responsive web
design
ü Thinking of the user’s needs instead of ours.
ü Adapt to various device capabilities instead of configurations.
ü Help future-proof our sites.

that’s the way
1. A flexible, grid-based layout,
2. Flexible images and media,
3. Media queries.
the secret sauce
flexible grid-based
layout
§ Non-responsive sites are no fun.
§ Fixed-width sites are not the best experiences.
§ Not thinking about new web platforms.
what’s the problem?

target context result
* you can use rem – context will be root
h1 { font-size: 24px;}
24 / 16 = 1.5h1 { font-size: 1.5em;}
h1 a { font-size: 11px;}
11 / 24 = 0.45833333+h1 a { font-size: 0.458+;}

.main .other.blog
body
#page { width: 960px;}
.blog { width: 900px;}
.blog .main { width: 566px;}
.blog .other { width: 331px;}
#page { width: 960/1024;}
.blog { width: 900/960;}
.blog .main { width: 566/900;}
.blog .other { width: 331/900;}
#page { width: 93.75%;}
.blog { /* 900/960 */ width: 93.75%;}
.blog .main { width: 62.88+%;}
.blog .other { width: 36.77+%;}
flexible images
& media
/* Works on other media like <video> */img { max-width: 100%;}
simple solution
<picture> <source media="(min-width: 40em)” srcset="big-hd.jpg"> <source srcset="small-hd.jpg"> <img src="fallback.jpg" alt=”The image"></picture>
picture element
media queries
§ We could define media types: screen and print.
§ But not easily respond to the user’s display.
§ Lots of grunt work.
§ Didn’t spend much time thinking about mobile devices.
not so long ago…
The CSS3 Media Queries Module specifies methods to enable web developers to scope a style
sheet to a set of precise device capabilities.
css media queries
@media screen and (max-width: 600px) {
body {
font-size: 80%;
}
}
that simple
@media screen and (min-width:320px) and (max-width:480px) { /* add your code here */ }
@media not print and (max-width:600px) { /* add your code here */ }
@media screen (x) and (y), print (a) and (b) { /* add your code here */ }
let’s get funky
@import url(mq.css) only screen and (max-width:600px)
<link rel=“stylesheet”media=“only screen and (max-width:800px)” href=“mq.css”>

§ Is it best that all sites are responsive?
§ Do we start with mobile-first?
§ Do we go Adaptive Web Design instead?
§ Do we need or want to do visual comps for every device?
§ Don’t dismiss mobile as walking and looking something up.
