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

10.
the secret sauce
1. A flexible, grid-based layout,
2. Flexible images and media,
3. Media queries.

Flexible
Layout
Grid-based

what’s the problem?
§ Non-responsive sites are no fun.
§ Fixed-width sites are not the best experiences.
§ Not thinking about new web platforms.

what about the grid?

#page {

}
.blog {
width: 900px;
}
.blog .main {
width: 566px;
}
.blog .other {
width: 331px;

.blog {

.blog .main {

#page {

a simple solution
/* Works on other media like <video> */
img {
max-width: 100%;
}

Media
Queries

22.
not so long ago…
§ 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.

23.
CSS Media Queries
The CSS3 Media Queries Module specifies methods to enable web
developers to scope a style sheet to a set of precise device
capabilities.

24.
media queries at work
@media screen and (max-width: 600px) {
body {
font-size: 80%;
}
}

25.
let’s get funky
@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 */ }

26.
want more?
@import url(mq.css) only screen
and (max-width:600px)
<link rel=“stylesheet”
media=“only screen and (max-width:800px)”
href=“mq.css”>

27.
media properties
• min/max-width
• min/max-height
• device-width
• device-height
• orientation
• aspect-ratio
• device-aspect-ratio
• color
• color-index
• monochrome
• resolution

in the end
§ 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.
