The answer is simple – Responsive Web Design

For those who are totally new to the concept, Responsive Web Design is a design technique that thoroughly focuses on a user’s environment and behavior based on the orientation and size of his screen as well as the platform. This methodology integrates a blend of cleverly laid out grids and images combined with the smart usage of CSS Media Queries. What happens is that, when a user switches from his desktop or laptop screen to his iPad or iPhone, the website will automatically itself to fit the device’s screen.

In a nutshell, you could say you are empowering a website with a kind of artificial intelligence which lets it respond to the user’s environment. Responsive Web Design has gained tremendous popularity in the Web Design World as it eliminates the need of having different development and design phases for every different gadget in the Industry.

So if you are looking for inspiration for your next website, you should look at these fresh and stylish responsive design layouts (in no particular order) which cover a wide range of companies and design strategies. Here, we will focus on the mobile side of these responsive websites and try to take a look at what practices make these websites an inspiration to everyone who’s looking to transform their web design to function across multiple platforms and devices.

1. Sony

%tutke

Sony manages to get everything right in their elegantly designed website. My favorite part of their responsive design approach was seeing the way their navigation bars change when switching from desktop to mobile devices. On a mobile device, the main navigation menu will change places with the social media buttons. The menus also compact themselves into a single drop down button where the different pages can be accessed easily.

2. Starbucks

%tutke

Starbucks is unarguably one of the biggest retailers in the world and it was one of the first to make the jump to responsive web design. The minute you switch to mobile from desktop on this website, you get the feeling that they have a sizable team with a substantial budget working on the transformation. The first noticeable thing was that the initial breakpoint arrives at the 769px mark (I assume this has been done to accommodate the portrait orientation of tablets). The best thing about the design is that the navigation adapts itself automatically across different breakpoints. For example, at the largest breakpoint, the top level menu allows you to jump across two levels of navigation for viewing a page.

3. Aids.gov

aids.gov

Aids.gov‘s website is probably the first US government website that has made the switch to responsive web design. I noticed that they use the HTML5 doctype without the use of any additional HTML5 elements like articles, headers or sections. Specific attention has been paid to the website for how it is viewed by users on Windows IE Mobile 7. Aids.gov employs the standard responsive web design approach as the website was redesigned from scratch. The theory lies in working with the smallest screen size and resolution first and then building up the additional required CSS code as the breakpoints are increased. Responsive images have been incorporated to make the website more visually appealing with special emphasis on how the script dynamically recalculates the appropriate height and width of each image based on the screen size.

4. Dairy Queen

dairyqueen

If you want to feast your eyes on one of the most perfect examples of responsive web design, head over to the Dairy Queen’s official website. One of the best things about the design is the fluid slider motion for mobile devices. There is a strong emphasis on how visible the content is to users across multiple devices and screen sizes. The main navigation menu wraps up into a smart drop down box at the first breakpoint allowing users to easily navigate the different food categories. All in all, the website is a visual treat and a perfect execution of elegant and efficient responsive web design.

5. Alsacreations

alsacreations

This is one website that has taken a different responsive web design approach than most websites present on the Internet. Alsacreations doesn’t worry about maintaining all their elements and aspects of their desktop website when a reader switches to tablet or mobile. Instead, Alsacreations drops their image slider from widescreen display to square and even more, when the readers switch to mobile they will not be able to see any of the original elements except for the About button and the Email form in addition to the links for all other elements. This has been done keeping the views of the specific target audience in mind where the creators have kept in mind that most users opening websites from their mobile devices do it to get the brief company information only.

6. Gravitate

gravitate

It wouldn’t be fitting to have a design studio website without responsive website design on their own page, right? Even if you are a lone freelancer, you would want your website to reflect your design skills and portfolio and this is exactly the approach that Gravitate Design Studio has incorporated into their website. They have kept and simple yet elegant design without going over the top on borders or shadowing or other flashy elements. The menu buttons on the top compact and nicely re-arrange themselves when you switch to mobile giving users to access to every page on the website.

7. Spigot

spigot

This is another web design and development company that has flawlessly perfected the art of responsive web design for their website. Going through the pages, you cannot deny the fact that the entire layout has been designed to work without any errors on desktop and mobile devices. You would expect that the shifting and animated icons would lose their touch on mobile devices, but this is not the case with Spigot. Although it would have been difficult to make this design work across all devices yet they have pulled it off magnificently setting a truly inspiring example for others in the field.

8. Disney

disney

Entertainment giants Disney have a website which is a perfect example of coherent designing across all devices and platforms. Smaller resolution doesn’t necessarily mean that you have to compromise on content. The beauty of this responsive design is that the focus stays always on the content that matters. Photos and Videos are the main focus of attention whether you open it on a mobile device, tablet or your PC. However the only drawback from usability point of view on mobile devices is that the navigation doesn’t have direct access in mobile version and you have to make up for it with an extra click.

9. Food Sense

food-sense

Another excellent example of sharp responsive web design techniques is Food Sense. It uses wide screen resolutions to the maximum but when limited by width on mobile devices, it adjusts brilliantly by managing to still maintain its smooth flow and tidy outlook. However, one drawback I noticed with the Mobile version was the loss of the latest Tweets and Facebook plugin which can be seen on the full version under the navigation bar on the side column.

