in this chapter pushing the limits of web design to app or not to app setting records and changing the game combining the “three screens” into one never before has a computer so sophisticated fit into your hands — and responded so well to your touch. on the iphone, and even more on the ipad, the touchscreen interface makes navigating the web easier than using a television remote control, and far more interactive. anyone who has used a touchscreen — from 2-year-olds to great-grandparents — appreciates the ease with which you can tap, point, tilt, swipe, and shake the iphone, ipad, and ipod touch. from games to art projects, music to movies, recipes to homework, it’s more fun to surf the web on a touchscreen. in this book, we explore how best to design websites for these new touchscreen devices: the iphone, ipad, and ipod touch. from the challenge to reinvent interface design on the web to the latest techniques in html5 and css 3, this book is designed to help you appreciate where web design is going and how to make your website look its best along the way. smartphones and tablets are changing the way the world shares information and communicates. our goal in this book is to make sure that your website takes best advantage of all that these new devices have to offer. pushing the limits of web design we’ve always been skeptical of hype, and html5, with its new logo (see figure 1-1), has certainly gotten more hype than any new markup language in the admittedly short history of the web. in the past, only true web geeks got all excited about refinements to the underlying language of the internet. (and reading manuals and treatises about this subject is as sure a cure for insomnia as we’ve been able to find.) however, for good reason, both creative web designers and hard-core “code monkey” developers are excited about html5. visit the innovative sites already adding new interactive features with html5 and its companion css 3 (the latest version of cascading style sheets) and you can see the web is becoming a truly interactive place. figure 1-1: the new html5 logo is designed to help promote the new html5 standards. logo and website design by ocupop.com. using the latest in html5 and css 3, you can create highly interactive websites that work well on the iphone and ipad. if upgrading to the latest flavor of web design seems complex and intimidating — relax. everything you already know about creating web pages should help you; and as in any for dummies book, we don’t assume that you know all the answers already. in chapters 4-7, we take you from the basics of html and css to the latest in interactive design features that you can create by combining html5 and css 3 (with just a dash of javascript or php programming thrown in once in a while). bringing high-touch design to the web one of the biggest trends in web design is kind of a back to the future movement, where designers are dusting off old design textbooks and rethinking the limits to the web that people have settled on for more than a decade. because of advances in html5 and css 3 — including the ability to use any font and to add design features such as drop shadows with ease — you can now design more creative interfaces for the web. driven by the user experience made possible by the high-touch design space of the ipad, graphic designers are striving to create rich media — interactive sites that look as good as anything ever designed for print — and sometimes even better. in the early days of the web, the internet was ruled by the geekiest of the geeks. with all due respect to the programmers and system administrators who shaped the early days of the web, we think that most of them would readily admit that design isn’t their collective strong point. most developers wouldn’t understand the fuss about choosing just the right font or why color theory is a lost art in the world of code. (if you find yourself relating to this description, you’ll find design tips in chapter 3.) the big news in the world of ipad design is precisely that — design. over the past decade, the web has been dominated by programmers. the result is text-heavy pages, where navigational elements clutter the design space and users of web browsers settle for only a few common fonts. the best part of the iphone experience is not just the eye-pleasing and friendly navigation icons, it’s the beautiful way photos and videos come alive on the screen. studies have also shown that iphone and ipad users love their devices (janine sometimes sleeps with hers). the intuitive way you touch the screen to navigate, and the ease with which you can curl up with an ipad or iphone in a comfy chair, makes it an inviting device to browse an online photo gallery, such as the one shown in figure 1-2, or surf the web. figure 1-2: the high-resolution screen on the ipad makes it an ideal device for viewing photos and videos. as the new design possibilities of html5 and css now begin to transform the web, we think it’s safe to say that the next decade on the internet will be shaped more than ever by designers and that the world wide web will become a more beautiful and aesthetically pleasing place as a result. web designers are now experimenting with completely new approaches to interface design. in figure 1-3, you see one of our favorite examples of the first serious use of css 3 in an interactive website. at any time zone (www.anytimezone.com), you can drag the bar across the top of the page to compare time zones without reloading the page. the slider is smooth and the clean design helps focus your attention on comparing time zones. this relatively simple site delivers a rich, app-like experience rarely seen on the web. figure 1-3: using html5, the any time zone site can provide a rich, app-like experience in the safari web browser. reaching the broadest audience though the focus of this book is the ipad and iphone, we don’t ignore the desktop web, which, after all, is still where the majority of web browsing occurs. we demonstrate the latest and best design options for the iphone/ipad, and we also point out how you can gracefully adapt those designs to work on browsers on the desktop web as well. if you want to reach out to users on all the other mobile devices flooding the marketplace (such as the android, blackberry, or windows phone 7 platforms), check out mobile web design for dummies, by janine warner and david lafontaine. in that book, we explore how to reach the broadest