The web has always been a balancing act…

http://www.ﬂickr.com/photos/classblog/5136926303

with many competing priorities.

http://www.ﬂickr.com/photos/tudor/4324056624/

Finding that balance is
more diﬃcult…

http://www.ﬂickr.com/photos/superfantastic/50088733/

as device diversity increases.

Responsive web design oﬀers us

for a sensible way to deal with device diversity.

And yet the one question I frequently ask myself is…

Can a one size fits all solution…

Everyone hates slow loading websites, and a new survey
highlights just how damaging a slow site can be to the user
experience.
The study by Brand Perfect found that two thirds of UK
consumers (67%) cite slow loading times as the main reason
they would abandon an online purchase.
It’s a topic we’ve looked at in more detail in our post 'Site
speed: case studies, tips and tools for improving your conversion rate', with stats showing that
slow loading websites are losing businesses up to £1.73bn a year.

Keep basic styles outside of media queries.

“

The absence of support for media queries is in fact
the first media query.
—Bryan Rieger, Yiibu

IE8 and below don’t
support media queries.

What do you see if your browser doesn’t support media queries?

Desktop First Responsive Web Design =

Mobile First Responsive Web Design =

IE conditional comments
<link rel="stylesheet" type="text/css" href="taps.css" />
<link rel="stylesheet" type="text/css" href="layout.css" media="all and
(min-width: 481px)">


The conditional comment repeats the line above it
ensuring desktop IE sees our layout.css file.

IE conditional comments
<link rel="stylesheet" type="text/css" href="taps.css" />

The conditional comment repeats the line above it
ensuring desktop IE sees our layout.css file.

or use Respond.js
(a media query polyfill for IE)

#2
Keep CSS images
in their place

Images with display:none are still downloaded

Image override with a media query

}
}


#3

Conditionally load JS based on
screen size and capabilities

http://www.ﬂickr.com/photos/lyza/7382255242/

Hiding content with display:none does not
prevent it from downloading.
<iframe id="map" width="300" height="300" frameborder="0" scrolling="no"
marginheight="0" marginwidth="0" src="http://maps.google.com..."></iframe>

This single iframe causes 47 files to be downloaded!

Extremely long URL abbreviated

.
.
.

are many more rules
There
in the css file.

#map {display:none;}
}

The iframe has an id of map. This rule hides
the Google Maps iframe by setting the
display to none.

In JS, use
matchMedia()
or a polyfill for
it to test a
media query

https://github.com/paulirish/matchMedia.js

AJAX Include Pattern
Use AJAX to bring more content into the page as the viewport width gets bigger

<a
href="articles/latest/"

data-‐append="articles/latest/fragment"

data-‐media="(min-‐width:
30em)">

Latest

How do you maintain the aspect ratio of video?
• This is mostly a problem if you’re embedding video from a third
party site. If you are using your own video, it is not usually an
issue.
• For third party video, FitVid.js is a good place to start.
• For your own video, the only trick is making sure you’re not
changing the proportions of the video element as the page
resizes.

How do you send the right resolution and quality?

It’s three years later. Let’s revisit the
my original question.

Can a one size fits all solution…

http://www.ﬂickr.com/photos/theyoungthousands/4025421438

compete with
a tailored experience?
http://www.ﬂickr.com/photos/fronx/2862975043

http://www.flickr.com/photos/haddadi/5971508861

Or will it always be TOO BIG?

Unlikely responsive design will
ever be as fast as something
crafted specifically for a device.

http://www.ﬂickr.com/photos/quarenta/3256329577

But web design is
a balancing act.

http://www.ﬂickr.com/photos/kalexanderson/6266452817

And performance is
just one factor.

For most projects, responsive
design can be fast enough to
make sense…
