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.

87. http://bradfrostweb.com/blog/web/mobile-first-responsive-web-design/ Graceful degradation Progressive Enhancement Mobile First Responsive Web Design is a technical approach for responsive designs.
88. /* Wider viewports/higher resolutions (e.g. desktop) */ @media screen and (min-width:481px) { [Desktop layout rules here] } /* Mobile/lower-resolution devices */ @media screen and (max-width:480px) { [Mobile layout rules here] } Move the mobile media query block above the desktop media query. By doing this, we’re making sure the cascading effect of CSS is consistent with our mobile first progressive enhancement approach.
89. Reorder media queries so cascade goes from small to large screens /* Wider viewports/higher resolutions (e.g. desktop) */ @media screen and (min-width:481px) { [Desktop layout rules here] } /* Mobile/lower-resolution devices */ @media screen and (max-width:480px) { [Mobile layout rules here] } Move the mobile media query block above the desktop media query. By doing this, we’re making sure the cascading effect of CSS is consistent with our mobile first progressive enhancement approach. Keep basic styles outside of media queries.
90. The absence of support for media queries is in fact the rst media query. —Bryan Rieger “
92. IE8 and below don’t support media queries.
93. Desktop First Responsive Web Design = Desktop Fallback Mobile First Responsive Web Design = Mobile Fallback What do you see if your browser doesn’t support media queries?
94. <link rel="stylesheet" type="text/css" href="taps.css" /> <link rel="stylesheet" type="text/css" href="layout.css" media="all and (min-width: 481px)"> <!--[if (lt IE 9)&(!IEMobile)]> <link rel="stylesheet" type="text/css" href="layout.css" media="all" /> <![endif]--> The conditional comment repeats the line above it ensuring desktop IE sees our layout.css file.
95. <link rel="stylesheet" type="text/css" href="taps.css" /> <link rel="stylesheet" type="text/css" href="layout.css" media="all and (min-width: 481px)"> <!--[if (lt IE 9)&(!IEMobile)]> <link rel="stylesheet" type="text/css" href="layout.css" media="all" /> <![endif]--> The conditional comment repeats the line above it ensuring desktop IE sees our layout.css file. or use Respond.js (a media query poly ll for IE)
96. Keep CSS images in their place #2
97. The taps.jpg file is 440.7K making it the largest file on the page. @media screen and (max-width:480px) { [Other CSS rules are here] .header {display:none;} }
98. The taps.jpg file is 440.7K making it the largest file on the page. @media screen and (max-width:480px) { [Other CSS rules are here] .header {display:none;} } Images with display:none are still downloaded
99. http://timkadlec.com/2012/04/media-query-asset-downloading-results/
100. Images scoped within media queries <div  id="test5"></div> @media  all  and  (min-­‐width:  601px)  {        #test5  {                background-­‐image:url('images/test5-­‐desktop.png');                width:200px;                height:75px;        } } @media  all  and  (max-­‐width:  600px)  {        #test5  {                background-­‐image:url('images/test5-­‐mobile.png');                width:200px;                height:75px;        } } http://timkadlec.com/2012/04/media-query-asset-downloading-results/
101. display:none on parent element http://timkadlec.com/2012/04/media-query-asset-downloading-results/ <div  id="test3">        <div></div> </div> #test3  div  {        background-­‐image:url('images/test3.png');        width:200px;        height:75px; } @media  all  and  (max-­‐width:  600px)  {        #test3  {                display:none;        } }
102. Image override with a media query http://timkadlec.com/2012/04/media-query-asset-downloading-results/ <div  id="test4"></div> #test4  {        background-­‐image:url('images/test4-­‐desktop.png');        width:200px;        height:75px; } @media  all  and  (max-­‐width:  600px)  {        #test4  {                background-­‐image:url('images/test4-­‐mobile.png');        } }
103. #3 Conditionally load JS based on screen size and capabilities http://www.flickr.com/photos/lyza/7382255242/
104. <iframe id="map" width="300" height="300" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://maps.google.com..."></iframe> Extremely long URL abbreviated This single iframe causes 47 files to be downloaded!
105. 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> Extremely long URL abbreviated This single iframe causes 47 files to be downloaded!
106. https://github.com/paulirish/matchMedia.js In JavaScript, use matchMedia() or a poly ll for it to test a media query
107. <a  href="articles/latest/"            data-­‐append="articles/latest/fragment"            data-­‐media="(min-­‐width:  30em)">          Latest  Articles </a> https://github.com/filamentgroup/Ajax-Include-Pattern/ Use AJAX to bring more content into the page as the viewport width gets bigger AJAX Include Pattern
108. Behaviorial Breakpoints Better yet, keep your breakpoints in your CSS and have your JavaScript watch to changes to the DOM triggered by media queries.
109. Deliver different size <IMG>s at different screen sizes #4 http://www.flickr.com/photos/kk/230544325/
110. <img src="brews_images/bensons_bubbler.jpg" alt="Bensons Bubbler"> There are 16 beer labels on the On Tap Now page that use an img tag like this one for the Bensons Bubbler. Despite the need for multiple versions of this image depending on the screen size, HTML only allows one value for the src.