mobile audience by creating extremely limited websites that work on the most basic mobile phone models or by setting up highly complex device-detection scripts and adapting your pages dynamically to fit a variety of screen sizes and other variables. in this book, we’re excited to leave those constraints behind and show you where web design is headed and what you can do when you design for the future of web design on the fastest growing part of the web — the touchscreen. pushing the limits of web design is still, well, limiting. some of the features we cover in these pages don’t work in all web browsers or mobile phones. similarly, not all sites designed with html5 work on the ipad. because html5 and css 3 aren’t equally supported by all web browsers, sites that are designed for one browser may not look the same in another, unless you write special code to address the unique tags supported by each browser. (you learn more about creating code that works well in many browsers in chapters 4, 5, and 6.) the most popular app on the iphone is (surprise!) safari the “gold rush” environment of the itunes app store includes a growing list of magazines, tv networks, and other businesses scrambling to launch apps for the ipad and iphone. at the time we wrote this chapter, the most popular app in the app store was angry birds, a silly game in which you use a slingshot to shoot birds at pigs. yeah, we wouldn’t have picked it to be the most popular app in the itunes app store a year ago, either. despite commercials in which users showcase apps by scratching on deejay turntables or slaying dragons or checking traffic reports, the most popular application on the iphone and ipad doesn’t even need to be downloaded from the app store — it’s already on the device when you take it out the box. the safari web browser beats all other apps in the touchscreen popularity contest — another reason why designing websites for these devices is worthwhile. people surf the web a lot more on the iphone and ipad than on any other mobile devices. as professional web designers, we hope that we won’t have to create different code for each browser forever, but we love the new features in css 3 so much we think they’re worth the extra effort. fortunately, safari is one of the best browsers when it comes to supporting html5 and css 3. the rapid adoption of smartphones by consumers and the growing popularity of tablet devices means that the number of people using limited, old-fashioned cell phones web browsers is quickly decreasing, but the mobile web still isn’t a perfect place for designers. wherever we provide instructions for how to create pages specifically for safari on the iphone and ipad, we try to include tips or techniques you can use to ensure that your web pages display well in more limited web browsers, such as internet explorer, which has been slow to adopt the new html5 and css 3 features. because we’re pushing the limits of web design, we realize that some of the code featured in this book may change over the coming weeks and months. in each example in this book, we show you what we think is the best approach now, and we encourage you to visit the website we created to accompany this book at www.digitalfamily.com/mobile, where you can find updates, code samples, and other resources to help you continue learning. to app or not to app apple’s compelling marketing campaigns have spread the idea that no matter what you want to do — take your blood pressure, plan your next trek to kilimanjaro, or buy a new car — “there’s an app for that.” an app is a small computer program. on the mobile platform, there are web apps, which run in a web browser, and there are native apps, which run on the operating system on your iphone or ipad. native apps must be downloaded from the itunes app store, which means that if you create an app, you as the developer have to set up an account with apple and submit each app to apple for review before it can be made available to consumers in the app store. the review process is increasingly controversial because apple rejects apps it doesn’t approve of, and even if your app is approved, the review process can delay the launch of your app by days or weeks. although we love the mobile web, and all that you can do when you design websites for safari on the iphone and ipad, we’re not against apps. we agree that nothing compares with a native app when you want to create the most rich, interactive features possible. if you want a race car game that lets you “drive” the car by tilting your iphone or ipad back and forth, you’ll need to create an app for that. accessing the accelerometer, location detection, and other advanced features often requires a native app. despite our love and respects for apps, we believe that the itunes app store has received too much hype. the bottom line is not everyone needs an app, but every website on the internet should be mobile friendly and designed to look good to the growing audience of web surfers on the iphone and ipad. some companies, such as amazon and american airlines, have created both. in figure 1-4, you see the amazon native app on the left and the highly interactive website at www.amazon.com on the right. if you choose an app over a mobile website, remember you need to create a different version of your app for every type of device — one for the iphone, another for the ipad, and then additional versions if you want your app to work on the android, blackberry, windows mobile, or another mobile operating system. here are just a few reasons that we recommend creating a website instead of an app: you can update websites faster and more efficiently. websites aren’t subject to the unpredictable (and sometimes long) itunes review process. you can develop a more direct connection with your audience. distributing an app through the itunes app store means you can’t track your customers’ actions directly or even keep their contact information for future sales. one well-designed mobile website can work well on all popular mobile devices, from the ipad to an android phone. (you don’t have to be a math genius to figure out that creating one website is more cost effective than having to code a series of apps.) figure 1-4: amazon.com created both a native app and a web app for the iphone. setting records and changing the game according to the mobile phone manufacturer ericsson, the amount of worldwide mobile data traffic every month now measures 