user experience aspects of website development rather than software development. Web design used to be focused on designing websites for desktop browsers; however, since the mid-2010s, design for mobile and tablet browsers has become ever- increasingly important.

Two of the most common methods for designing websites that work well both on desktop and mobile are responsive and adaptive design.In responsive design, content moves dynamically depending on screen size; in adaptive design, the website content is fixed in layout sizes that match common screen sizes. Preserving a layout that is as consistent as possible between devices is crucial to maintaining user trust and engagement.
