Responsive web design

From Wikipedia:

“[RWD] is a Web design approach aimed at crafting sites toprovide an optimal viewing experience—easy reading andnavigation with a minimum of resizing, panning, andscrolling—across a wide range of devices (from mobile phones todesktop computer monitors).”

Uses principles:Proportion-based grids: Page element sizing to be in relative unitslike percentages, rather than absolute units (e.g., pixels).Flexible images: sized in relative units to containing element.CSS3 media queries (extension of @media rule): CSS style rulesbased on characteristics of the device (e.g., browser width).


http://en.wikipedia.org/wiki/Responsive_web_design

Responsive CSS framework (1): Bootstrap


http://getbootstrap.com/

Responsive CSS framework (2): Foundation

Responsive CSS usage: Bootstrap example

In the HTML head, include CSS, e.g.:

<link rel="stylesheet" href="// netdna.bootstrapcdn.com/

bootstrap /3.1.1/ css/bootstrap.min.css">

Use their CSS templates, e.g., specify viewport:

<meta name="viewport" content="width=device -width , initial -scale=1">

Use components (e.g., icons, buttons, drop-down menus, etc.)Also has Javascript (jQuery plugins – will talk about this later)Your website will look clean (example)

Why use responsive web and not mobile apps?

Responsive web:One solution for allServer+client solution can be faster than mobile app.iOS and Android have peculiarities (licensing, language, versions,compatibility)

Mobile apps:Usually faster to startResident on mobile device and can be activated based on time, orevent (e.g., GPS location)Mobile markets make it easy to advertise
