Responsive Web Design: Explanation

Responsive web design is a crucial factor in ensuring an optimal user experience and good search engine rankings. Its importance is growing over time as more and more users access the Internet via mobile devices.


Responsive web design is important because it ensures that your website is visible and functions properly on all devices, from desktop computers to mobile devices such as smartphones and tablets. This improves the user experience, as users can easily access your website from any device, without navigation or formatting issues. In addition, responsive web design is also important for search engine rankings, as search engines such as Google prefer responsive websites, which provide an optimal user experience for all users. Investing in responsive web design is therefore critical to ensuring the success of your website.

Responsive Design and its Evolution over Time

The evolution of responsive web design has been influenced by the growing popularity of mobile devices and the need to ensure an optimal user experience on these devices. In the past, websites were designed to be viewed only on desktop computers and were not optimized for mobile devices. As the use of mobile devices to access the Internet increased, it became necessary for websites to be displayed properly on these devices.
The concept of responsive web design was introduced in response to this need and has evolved steadily ever since. Initially, responsive websites were designed using only CSS, but later other tools and technologies for creating responsive websites were introduced, such as grids and frameworks such as Bootstrap.
L’evoluzione del design web responsivo continua ancora oggi, e va in parallelo con la nascita di nuovi formati e tecnologie dei device.

What is Responsive Web Design


The term “responsive” in the context of Web design refers to the ability of a Web site to respond and adapt to different screen sizes and the different devices on which it is displayed. This means that the website automatically adapts to screen width and device resolution, ensuring an optimal user experience on every device and in every orientation.

The etymology of the term comes from the English “sensitive, responsive.”

Responsive Web - Multi Device


Benefits of responsive web design include:

  1. Better user experience: responsive web design makes your website easy to navigate and use on desktop computers, smartphones and tablets.
  2. Increased accessibility: with responsive web design, your website is accessible from any device, wherever you are. This means that users can access your website from anywhere and at any time.
  3. Search engine ranking: search engines such as Google prefer responsive websites, you are then more likely to rank high in search engine results, increasing your visibility.
  4. Reduce costs: with responsive web design, you can create a single website that works properly on all devices, without the need to create separate sites, I will explain this further by explaining the difference between adaptive and responsive.

Importance of responsive web design in UX

How responsive design affects user experience

Ease of use and navigation are key factors for a positive user experience on your website. If a website is not easy to navigate or use, users are more likely to leave the site and look for alternatives. Have you ever found yourself interacting with your cell phone on a non-mobile web site? Here’s that uncomfortable feeling of trying to read, zooming in literally makes your visitors run away.
Conversely, if a website has a great user experience, users are more likely to stay on the site, explore it, and interact with it in any condition and on any device. In the next section this concept also ties in with SEO positioning, but first I want to show you my work.

Examples from my Webfolio

All the sites I do are clearly web responsive. Check them out here in my Webfolio.

Let me tell you a little introductory anecdote: when I started with website creation, the concept of responsive design did not yet exist. There were no iPads yet and we were all walking around with Nokia’s that at best sent text messages! So the problem did not arise. Subsequently, with the advent of the aforementioned devices, designing responsive has become an indispensable technical aspect for a web designer who deserves to be called one.

Today there are premade templates that already have a responsive structure, however, subsequent optimization needs to be done to improve performance and thus stand out online in searches. That’s why it is important not to rely on do-it-yourself, but to contact a professional web designer.

How responsive design affects search engine rankings

Responsive web design has a strong positive impact on your site’s search engine ranking. For example, Google prefers responsive websites because these sites provide an optimal user experience for all users, who are therefore more likely to stay on your site, explore it and interact with it, which is considered (not only by the algorithms) a quality factor.

Why Google prefers responsive websites

Responsive web design allows the content and structure of the website to be optimized for mobile devices, which account for an increasing percentage of global web traffic. Google considers user experience on mobile devices as a ranking factor.

