Der klassische Ansatz • 2 Webseiten • Desktop-Seite • speziell
auf mobile Geräte angepasste mobile Seite • Redirect auf m. * je nach User-Agent

Der responsive Ansatz Eine Webseite, die sich automatisch dem Device
(Screen-Größe) anpasst
Beispiel: The Boston Globe • Full „fluid“ responsive • fluid
innerhalb der Breakpoints • funktioniert gut bei textlastigen Seiten http://upstatement.com/blog/2012/01/how-to-approach-a-responsive-design/
None
Beispiel: trivago • Sprungstufen-basiertes Layout • adaptives Layout • innerhalb
der Breakpoints fixe Darstellung • ohne kompletten Relaunch möglich
Desktop, iMac, Laptop
Landscape Tablet, Netbook
IPad, Tablets
Filterleiste einblendbar
Smartphone
Eine Definition Responsive web design isn’t your site working on
phones and tablets. It’s about your site working everywhere. https://twitter.com/ScottKellum

Zutaten nach dem Rezept von Ethan Marcotte ! •
Relative Maße • Ein flexibles gridbasiertes Layout • Flexible Images und Medien • Media Queries
EMs nutzen • skalierbare Einheit • 1em = aktuelle Fontgröße
• 2em = doppelte Fontgröße body {font-size: 100%} body {font-size: 150%} font-size: 12px Textbeispiel Textbeispiel font-size: 1em Textbeispiel Textbeispiel
None
Sieh das mal relativ! ! ! target / context =
result Erstellung relativer Maße: Fonts / Grids
Flexible Grids / Maße 960px 200px target / context =
result (200 / 960) * 100 = 20,83%
Flexible / fluid media Fluid Images: max-width http://clagnut.com/sandbox/imagetest/ img, embed,
object, video { max-width: 100%; }
Flexible / fluid media

Media Types CSS 2.1 Media Types ! <link rel="stylesheet" type="text/css"
href="core.css" media="screen" /> ! <link rel="stylesheet" type="text/css" href="print.css" media="print" />
Media Queries CSS3 Nicht nur Device Typen sondern Devicegerätetypische Eigenschaften
abfragen ! <link rel="stylesheet" type="text/css" href="style.css" media="screen and (device-width: 480px)" />
Media Queries Mehrere Eigenschaften in einer Query ! @media screen
and (max-device-width: 480px) and (resolution: 192dpi) { .column { float: none; } }
Viewport https://www.flickr.com/photos/mendhak/2252824493
Viewport-Metatag <meta content="width=device-width, initial-scale=1.0" name="viewport" /> Mit Viewport-Metatag viewport-width =
device-width ! Ohne Viewport-Metatag Default-Canvas ~980px http://bkaprt.com/rwd/29

Mobile Strategie You May Be Losing Users If Responsive
Web Design Is Your Only Mobile Strategy http://www.smashingmagazine.com/2014/07/22/responsive-web-design-should-not-be-your-only-mobile-strategy/
Page Sizes 72% of responsive websites deliver the same number
of bytes regardless of screen size, even on slow mobile network connections. http://www.guypo.com/uncategorized/real-world-rwd-performance-take-2/
