7. PATTERNS Adaptive Systems for Multiple Devices HD Live 4th Nov 2010 THAT ARE UNIQUELY OURS
8. The screen brings with it different kinds of challenges for visual design, some of which occur exclusively in interactive media. It’s unrealistic to think our old methods can fill in all the gaps, but new interaction patterns and visual languages emerge everyday. These are the building blocks for our new design principles. JASON SANTA MARIA, 2008

15. ADAPTIVE Adaptive Systems for Multiple Devices HD Live 4th Nov 2010 LAYOUTS
16. • Use one set of files for the website • Manipulate the resolution, viewport, and orientation • Deliver 100% of the content • Or, deliver the device-relevant content • Surprise. Delight. Be creative!
17. The ability to alter the presentation of a website without altering its structure should have opened up the floodgates of design creativity. JEREMY KEITH, 2006
25. RESPONSIVE Adaptive Systems for Multiple Devices HD Live 4th Nov 2010 WEB DESIGN

27. Ethan states that a responsive design is composed of three distinct parts: 1. Flexible grid. 2. Flexible images. 3. Media queries.
32. FLEXIBLE GRID Adaptive Systems for Multiple Devices HD Live 4th Nov 2010 RESPONSIVE INGREDIENT # 1
34. • Relative measurements • Percentages and ems • min-width and max-width • Maths!

37. FLEXIBLE IMAGES Adaptive Systems for Multiple Devices HD Live 4th Nov 2010 RESPONSIVE INGREDIENT # 2
38. img { width:380px; height:auto; } img { height:auto; max-width:100%; } For a Windows fix, see http://unstoppablerobotninja.com/entry/fluid-images
39. MEDIA QUERIES Adaptive Systems for Multiple Devices HD Live 4th Nov 2010 RESPONSIVE INGREDIENT # 3
40. A media query consists of a media type and zero or more expressions that check for the conditions of particular media features. Among the media features that can be used in media queries are ‘width’, ‘height’, and ‘color’. By using media queries, presentations can be tailored to a specific range of output devices without changing the content itself. http://www.w3.org/TR/css3-mediaqueries/
41. @media  (max-­‐device-­‐width:480px)  and   (orientation:portrait)  {  }
42. • nth-child for flow of images • Proportional leading • Change anything you want!
43. CASE STUDY Adaptive Systems for Multiple Devices HD Live 4th Nov 2010 COLLY.COM
45. <meta  name="viewport"   content="width=device-­‐width"  />
46. @media  (min-­‐device-­‐width:1024px)  and  (max-­‐ width:989px),  screen  and  (max-­‐device-­‐ width:480px),  (max-­‐device-­‐width:480px)  and   (orientation:landscape),  (min-­‐device-­‐ width:481px)  and  (orientation:portrait)  { div#page  {  width:468px;  }  } 1. Devices with a minimum width of 1,024 pixels and windows with a maximum width of 989 pixels. 2. Screens that have a maximum device width of 480 pixels. 3. Devices with a maximum width of 480 pixels and are also in landscape orientation. 4.Devices with a minimum width of 481 pixels and are also in portrait orientation. 5. When one of the above criteria are met, resize the page division to 468 pixels.
47. @media  (min-­‐device-­‐width:1024px)  and  (max-­‐ width:509px),  (max-­‐device-­‐width:480px)  and   (orientation:portrait)  { div#page  {  width:306px;} With these two queries, the page division shrinks to 306 pixels wide when viewed with: 1. devices with a minimum width of 1,024 pixels and windows with a maximum width of 509 pixels. 2. devices with a maximum width of 480 pixels which are also in landscape orientation.
