ResponsiveWeb Design has been a very hot topic this year, inspiring developers wholong for a “one codebase serves all” future. But critics of thetechnique have pointed out several issues that need to be addressedbefore it can scale perfectly from handheld to desktop — specifically,while HTML, CSS and JavaScript can be light enough to share across allexperiences, desktop-optimized images are often too heavy for mobileconnections, and mobile-optimized images are too low quality for desktopviewers.

Proportional image scaling in your responsive web design. Having images scale properly along with its container is a given when it comes to responsive web design. I’ve seen a few responsive web site over the last few weeks who seems to have forgotten this, which is a real shame since it is so very easy to fix this. All you need to do is give the images a percentage based max-width. A responsive web design layout will feature schemes and a layout that gracefully breaks down and reinvents itself. From a usability perspective this is a brilliant technique. Responsive design is all about creating a homogeneous experience regardless of the browser or device screen size. This is the seminal article that started off the whole responsive design movement. Responsive Web Design: What It Is and How To Use It. A nice in-depth article by Kayla Knight, explaining various responsive design techniques, including image scaling and content hiding. Also includes a showcase of responsive sites. A tale of two viewports.

Recently, we began work on a large-scale responsive design(collaborating with the incredibly talented Mr. EthanMarcotte, who notably got this whole“responsive” partystarted), inwhich we’ve set out to address this shortcoming of responsive designwith a technique that requests an appropriate image size for a givencontext without resorting to tactics like User Agent sniffing. We feelstrongly that these responsive techniques present a most practical wayforward in web development. This post documents our in-progressexperiment with “Responsive Images.”

What is this all about? #

The goal of this technique is to deliver optimized, contextual imagesizes for responsive layouts that utilize dramatically different imagesizes at different resolutions. Ideally, this approach will allowdevelopers to start with mobile-optimized images in their HTML andspecify a larger size to be used for users with larger screenresolutions — without requesting both image sizes, and without UAsniffing.

How’s it work? #

The technique consists of a few key files: rwd-images.js, rwd.gif,and some .htaccess directives. To use, just drop the .htaccess fileinto your root web directory (this requires an Apache web server, and ifyou already have an .htaccess file, you can paste its contents into yourexisting file), and reference rwd-images.js from an HTML page.

Any images that you’d like to scale and load responsively should startby referencing a mobile-friendly image size, adding a “.r” prefix to thefile extension, and reference a larger size using a HTML5 customattribute data-fullsrc (the image referenced by data-fullsrc will beused for screen resolutions greater than 480px).

As that page loads, the rwd-images.js script inserts a BASE elementinto the head of your page, directing all subsequent image, script, andstylesheet requests through a fictitious directory called'/rwd-router/'. As these requests reach the server, the .htaccess filedetermines whether the request is a responsive image or not. Itredirects responsive image requests temporarily to rwd.gif (atransparent 1px gif image), while all non-responsive image requests goto their proper destination through a URL rewrite that ignores the'/rwd-router/' segment. When the HTML finishes loading, rwd-images.jsremoves the BASE element from the DOM (resetting the base URL) and setsthe responsive image sources to either their small or large size (ifspecified), depending on whether the screen resolution is greater than480px.

We’ve found that the technique works in most modern browsers (Safari(desktop, iPhone, iPad), Chrome, Internet Explorer (8+), Opera). Thetechnique degrades gracefully in other browsers, such as IE7 and under.In those browsers, desktop users will still receive an appropriate imagesize, but the mobile image will download as well, causing slight butunfortunate overhead. As development continues, we may find a workaroundto bring full support to these browsers.