10. Skinny Ties

skinny-ties

There is no better definition of perfect responsive web design execution than Skinny Ties. The design is even more impressive considering that it was a complex website – an ecommerce one. You will find a unique navigation experience across all breakpoints and viewpoint resolutions but the best thing about is its exceptionally responsive handling on mobile devices. Despite the use of the hovering function on touch devices, all visual aspects remain intact.

11. Coca Cola

coca-cola

Soft Drinks giant Coca-Cola made their entry into the fast changing web design world with one of the most complicated responsive web designs I have come across so far. One of the noticeable features is how the content boxes on the right hand side automatically align themselves below the slider so the user has no viewing problems. One drawback I came across however was some minor bugs with the navigation on 240×480 portrait screens.

12. Clean Air Challenge

cleanairhanller

First thing you notice about Clean Air Challenge are the moving clouds in the background. Like many, I expected the website to lose this animation on mobile devices, but amazingly the animation stays smooth and balanced. In addition to that, the website intelligently transforms into a vertical format while still maintaining its other aesthetic elements for example you will lose the images of the main navigation icons when you move to your mobile device but when you scroll down, they will be visible to you in the footer.

13. Contents Magazine

contentsmagazine

Contents Magazine gives one of the best illustrations of how effective responsive web designing can keep the content of the website at the center and front at all times – regardless of the device or platform used. The designers have managed to create a near perfect design where the pre-issued illustrations dynamically wrap around depending on the different breakpoints. The best thing about the design is that a reader will find genuine pleasure in reading the various content on his mobile site as the responsive images adjust themselves and never act as a distraction.

14. Crayola

crayola

Crayola gives us a perfect example of how cleverly used responsive web design can lead to navigation and content being scaled down for users operating a mobile device. When you look at the desktop version, the website has loads of tabs for navigation but when you switch to a mobile device, you get to see only the important ones whereas a user-friendly accordion pops up to accommodate the main navigation bar.

15. Time

time

In this day and age, it has become essential for every news site to have a responsive web design since they have to cater to the needs of a large population of their readers who want access to all the latest news and stories on the go. Time gives us an example of a minimalistic responsive web design approach while at the same time it sets an example for other News websites and companies on how to design grids and menus for easy viewing on a mobile device.

16. Smashing Magazine

smashing

Smashing Magazine sets the example for absolutely perfect responsive web designing where they demonstrate how the original design and content of a website does not need to be sacrificed on mobile devices. The developers of this website have paid attention to accommodating virtually every single screen size and resolution. One of the best things about viewing this website in your mobile device is that the ads simply disappear. The left side bar and the main navigation bar all wrap up into a drop down menu giving a mobile user easy accessibility to all pages of the site. One drawback is the absence of the social media buttons and the RSS feeds subscription button which are only visible in the desktop version.

17. Polygon

polygone

Polygon stands out from the rest of the crowd in the Gaming websites industry combining stunning artwork and responsive web design architecture for a superb display across desktop and mobile devices. But one very obvious drawback is that the social media buttons disappear when you switch from desktop to mobile.

18. Ableton

ableton

Even if you have a relatively heavy sight, Abelton demonstrates that with intelligently written code, you can still deliver a vibrant color combination with a mix of bold imagery across all platforms and devices. With the need to incorporate both video and music, Abelton have managed to do keep the focus on the content while making sure the design is not sacrificed.

19. Burton

burton

Although Snowboard retail giant Burton have incorporated responsive web design nicely for most elements of their page, there is still a lot left to be desired. For instance, the main menu navigation bar on a mobile device is nothing but a simple drop down button. The Board Finder tool is also missing which would have been a great feature for customers who are on the go and who want to find the perfect snowboard for themselves.

20. Abduzeedo

abduzeedo

Although Abduzeedo has a lot going on for itself on the Desktop, it doesn’t quite live up to the same expectations on a Mobile device. For starters, the posts automatically align themselves on the grid which makes them look clustered and improper. Regarding the sticky navigation on the Desktop, it has become more of a trend these days although there are two different opinions regarding this.

75+ Mobile App Development Tutorials – Start Your App Success Today!

 

Mobile app development is big business and one of the areas of opportunities for creative individuals and small teams of developers to make a stand. It may take several attempts to design and implement a blockbuster App; however, if your App hit the top charts of e.g. Apple App Store your opportunities are amazing.

Apps are simply defined small software programs executed on mobile devices such as iPads, Android smartphones etc. Apps are often designed with a very specific and simplified set of functions and to be easy to use on small screens and everyone seems to love downloading tons off Apps. Just check out this collection of mobile stats to get an idea of the popularity and opportunities related to App development. Some of the numbers are from 2012, but 400 million accounts in Apple App Store and $5 billion in payouts to App developers sounds like sweat music for anyone with a development talent.

So how do you get started? First, you need to choose the target platform and architecture to use. I have previously described the different App architectures in an article at LinkedIn that you may want to check out. Please note that you may choose to develop hybrid and cross device compatible Apps, but often these may not be as powerful as native Apps for e.h. iOS or Android.

To help you get started with the decision and learning process, I have collected some of the best tutorials available free online and categorized them into the following sections: iOS, Android and Hybrid App and App-framework tutorials.
