Responsive web design relies on flexible layouts and grids, CSS media queries, and responsive images to deliver adaptable websites.
In 2025, mobile e-commerce represented about $2.5 trillion in sales. Data suggests that by 2029, mobile orders will account for 63 percent of e-commerce [1].
With responsive web design, websites provide an optimized appearance and usability because they automatically adapt to the type of device you use.

What does responsive web design mean?
Responsive web design (RWD) refers to designing websites to adapt to a user's device. The goal is for a website to retain its optimal usability and appearance regardless of the device it's displayed on. Responsive web design responds to user needs by adapting to different screen sizes, orientations, layouts, and platforms. This is accomplished with the use of flexible grids and layouts, responsive images, and CSS media queries.
RWD meaning
Responsive web design emerged as a concept and approach to building websites in 2010 with web designer Ethan Marcotte's article “Responsive Web Design," which appeared in A List Apart [2].
What is the purpose of responsive web design, and why is it important
Responsive web design benefits users, web designers, developers, and businesses. For example, it allows web developers and designers to build a site once for a range of devices rather than building a desktop version and a separate, mobile-friendly design. RWD makes it possible to build one adaptive website rather than needing to create a mobile version alongside the one that's optimized for desktop browsers.
The mobile-friendliness of responsive web design also creates a better user experience for the many people who do their internet browsing, shopping, and banking on their phones. According to Statista data released in 2025, $2.5 trillion in retail orders worldwide came from smartphones, with projections that mobile will continue to grow, reaching 63 percent of all e-commerce orders by 2029 [1]. Responsive web design can also boost your site’s SEO performance. Search engines like Google favor user-friendly sites that engage visitors with quick load times, responsive layouts, and otherwise seamless user experience (UX).
You can learn RWD online with no previous experience in just two months by enrolling in CalArts' UI/UX Design Specialization:
Responsive web design vs. adaptive design
As you research responsive web design, you're likely to come across the term adaptive web design as well. You can use the table below to compare these similar terms.
| Responsive web design | Adaptive web design |
|---|---|
| Dynamically changes a site’s page layout based on a device’s display type, width, height, etc. | Detects the screen size and loads the appropriate layout for it |
| Uses CSS media queries to change styles | Uses static layouts based on breakpoints that don’t respond once they’re loaded |
| A designer creates one flexible layout that changes according to device | Requires creating a different layout for every device, for example, separate web and mobile versions |
| Works best for larger sites that are being designed for the first time | Works best for smaller sites that need to be redesigned or refreshed |

How does responsive web design work?
This next section explores some programming languages, markup languages, web technologies, and mechanisms that make RWD possible.
Elements of RWD
Media queries: Alter web designs based on a user’s device
Flexible images: Sometimes called adaptive images because they have no fixed display size limitations. This versatility makes it easier to resize images neatly.
Fluid grids/fluid layout elements: Automatically rearrange columns of content to fit different screens or browser windows
Code for flexible layouts: Resize page elements to fit different screens or browser windows
HTML (hypertext markup language): A programming language that determines the content and structure of a webpage
CSS (Cascading Style Sheets): A programming language that determines the design and display of HTML elements.
