Approaches to Responsive Design & DevelopmentJanuary 21, 2013
What is Responsive Design?• An approach to web design in
which a site is crafted to provide an optimal viewing experience – easy reading and navigation with a minimum of resizing, panning, and scrolling – across a wide range of devices (Wikipedia)
• Ethan Marcotte, A List Apart, Responsive Web Design (May 25, 2010)
• No longer a ‘luxury’
Elements of Responsive Design• Fluid Grids & Fluid Layouts• Media Queries • Flexible Images/Media
• Responsive Menus• Flexible type
Fluid Layouts• Benefits vs. fixed-width layout; drawbacks• Target / Context = Result
Fixed-Width (based on pixels) Fluid Layout (based on %’s)
Fluid Grids• Typically 12 or 16 columns with column width and gutters
based on %’s• Example:
Using Fluid Grids• 1140gs – cssgrid.net (PSD template included)• Foundation by Zurb (framework)• Twitter Bootstrap (framework)• Use 12/16 column PSD template when creating mockup
Media Queries• Placed in stylesheet (can also use Javascript detection)• Looks at the capability of the device and checks for:• Width & Height of browser window• Orientation• Resolution

Media Query Example
@media only screen and (min-device-width : 320px) and (max-device-width : 480px) {
#primary-nav {display:none;}#responsive-nav {display:block;}
}
• Example: RoomTemp• Concept of ‘breakpoints’
Media Query Breakpoints• Browser widths that have a media query declaration to change
the layout once the browser is within the declared range• 320 px — Mobile portrait• 480 px — Mobile landscape• 600 px — Small tablet• 768 px — Tablet portrait• 1024 px — Tablet landscape/Netbook• 1280 px & greater — Desktop
Flexible Images & Media
img, embed, iframe {Max-width:100%;Height:auto;}• http://css-tricks.com/video-source-by-screen-size/ -
Different videos depending on screen size and device• http://retinajs.com/ - Retina Images
Responsive Menus• Full Horizontal• Select Box (ex. RoomTemp)• Custom Dropdown (ex. Daystar)• Off Canvas
• http://css-tricks.com/responsive-menu-concepts/
Flexible Typography• Set body to font-size:100% / 1em (16px)• Base all fonts relative to the base font size, so a 32px H1 would
be 2em (32 / 16 = 2)• This makes it easy to adjust all typography with a single media
query, changing the body font-size up or down• PxtoEm.com• CSS3 rems (based off HTML element, no nesting)
Responsive Frameworks• Based around a fluid grid (except Skeleton); some contain user
interface elements and additional features• Skeleton • Twitter Bootstrap• Zurb Foundation • 1140 CSS Grid
Advantages of Frameworks• Basic media queries & responsiveness done for you• Cross-browser tested• Rapid protoyping; grid template provided for designing• Drawbacks: learning curve, lots of markup, can be tough to
create highly custom designs
Helpful Plugins• CSS3-Mediaqueries.js (support for media queries on IE8 and
below)• Retina.js (serve up high res images)• Fittext.js (scalable headlines)• FlexSlider (responsive slider)• FitVids.js (fluid video embeds)
Hacking Responsive Wordpress Themes
• Inspect the behavior of the site• Look at the media queries• Determine if they are using a framework…learn how to
incorporate that• Example: Teamate.us
