Responsive Web Design Guidelines: What It Is and How to Use It

 Before getting into the details of responsive web design guidelines, let’s have a short background introduction. The responsive web design, firstly put forward by Ethan Marcotte, is not just about the adaptiveness of screen resolution or the auto-scaling of pictures. Instead, it’s more like a new way of thinking where designers need to consider many factors, such as the device performance, Dom node number and the screen size, etc. Following are several responsive web design techniques for your reference.

How about responsive product design? 

The responsive design is out of the product design, which requires the engagement of product managers, interaction designers as well as engineers. It’s of necessity for us to break the traditional way of thinking in the design, shifting from the web to mobile applications. The first step is to build a clear information architecture, then get the design started on the smallest display of mobile devices with the abandon of interference so as to ensure the best experience of the core function.

Meanwhile, the participation of interaction designers should deal with the responsive design problems and the issue of how to make the module much smaller and flexible. They also need to confirm the design style and framework. For the developing engineers, their responsibility is to make the test of coding and programming on the basis of the completed project, taking full advantage of individual device’s characteristics and building frame structure.

How does the interface design look like in the RWD? 

 Previously, most of the interface designs aim to the desktop products, and there will be one single size with fixed location of each module. But everything has changed in the responsive design. According to those responsive web design tutorials on the web, it proves that designers need to make multiple versions of design. A typical example is the module A which is shown in a black background in the width of 1024px is shown in a white background in the width of 768px.

Does the traditional media query breakpoints still go popular? 

From the perspective of traditional design, it’s possible to change the page layout through Media Query. For instance, we can change the layout in a fixed width (that’s what we call breakpoint). The usual way of thinking is to set breakpoints in accordance with some devices, such as desktop, tablet and mobile phone. As a matter of fact, the media query breakpoint is unreliable as the screen size will continue changing with the development of technology.

But the responsive design shouldn’t be targeted only at some devices with certain sizes, and there needs an interval value during the design process, rather than a resolution corresponding to a device. Henceforth, it’s necessary to make correspondent settings according to the content need. For designers, they need to find a critical point – that is the value when the visual effects start failing to meet the aesthetic of people or the acquisition of content.

What are the differences between interaction design and RWD?

In the responsive design, it requires a comprehensive consideration about the way of interaction, which is one of the responsive web design key features. An excellent interaction designer should not only consider the habits of desktop users, but also must take the portable devices of different sizes into account. For instance, we’re used to using the floating layer on PC, but it cannot be used on some devices of small sizes. Also, some links of a small responsive area are not easy-to-operate by fingers.

This requires designers to seek common ground while reserving differences. For example, they can decide whether to use floating layer, increase the operating area and keep unified or not, on the basis of screen size. To ease the process of design, we’d like to recommend a simple-yet-powerful prototyping tool – Mockplus. It enables rapid prototyping and highly-visualized interactions with the simple drag-and-drop option.

In Conclusion

Above are the responsive web design guidelines for product design, interface design, media query breakpoints and interaction process. Hopefully, you can find it helpful, and you can also learn about the difference between responsive and adaptive design.

What is Mobile First Design? Why It's Important & How To Make It?

On the Mobile World Congress in 2010, Eric Schmidt, the CEO of Google put forward that designers should follow the “mobile first” rule in product design. What does “mobile first design” mean? Why is it important? How to make it? I’ll answer these 3 questions in the following part.

What is Mobile First Design?
To understand the concept of mobile first design better, you should know the two phrases below first.

1. Responsive Web Design (RWD)
Responsive web design is a web design method that enable web to fit to the screens of different devices automatically, displaying the content in a way that people feel comfortable. This greatly reduces users’ operations like panning, zooming and scrolling when browsing the web.

2 “Progressive Advancement” & “Graceful Degradation”
These two concepts were put forward before responsive web design. In order to make web or application interface display reasonably on different devices, designers provide customized versions of product for different ends.

Progressive Advancement means that when we design a product, first we build a version for relatively lower browser (like that on a mobile phone). This version includes the most basic functions & features. After that we tend to the advanced version for a tablet or PC, which is created by adding interactions, more complicated effects, etc. on the basic version for a better user experience.

“Graceful Degradation”, on the contrary, starts the product design from an advanced end like desktop and builds a version with well-rounded features at the beginning. Then designers make the product compatible to mobile ends by cutting some functions or contents.

Progressive Advancement has won the game for now as far as I can see. If UI/UX designers start a product design with its desktop version, they will inevitably want to make use of most of the advantages of the advanced end. For example, the hover effect which is supported by a cursor mouse; HD images & complex charts which can display normally only when there is a recent bandwidth. In this way the designers will make efforts to complete an amazing desktop version and only to find it can hardly be adopted on a mobile end unless they give up a lot of beautiful ideas. If so, the mobile end version will be more like an afterthought, an incomplete product which’s been watered down.

But if we take the mobile end product design as a starting point, under the restrictions like bandwidth, screen size and so on, designers will naturally seize the key points of a product, head for a lean & neat product with prioritized features. When the platform is expanded to a tablet or PC, designers are able to take advantages of the unique features of these advanced ends to strengthen the product step by step. This might be the main reason that progressive advancement strategy is widely used.

You may ask, why do you spend so much time on explaining the two concepts? The answer is that “mobile first” is exactly a rule of “progressive advancement”.

"Mobile first", as the name suggests, means that we start the product design from the mobile end which has more restrictions, then expand its features to create a tablet or desktop version.

Why "Mobile First" Principle Is So Important in Product Design?
Except for the victory of progressive advancement against graceful degradation as mentioned above, we have more tangible reasons to believe that mobile first principle is important in product design. That is, the exploding of mobile use.

1. Mobile internet usage has surpassed desktop usage in 2016.

2. People have spent more and more time on internet from mobile ends.

3. Early in 2012, smart phone sales have overtaken PC sales.

The exploding of mobile ends urges designers to pay attention to the mobile end and follow the “mobile first” rule in product design.

How to Practice “Mobile First” Rule in Product Design?
The key to mobile first principle is, in fact, a content-centered mind.

The following part will explain the advancement of a product from a mobile phone end to a PC end.
(The design tool used in the example below is Mockplus by Jongde software company. Mockplus is an easy-to-use PC/mobile application for fast wireframe & prototype building)

Let’s make an application about hotel booking. We first sort the content of the site by importance:
* Website name
* Hotel (Domestic Hotel, Foreign Hotel, Hour Room, Special Hotel)
* Time selector (check-in time, departure time)
* My Order
* Customer service
* Promotion & Advertising

Then we get a mobile end version like this:

Hotel Booking App

Domestic, foreign hotels and time selectors are the most important content. They are located on the most prominent part of the interface.

By adding more features on the mobile version and enlarging the promotion & advertising displaying area we get a desktop version like this:
Ads & Promotion responsive design

In this way, designers are able to creating a product for multiple ends in a smooth and efficient way instead of ruthlessly removing those good features to get an afterthought.

In short, the "mobile first" principle has an important role in product design. On the one hand, it helps to save product design time and improve designers’ productivity. On the other hand, it forces designers to pay more attention on the content of a product, which helps them to created neat and practical designs. However, as smartphones become more and more powerful, the mobile end might no longer be considered as “lower ends" in the near future, so the "move first" may not be an everlasting topic. But for now, its place in product design cannot be ignored.
