that suggests that design and development
should respond to the user’s behavior and
environment based on screen size,
platform, and orientation.

Heuristics of
Responsive Web Design
1. Flexible Everything
2. Design for Mobile First
3. Design for Progressive Enhancement
&/or Graceful Degradation
4. Optimize Content Rather Than Support
Flexible Everything
• Fluid or Liquid Layouts
• Proportionally Scaled Images
• Media Queries
Flexible Everything –
Flexible Layout
• Use percents and ems
• Don’t use finite values like pixels
• How do you convert? It’s easy:
.figure {width: 20.833%; /* 200px / 960px */ }
.headerText {font-size: 0.75em; /* 12px / 16px */ }
Flexible Everything Proportionally Scaled
Images
• Hiding and Revealing Portions of Images
• Deliver different images depending on device
• Foreground Images That Scale With the Layout

Flexible Everything –
Media Queries
• They’ve been around since CSS 2.1
• You’ve already used them
<link rel="stylesheet" type="text/css" href=“screen.css" media="screen" />
<link rel="stylesheet" type="text/css" href="print.css" media="print" />
• When CSS3 came out the W3C extended media queries
Flexible Everything –
Media Queries
@media screen and (max-width: 420px) {
.figure{
margin-right: 3.317535545023696682%;
width: 48.341232227488151658%;
}
Design for Mobile First
• Multiple screen sizes & densities
• Performance optimization
• Device capabilities
Design for Mobile First
• Consider Screen Size
• Know your users
• Focus on core actions
• Use scalable design
Design for Mobile First
Netbooks: 9" diagonal display, screen resolution of 1024 x 600 pixels, pixel
density approximately 133 ppi
iPhone: 3.6" diagonal display, screen resolution of 320 x 480 pixels, pixel
density of 160 ppi
Nokia E60: 2.2" diagonal display, screen resolution of 416 x352 pixels, pixel
density of over 240 ppi

Design for Progressive
Enhancement
Progressive enhancement is an approach to web
development that aims to deliver the best possible
experience to the widest possible audience
Design for Progressive Enhancement
& Graceful Degradation
• basic content should be accessible to all browsers
• basic functionality should be accessible to all browsers
• sparse, semantic markup contains all content
• enhanced layout is provided by externally linked CSS
• enhanced behavior is provided by unobtrusive, externally linked JavaScript
• end user browser preferences are respected