225,000 terabytes (roughly equivalent to 45 million dvds of data). the iphone generates about 50 percent of that traffic, according to bytemobile, and studies show that ipad users like to surf the web even more. though early usage statistics vary wildly, the bigger screen of the ipad has resulted in users web surfing 21⁄2 times more often than iphone users. the amount of data traffic generated by the iphone is even more surprising when you consider that the iphone still isn’t available in many developing countries, and even in the united states it accounted for less than 15 percent of the total number of phones in use. mobile web traffic is predicted to grow 4,000 percent by 2015, largely because most of the phones in use by then will be equipped with sophisticated web browsers, along with the expected explosion in tablet devices, sparked by the success of the ipad. compared to the clunky navigation of early mobile devices, the iphone and ipad create a new and delightful user experience. here are a few of their game-changing features: multi-touch screen: the iphone and ipad “wow” users with interactive features, such as the ability to use your fingers to make pinching or opening motions to shrink or enlarge web pages, photos, and text. scrolling: zipping your finger down a web page or a list makes the page contents spin past like the wheels in a slot machine. accelerometer: this tiny gyroscope can tell when the iphone or ipad is moved, and in which direction, so shaking the device can be used to randomly change the song you’re listening to or clear the screen of a game so that you can start fresh, for example. the accelerometer also determines whether the device is being held in portrait or landscape mode. no manual: neither the ipad nor the iphone comes with a manual. the devices are so easy to use (and so inviting) that most people learn to use them by playing around with them. appreciating the impact of the iphone for years, developers have been talking about the mobile web and all the things that would be possible when the mobile internet reached the masses. year after year, pundits declared “the year of mobile,” but not until the iphone came along did the dream become reality. the iphone changed everything in the mobile world. from the moment apple ceo steve jobs strode on stage to introduce the iphone (shown in figure 1-5), a kind of over-the-top technological frenzy enveloped the mobile phone industry. on june 29, 2007, eager mac fans stood in lines that crawled around city blocks and waited for apple stores to open and sell the iphone. before the iphone became available outside the united states, enterprising travelers could buy one for $300 and sell it on the streets of moscow or bangkok for $2,000 or more. figure 1-5: the iphone deserves credit for driving the popularity of the mobile web. photo courtesy of apple, inc. the iphone was also the first mobile device that could display web pages almost as well as most desktop computers do (with the notable exception of its inability to play flash and many video formats). understanding the power of the ipad initially derided as “an iphone that can’t make phone calls,” the ipad’s success has been unlike anything ever seen by the electronics industry. even the dvd player, which was the previous champion at upending established markets, has been buried by the ipad frenzy. the ipad was selling at a rate of 41⁄2 million units per quarter and is already generating more revenue for apple than its entire desktop and laptop computer lines. with this information in mind, any forward-thinking web designer must explore what it means to design websites for these new mobile platforms. you can start by considering the difference between creating content and consuming all the text, video, web pages, e-books, music, and other increasingly interactive rich media that’s now available. whether you’re designing a website to be viewed in business settings on the desktop web, as traditional browsing is called, or consumed on an iphone while killing time waiting in line, remember that at the end of the line is a person. and, every member of the digital world is quickly coming to expect to find what they want, when they want it, on whichever device they want it on. designing for two screens throughout this book, you see screen shots taken on the iphone 4 and the ipad displayed side by side (refer to figure 1-5). we do this to show you how the landscape and portrait views look side by side. to help you quickly identify designs on an iphone, such as the one shown on the left in figure 1-6, from designs on the ipad, such as the one shown on the right of the figure, we used photoshop to insert each screen shot into a frame so that you can see the surrounding edges of each device. figure 1-6: for the best results, create different designs for the iphone and ipad screens. we’ve been careful to preserve the integrity of our screen shots: the proportions and amount of the design you can see in the display area are true to life, though we don’t always display the iphone and ipad to scale when we put them next to each other. in most figures where both devices appear, the iphone is larger than actual size in comparison to the ipad. we do this not because we favor the iphone (although it is cute), but, rather, because we believe that all devices should have an equal opportunity to look good: if we printed the iphone screen to scale next to the ipad screen, the iphone screen would be too small for you to see clearly the details of the designs. reaching android users, too although the iphone has been the subject of all the hype of the past few years, droid phones, which run on the google android operating system, started outselling iphones in the first quarter of 2010 and are likely to continue to do so. many predict that google could beat apple with the android operating system on the mobile platform in much the same way that microsoft won on the desktop. because android phones can be created by many companies (not by just one, such as apple making the iphone), they’re generally cheaper and available on more networks. a growing list of phones and tablet devices run on the android operating system, and more are being released all the time. the good news is that most of what’s possible when it comes to web design for safari (the ios on the iphone and ipad) will work just fine on devices that run android. consider it a bonus: you aren’t simply finding out