Strategies for ranking well with responsive design

To achieve good search engine rankings with responsive design, it is important to follow some strategies. It is important to optimize website content for search engines, using appropriate keywords and creating quality content that meets users’ needs. In addition, it is important to use good website architecture and navigation so that users and search engines can easily and naturally access all pages of your site. A good design invites ever-changing actions based on the viewing device.

Difference between adaptive web design and responsive web design

Adaptive web design and responsive web design are two different approaches to designing a website to ensure an optimal user experience on different devices.

Adaptive web design involves creating different versions of the website for different screen sizes, such as desktops, tablets, and mobile devices. Each version of the website is designed to fit the specific screen size and provide an optimal user experience on that device. However, this approach requires more maintenance and can lead to usability problems on devices with intermediate screen sizes.

Responsive web design, on the other hand, involves creating a single version of the website that dynamically adapts to the screen size of the device being used. This means that the website resizes and rearranges itself according to the size of the screen. This approach is easier to manage and ensures an optimal user experience on any device, without the need to create separate versions of the website.

In summary, responsive web design is a more flexible and easy-to-manage approach than adaptive web design because it ensures an optimal user experience on any device with a single version of the site. However, adaptive web design can provide an even more optimal user experience on specific devices if designed correctly. I prefer responsive web approach

Media Queries and what role they play in responsive design

Media queries are a crucial element of responsive design. They allow the layout and content of a website to be adapted according to the characteristics of the device used to view it, such as screen width, resolution, and device type.

Media queries consist of a CSS rule that specifies how the layout and content of the website should be displayed based on certain conditions. For example, a media query could be used to specify that if the screen width is less than a certain width, the website layout should be modified to fit the smaller screen size.

In summary, media queries are a key element in ensuring that responsive design works as intended, adapting the layout and content of a Web site based on the characteristics of the device being used.

Most Common Breakpoints in Responsive Design

Responsive breakpoints are specific points at which the layout and content of a website are adapted to suit the characteristics of the device used to view it. The amount and size of breakpoints depends on the specific project and design requirements.

Usually, the most common breakpoints are:

  • Breakpoint for smartphones: screen width less than 480px
  • Breakpoint for tablet: screen width between 481px and 768px
  • Breakpoint per laptop: larghezza dello schermo compresa tra 769px e 1024px
  • Breakpoint for desktop: screen width greater than 1025px

However, these are only examples and could vary depending on the design and screen size of different devices, which are constantly evolving. In this regard, I leave you with a link to Bootstrap’s breakpoints, which represent a valid current average standard.

We can also say that there is no fixed quantity or absolute standards for responsive breakpoints, as they depend on the specific project and design requirements, such as the size of a particular graphic element.

Conditions also change depending on the orientation of the device, as in the infographic below:

Possiamo anche dire che non esiste una quantità fissa o una dimensione standard per i breakpoint responsive, poiché essi dipendono dal progetto specifico e dalle esigenze della progettazione, come ad esempio la misura di un determinato elemento grafico.

Un cosiglio che vi do, da progettista è: provate, testate e sperimentate sul vostro progetto.

One piece of advice I give you as a designer is: try, test and experiment on your project. Multi-device debugging is a very important step for a web designer and must be done before delivering the project.


To sum up: responsive web design has become a key factor in user experience and search engine rankings. It ensures that the website is easy to use and navigate on any device, thus providing an optimal user experience. In addition, search engines, such as Google, prefer responsive websites, which can increase the site’s ranking in search results.

With a greater percentage of people browsing the Internet from mobile devices, responsive design has become an indispensable factor for website success. Investing in responsive web design is critical to ensuring the success of your website. It will not only improve the user experience and increase search engine rankings, but also increase the visibility and competitiveness of the site in the market. Therefore, it is important to give serious consideration to choosing a designer who is thoroughly familiar with the rules of responsive web design.