123. Standards process is still moving forward http://www.flickr.com/photos/johnlamb/2576062549/
124. Get Involved at Responsiveimages.org
125. In the meantime, pick a hack. My fave is PictureFill. <div  data-­‐picture  data-­‐alt="A  giant  stone  face  at  The  Bayon  temple  in  Angkor  Thom,  Cambodia">        <div  data-­‐src="small.jpg"></div>        <div  data-­‐src="medium.jpg"  data-­‐media="(min-­‐width:  400px)"></div>        <div  data-­‐src="large.jpg"  data-­‐media="(min-­‐width:  800px)"></div>                <!-­‐-­‐  Fallback  content  for  non-­‐JS  browsers.    -­‐-­‐>        <noscript>                <img  src="small.jpg"  alt="A  giant  stone  face  at  The  Bayon                  temple  in  Angkor  Thom,  Cambodia">        </noscript> </div> https://github.com/scottjehl/picturefill
126. Handle high-density (retina) images very carefully #5 http://www.flickr.com/photos/kk/230544325/

129. Apple.com is an anti-pattern. Downloads both standard and retina. The total size of the page goes from 502.90K to 2.13MB when the retina versions of images are downloaded.
130. If possible, use CSS for now. @media  screen  and  (-­‐webkit-­‐device-­‐pixel-­‐ratio:  1)  {  /*  Image  for  normal  displays.  */ #main  { background-­‐image:  url(dog.jpg); } } @media  screen  and  (-­‐webkit-­‐min-­‐device-­‐pixel-­‐ratio:  2)  {  /*  Image  for  high  resolution  displays.  */ #main  { background-­‐image:  (dog-­‐hi-­‐res.jpg); } }
131. Foresight.js
132. PictureFill User Preference Branch Tap HD/SD to switch image density https://github.com/scottjehl/picturefill/tree/user-prefs
133. Compressive Images? http://blog.netvlies.nl/design-interactie/retina-revolution/
134. If I could dream up my ideal solution…
135. 8 guidelines and 1 immutable rule
136. Use vector-based images or font icons whenever you can #1
137. IcoMoon.io makes font icons easy IcoMoon App Premium Icons Font CDN Browse 3800+ Free Vector Icons 1200+ Vector Icons & Counting Serve Custom-Built Fonts IcoMoon IcoMoon Custom Built and Crisp Icon Fonts, Done Right Home App Icon Packs Font CDN Demo Documentation Blog About
138. Grumpicon.com helps with SVG Based on open source grunticon /' // . // |\//7 /' " \ . | ( \ _ _ - -_ | '._ ' _ __ _- \_ _/ \'-' // \\_/ \\ | | || | / / | \ / |VV ||--\__________/-||-/| || || || || { } { } { }{ } . . Drag & Drop ur SVGs on the Grumpicon plz. What Is This Issues?
139. Encourage people to upload the highest quality source possible #2
140. Provide an automatic image resizing and compression service #3
141. Images can be resized to any size with URL parameters #4 <img src="http://src.sencha.io/320/http://sencha.com/files/u.jpg" alt="My constrained image" />
142. “Save for the Web” should be a thing of the past. —@adambradley “
143. Provide automated output of PictureFill or alternative #5 { "source":"/source.jpg", "breakpoints":  [ {  "max-­‐width":"30em","pixel-­‐density":1,"width":360px},   {  "max-­‐width":"30em","pixel-­‐density":2,"width":720px}, {  "max-­‐width":"30em","pixel-­‐density":1,"width":800px}, {  "max-­‐width":"30em","pixel-­‐density":2,"width":1600px}, {  "pixel-­‐density":1,"width":800px}, {  "pixel-­‐density":2,"width":1600px}, ] } templates contain breakpoint information Responsive Images Markup Function PictureFill  Markup Sample syntax. Don’t get hung up on details. Markup for all images can be changed in one spot.
144. Provide a way to override resized images for art direction needs #6
145. Integrate image compression best practices #7 jpegtran or jpegoptim OptiPNG or PNGOUT far future expires headers
146. Bonus: Detect support for WebP image format and use it #8 The average WebP le size is 25% - 34% smaller compared to JPEG le size. WebP compresses 34% better than libpng, and 26% better than pngout for loseless images.
147. The only rule for your responsive images implementation: Plan for the fact that it will be deprecated. Make it easy to change.
148. It’s three years later. Let’s revisit my original question.
149. http://www.flickr.com/photos/theyoungthousands/4025421438 Can a one-size ts all solution…
150. compete with a tailored experience? http://www.flickr.com/photos/fronx/2862975043
151. Or will it always be TOO BIG? http://www.flickr.com/photos/haddadi/5971508861
152. Unlikely responsive design will ever be as fast as something crafted speci cally for a device. http://www.flickr.com/photos/quarenta/3256329577
153. But web design is a balancing act… http://www.flickr.com/photos/kalexanderson/6266452817
154. And performance is just one factor.
155. For most projects, responsive design will be fast enough… Flickr: Uploaded February 11, 2007 by hawridger
