Responsive Web Design: What It Is And How To Use It
Almost every new client these days wants a mobile version
of their website. It’s practically essential after all: one design for the
BlackBerry, another for the iPhone, the iPad, netbook, Kindle — and all screen
resolutions must be compatible, too. In the next five years, we’ll likely need
to design for a number of additional inventions. When will the madness stop? It
won’t, of course.
Responsive Web design is the approach that suggests that
design and development should respond to the user’s behavior and environment
based on screen size, platform and orientation. The practice consists of a mix
of flexible grids and layouts, images and an intelligent use of CSS media
queries. As the user switches from their laptop to iPad, the website should
automatically switch to accommodate for resolution, image size and scripting
abilities. In other words, the website should have the technology to
automatically respond to the user’s preferences. This would eliminate the need
for a different design and development phase for each new gadget on the market.
But responsive Web design is not only about adjustable
screen resolutions and automatically resizable images, but rather about a whole
new way of thinking about design. Let’s talk about all of these features, plus
additional ideas in the making.
Adjusting Screen Resolution
With more devices come varying screen resolutions,
definitions and orientations. New devices with new screen sizes are being
developed every day, and each of these devices may be able to handle variations
in size, functionality and even color. Some are in landscape, others in
portrait, still others even completely square. As we know from the rising
popularity of the iPhone, iPad and advanced smartphones, many new devices are
able to switch from portrait to landscape at the user’s whim. How is one to
design for these situations?
PART OF THE SOLUTION: FLEXIBLE EVERYTHING
A few years ago, when flexible layouts were almost a
“luxury” for websites, the only things that were flexible in a design were the
layout columns (structural elements) and the text. Images could easily break
layouts, and even flexible structural elements broke a layout’s form when
pushed enough. Flexible designs weren’t really that flexible; they could give
or take a few hundred pixels, but they often couldn’t adjust from a large
computer screen to a netbook.
Flexible Images
One major problem that needs to be solved with responsive
Web design is working with images. There are a number of techniques to resize
images proportionately, and many are easily done.
FILAMENT GROUP’S RESPONSIVE IMAGES
This technique, presented by the Filament Group, takes
this issue into consideration and not only resizes images proportionately, but
shrinks image resolution on smaller devices, so very large images don’t waste
space unnecessarily on small screens.
Custom Layout Structure
For extreme size changes, we may want to change the
layout altogether, either through a separate style sheet or, more efficiently,
through a CSS media query. This does not have to be troublesome; most of the
styles can remain the same, while specific style sheets can inherit these
styles and move elements around with floats, widths, heights and so on.
