RESPONSIVE ENHANCEMENT
I WORK AT SWWWEET.COM HI, I’M @HTMLBOY
I WORK AT SWWWEET.COM HI, I’M @HTMLBOY
I’m a web designer & front-end dev
I’m a web designer & front-end dev DISSAPOINTED
TOP 10 WEB DESIGN MYTHS
the Future is high-speed connections everywhere MYTH #1
flickr.com/photos/potjie/543400371
MYTH #2 Mobile = Stress Desktop = Relax
flickr.com/photos/shareski/5453209957
MYTH #3 We can’t give the full content to mobile
devices
3 or 4 Ferraris are sold every month on eBay's
mobile apps.” “ globalmoxie.com/blog/mobile-commerce-belly-flop.shtml
MYTH #4 Superhardware awesomeness!
flickr.com/photos/alien-paranoia/4941130941
MYTH #5 Auto-updated high-tech browsers by default
flickr.com/photos/mattimattila/5703851562
MYTH #6 Nobody browses without JS (and we have <noscript>)
We don't have any non-JavaScript users” No, all your users
are non-JS while they're downloading your JS Jake Archibald “
MYTH #7 We control the content with JS and CSS
None
MYTH #8 We should only care about popular devices
None
MYTH #9 Everybody browses full-screen
None
MYTH #10 Big = mouse Small = touch
None
CHANGING THE WAY WE WORK
Build always with a FALLBACK
HTML FALLBACKS <canvas> <span>Fallback content</span> </canvas>
.canvas{ border:10px solid grey; border-color: rgba(0,0,0,.5); } CSS FALLBACKS
Detect SUPPORT for new & shiny properties
modernizr.com MODERNIZR .no-cssgradients .button{ background: url(gradient.png); }
bit.ly/css-supports @SUPPORTS @supports (display:flex) { section { display: flex; }
}
RESPONSIVE web design
None
None
None
FLEXIBLE GRIDS aside{ width: 38%; margin-left: 2%; float: right; }
FLEXIBLE IMAGES .img-container img{ max-width:100%; }
@media all and (max-width:400px){ .aside{ width:100%; margin-left:0; float:left; } }
MEDIA QUERIES
MOBILE FIRST
One-column Small assets Clear hierarchy
<!-- [if lte IE 8]> <link rel=”stylesheet” href=”ie8.css”> <![endif]--> IE8
!= MEDIA QUERIES
or use respond.js github.com/scottjehl/Respond
We are reaching the BREAKING POINT
We can’t use the same CSS & JS everywhere
RESPONSIVE ENHANCEMENT introducing...
Instead of just using progressive enhancement to throw in some
rounded corners[...], we can apply the same thinking to layout.” Jeremy Keith “
START WITH THE CONTENT Text Images Links
LEGACY LAYOUT Let’s call it the
Consider the LAYOUT as an ENHANCEMENT
HIDING STYLES @media all and (min-width:1px){ /*styles for browsers with
media query support*/ }
FIX THE DESIGN IF IT BREAKS Stop being obsessed with
“popular devices”
USE EM-BASED MEDIA QUERIES Be prepared to be zoomed. Play
nice with smart TVs
Consider JAVASCRIPT as an ENHANCEMENT
NON-JS BY DEFAULT
CONTENT FIRST So basically...
ENHANCE IT WITH LAYOUT, JAVASCRIPT & DECORATION
Build for THE FUTURE
Build for THE FUTURE and for THE PAST
