    Summary: Testing phones, tablets, or other mobile devices with real users is similar to studies with regular computers, but requires special consideration for recording equipment, room setup, and even the test participants.

mobile media queries css responsivedesign mediaqueries webdesign interaction

  • The photographs come to life when you hover over them.
  • There are some good uses of CSS media queries. If you’re building a discrete web application where you have more control and can make sure that the desktop web isn’t bloated, it can make sense.
  • Two methods that appear to work are: Setting the parent of an element with a background image to display:none.3 Using media query min-width declaration to only specify a minimum browser width for the desktop image and a max-width for the mobile image does result in only the mobile image being downloaded in Mobile Safari.5 These two options mean that using CSS media queries isn’t completely impossible, but using the parent element to hide images and changing existing desktop CSS to add min-width declarations are significant changes to existing CSS. It isn’t going to be as simple as adding a CSS media query for mobile and calling your job done.

  • If you send the same HTML and Javascript to the mobile user that you do for the desktop user, even if you format it to fit their screen, you’re likely missing opportunities to provide a great mobile experience based on the capabilities of the device and the context of the mobile user.
  • But the core mechanism used to accomplish them, CSS media queries, isn’t up to the task when it comes to mobile development.
  • In both cases, it showed the image files are downloaded despite the fact that the media query has set them to display:none. This means that the iPhone downloads an extra 172K for photos that the user will never see.
  • More desktop web sites that take advantage of fluid grids and CSS media queries to optimize for the multiple sizes of desktop screens. Media queries still make sense for desktop designs.
  • Also, Ros Hodgekiss from Campaign Monitor wrote an exceptional article on how you can use media queries in html email to provide a mobile optimized layout. This is perhaps the ideal use case because when you send html email, you have no choice but to send a single html document regardless of what device the recipient will be using.
  • Does your desktop web home page use geolocation lookups? Probably not. Should your mobile site home page? Quite possibly.
  • Ignoring the Mobile Context The promise of CSS media queries is that you can take your existing desktop web site html and add this additional presentation layer for mobile. Doing so ignores the fact that a mobile user may have very different needs than a desktop user.

mobile touch icons ios apple iphone webdesign html

  • Say adiós to the boatload of proprietary <link rel="apple-touch-icon"> elements on every single HTML page.
  • Just create different versions of the icon, use the correct file names and place them in the root.
  • So, what do we need? apple-touch-icon-57x57-precomposed.png or apple-touch-icon-57x57.png for non-Retina iPhone and iPod Touch; apple-touch-icon-72x72-precomposed.png or apple-touch-icon-72x72.png for the first- and second-generation iPad; apple-touch-icon-114x114-precomposed.png or apple-touch-icon-114x114.png for iPhone 4+ (with Retina Display); apple-touch-icon-144x144-precomposed.png or apple-touch-icon-144x144.png for iPad 3+ (with Retina Display); apple-touch-icon-precomposed.png and apple-touch-icon.png as a fallback for everything else (possibly including non-Apple devices).
  • ...5 more annotations...
  • It’s a good idea to include both apple-touch-icon.png and apple-touch-icon-precomposed.png for maximum compatibility: iOS 1 and BlackBerry OS6 don’t support precomposed icons. (Note that Android 2.1 only supports precomposed icons.)
  • Sadly, the no-HTML approach doesn’t work on the native Android browser (tested in 2.3 Gingerbread, 3 Honeycomb, 4.1 Jelly Bean), although I’ve had reports saying it does work in and 4.2 Jelly Bean’s default browser.
  • For web pages that don’t specify a custom touch icon, a thumbnail screenshot of the page is used instead. Android has a default icon, and some systems fall back to the favicon if it’s available.
  • I’d recommend to always use precomposed icons. It gives you full control over your icon, and it’s the only kind of icon Android 2.1 supports.
  • This way, older iOS versions download the smallest icon instead of the largest one. So, instead of forcing the largest icon to all devices unless they support the sizes attribute (iOS 4.2+), we now serve the smallest icon unless @sizes is supported. In other words, we’re now using progressive enhancement instead of graceful degradation :) When in doubt, always use this snippet. With support for nearly all iOS versions and devices, and as many different Android versions as possible, it’s the most robust way to add touch icons to your site.

  • There's no need to declare this "the year of mobile." If anything, last year was the year of mobile in terms of the growth in both mobile usage and the availability of mobile sites and apps. Now, however, it's time to redesign your mobile site, because your existing version is probably far below users' growing expectations for user experience quality.
  • In addition to user testing, we also conducted 2 rounds of diary studies to discover how people use mobile devices in their everyday life. One diary study was in the U.S.; the other included participants from Australia, The Netherlands, Romania, Singapore, the U.K., and the U.S. In total, 27 people participated in the diary studies, providing us data about 172 person-days of mobile activities. Again, participants had a wide range of jobs, from bookkeeper to football coach.
  • It's interesting to consider the difference between mouse-driven desktop design and gesture-driven touchscreen design here. Desktop websites have a strong guideline to avoid horizontal scrolling. But for touch-screens, horizontal swipes are often fine. Indeed, mobile-device users typically expect to horizontally swipe their way through a carousel.

    Future for HealthKit is great if Apple can pull it off. Letting different apps and devices talk to each other essentially makes your iPhone center of your lifestyle.
