    • MULTI-SCREEN HTML5 Ron Reiter
    • Who am I? •  Ron Reiter •  HTML5 Google Developer Expert •  HTML5-IL •  Consultant, Freelancer
    • HTML5 != WEB •  HTML5 is a platform for writing applications •  Browser + Server = Web !=  
    • Why mobile web? •  Global mobile traffic now represents roughly 13% of Internet traffic •  Gartner research: In 2013 more than half of users will surf the web via smartphones •  Nearly 1/3 of UK page views are from mobiles and tablets BECAUSE YOU NEED TO DO IT
    • Why HTML5? •  Cross platform development •  FirefoxOS •  PhoneGap •  Desktops run JavaScript with great performance •  Devices are only getting stronger (Zuckerberg, kiss my *ss)
    • Why NOT HTML5? •  Millisecond grade interaction and animations •  HTML5 is not quite there yet
    • Why Multi-screen?
    • CSS Media Queries
    • CSS Media Queries - Before $(window).resize(  function()  {          if  ($(window).width()  <  480)  {              document.body.className  =  “smartphone”;          }  else  if  ($(window).width()  >=  480  &&  $(window).width()  <  940)  {              document.body.className  =  “tablet”;          }  else  {              document.body.className  =  “desktop”;          }    });  
    • CSS Media Queries - After @media  (max-­‐width:  479px)  {    }    @media  (min-­‐width:  480px)  and  (max-­‐width:  939px)  {    }    @media  (min-­‐width:  940px)  {    }      
    • CSS Media Queries - After <link  rel="stylesheet"        type="text/css"  media="screen"  href="sans-­‐serif.css">    <link  rel="stylesheet"        type="text/css"  media="print"  href="serif.css">  
    • CSS Media Queries - After @import  url(responsive-­‐retina.css)  (-­‐webkit-­‐min-­‐device-­‐pixel-­‐ratio:  1.5),  (min-­‐resolution:  144dpi);  
    • Important media queries •  print  /  screen  •  orientation  •  min-­‐width  •  max-­‐width  •  min-­‐device-­‐width  •  max-­‐device-­‐width  •  -­‐webkit-­‐min-­‐device-­‐pixel-­‐ratio    /  min-­‐resolution    
    • Why is this better? •  Declarative CSS allows hardware acceleration •  Browser Optimizations •  Less ugly
    • Viewport meta tag •  This viewport tag disables mobile viewport resizing: <meta  name="viewport”  content=”          width=device-­‐width,  initial-­‐scale=1.0,  maximum-­‐scale=1.0,  user-­‐scalable=no   ”>  •  Use it when you build responsive interfaces
    • App or mobile web? •  You already have your website, and now you want to support mobile devices. •  Website –  Easier maintenance •  Application –  More abilities
    • What are my options? •  Change your current website to a responsive web site •  Your original website + Special website for tablets and smartphones •  Just make an app (HTML5, native, etc).

    • jQuery Mobile •  Amazing mobile framework •  Themable •  Cross Platform •  Around for a while
    • jQuery Mobile Prototyping - Codiqa

    • jQuery Mobile Architecture & Navigation
    • jQuery Mobile Architecture AJAX  /  Preloaded Web  NavigaMon  One  HTML,  Two  pages   Two  HTMLs,  Two  pages  
    • AJAX Navigation •  Instead of changing the document location, we use $.mobile.navigate (saves history) $(“a”).on(“click”,  function(  event  )  {    event.preventDefault();    $.mobile.navigate  (  this.attr(“href”)  );  });  
    • AJAX Navigation •  Once we navigate, a “navigate” event is fired  $(window).on(“navigate”,  function(event,  data)  {          //  load  new  content  using  AJAX  });  
    • Navigating between loaded pages JavaScript:  $.mobile.changePage(“#page2”,  “pop”,  false,  true);  $.mobile.back();  HTML:  <div  data-­‐role=“page”  id=“page1”></div>  <div  data-­‐role=“page”  id=“page2”></div>  
    • Creating a page dynamically JavaScript:    $(document.body).append(<div  data-­‐role="page"  id=”page2"><div  data-­‐role="content">  +  content  +  </div></div>);  $.mobile.initializePage();  $.mobile.changePage(“#page2”,  “pop”,  false,  true);  
    • jQuery Mobile + MVC •  Angular – adapter •  Backbone – we need a special router – •  Ember + jQuery Mobile is a bit harder since both frameworks utilize a fair amount of voodoo
    • OK, I want an app! •  PhoneGap / Apache Cordova – Gives native API access from JavaScript •  PhoneGap was bought by Adobe, so that non- Adobe development is done in Cordova
    • PhoneGap Build •  Removes the need for compiling to all platforms
    • Desktop?
    • Responsive Web Design
    • Responsive Web Design •  Web sites with a simple UI need to adapt to multiple screen form factors •  Web sites are less complicated than web applications, but still very similar •  jQuery mobile is also a tool for responsive web design – rwd.php
    • Twitter Bootstrap
    • Twitter Bootstrap •  UI framework is more straightforward than jQuery Mobile •  The UI elements are not as good for mobile as jQuery Mobile •  Mobile browsers do not behave well with advanced Bootstrap UI elements like jQuery Mobile does
    • How to make Bootstrap responsive? •  Add this to your Bootstrap app: <meta  name="viewport"  content="width=device-­‐width,  initial-­‐scale=1.0">  <link  href="assets/css/bootstrap-­‐responsive.css"  rel="stylesheet">  •  And you’re ready to go!
    • Twitter Bootstrap Grid <div  class=“container”>      <div  class=“row”>  <!-­‐-­‐  columns  must  sum  up  to  12  -­‐-­‐>          <div  class=“span4”>  …  content  …  </div>          <div  class=“span4”>  …  content  …  </div>                  <div  class=“span4”>  …  content  …  </div>      </div>  </div>
