9. Definition
Responsive Web Design (RWD) is an approach to web design
in which a site is crafted to provide an optimal viewing
experience—easy reading and navigation with a minimum of
resizing, panning, and scrolling—across a wide range of devices
(from desktop computer monitors to mobile phones).
In short: the site should be usable on all devices and should feel
optimized for all devices.

10. How to RWD?
Media queries!
Media queries allow the page to use different CSS styles based
on device capabilities.
For RWD, we will look at browser width.

11. Media queries code structure
@media screen and (max-width: 767px) {
…
}
@media screen and (min-width: 768px) and (max-width: 979px) {
…
}
@media screen and (min-width: 980px) {
…
}

12. RWD and Images
1. Use background images when possible.
2. How to create flexible or fluid images
3. Lazy load images for better page performance

13. Background Image Example: logo
<div class="df-logo">
<a href="#">AppExchange</a>
</div>
.df-logo a { /* S: Phone */
display: block; @media (max-width: 767px) {
text-indent: -9999px; .df-logo a { display: none; }
width: 223px; .df-logo {
height: 47px; width: 100px;
background: url(appex-logo.png) no-repeat 0 0; height: 21px;
} margin-left: -50px;
position: absolute;
top: 5px;
left: 50%;
background: url(appex-logo-small.png) no-repeat 0 0;
}
}

14. How to Create Flexible or Fluid Images
<div class="df-tile"> .df-tile {
<div class="tile-content"> width: 240px;
<div class="tile-img tile-img-brand"> height: 200px;
<img src="tile-01-280.png" /> }
</div>
</div> .df-tile .tile-img-brand {
</div> padding: 10px;
}
.df-tile img {
border: 1px solid #999;
max-width: 100%;
width: auto; /* IE */
height: auto; /* IE */
}

15. Lazy Load Images for Better Page Performance
<div class="tile-img tile-img-brand">
<img src="p.gif" data-src="tile-01-280.png" class="desktop-img" />
</div>

16. Lazy Load Images for Better Page Performance
<span id="phone-test"></span>
<span id="small-test"></span> /* S: Phone */
<span id="large-test"></span> @media screen and (max-width: 767px) {
#phone-test { display: block; }
}
#phone-test, #small-test, #large-test {
width: 1px; /* M: Portrait tablet */
height: 1px; @media screen and (min-width: 768px) and (max-width: 979px) {
display: none; #small-test { display: block; }
} }
/* XL: Desktop */
@media screen and (min-width: 1220px) {
#large-test { display: block; }
}

17. Lazy Load Images for Better Page Performance
getCurrentSiteState = function() {
var state = 'medium';
if (jQuery('#phone-test').css('display') === 'block') { state = 'phone'; }
else if (jQuery('#small-test').css('display') === 'block') { state = 'small'; }
else if (jQuery('#large-test').css('display') === 'block') { state = 'large'; }
return state;
};

18. Lazy Load Images for Better Page Performance
<div class="tile-img tile-img-brand">
<img src="p.gif" data-src="tile-01-280.png" class="desktop-img" />
</div>
jQuery(document).ready(function() {
loadDesktopImages();
});
loadDesktopImages = function() {
if (getCurrentSiteState() !== 'phone') {
jQuery('img.desktop-img').each(function() {
jQuery(this).attr('src’, jQuery(this).attr('data-src'));
});
}
};
