Past | Present | Future

  • 1991: HTML
  • 1994: HTML 2
  • 1996: CSS 1, JavaScript
  • 1997: HTML 4
  • 1998: CSS 2
  • ...[Flash]...
  • 2009: HTML 5 / CSS 3

Note: Aside from adding AJAX in 2005, 
JavaScript hasn't changed

Past | Present | Future

  • Built sites with simple HTML & CSS
  • Used JavaScript sparingly
  • browsername=navigator.appName;
if (browsername.indexOf("Netscape")!=-1) {browsername="NS"}
else if (browsername.indexOf("Microsoft")!=-1) {browsername="MSIE"}

browserversion="0";
if (navigator.appVersion.indexOf("2.")!=-1){browserversion="2"};
if (navigator.appVersion.indexOf("3.")!=-1){browserversion="3"};
  • Relied heavily on server-side code for dynamic functionality
  • Used a lot of Flash.  A lot.

Past | Present | Future

  • Sites are being updated to be more "mobile friendly"
  • Sites are replacing Flash content with JavaScript
  • jQuery to the rescue
    • 9800+ lines of code so you can do this:
    • //Load current temperature from an external webservice
//by passing a zipcode...all without reloading the page$.ajax({url: "/api/getWeather", data: {zipcode: 90210},
  success: function( data ) {
    $( "#temp" ).html(data + " degrees" );
  }
});

qUESTIONS ON css 3?

Let's get real


Dont' forget about jQuery

RWD | RESPONSIVE WEB DESIGN

  1. Fluid foundation (container)
  2. Responsive content
  3. Media Queries

RWD | RESPONSIVE WEB DESIGN


Before we can do anything
 <!-- html -->
<meta 
   name="viewport" content="width=device-width; initial-scale=1.0;">
/* CSS */
@-webkit-viewport { width:device-width; }
@-moz-viewport { width:device-width; }
@-ms-viewport { width:device-width; }
@-o-viewport { width:device-width; }
@viewport { width:device-width; }

RWD | RESPONSIVE WEB DESIGN

A responsive formula:

 target / context = %


/* Fixed */
.container{ width: 600px; }
.sidebar{ width: 200px; }
/* Responsive */
.container{ width: 100%; }
.sidebar{ width: 33.33333%} /* 200 / 600 = 33.33333*/

RWD | Four CSS Approaches


1) Single File

  • Simple to implement
  • Single request
  • Doesn’t require a preprocessor
  • Requires JS to serve large layout to old IE if starting with small layouts
  • Large sites can be difficult to maintain because of the size of the single file

Single File Approach


 /* styles.css */
aside { color: #333; width: 100%; }

/* if the viewport width is 40em or greater */
@media (min-width: 40em) {
aside { width: 50%; }
}
/* if the viewport width is 60em or greater */
@media (min-width: 60em) {
aside { width: 30%; }
}

RWD | FOUR CSS APPROACHES


2) Multiple Files

  • Doesn’t require a preprocessor
  • At least two requests
  • Requires you to separate layout from other styles
  • Allows you to start with small layouts and serve a single large layout to old
  • IE without JS
    • Requests go up if you use multiple MQs

Multiple File approach


<link href=”global.css” rel=”stylesheet”>

<link href=”layout.css” media=”(min-width: 40em)” rel=”stylesheet”>
<!--[if (lt IE 9) & (!IEMobile)]>
  <link href=”layout.css” rel=”stylesheet”>
<![endif]-->

RWD | FOUR CSS APPROACHES


3) Breakpoint-based Partials

  • Allows you to start with small layouts and serve large layout to old IE without JS
  • Only 1 or 2 requests
  • Requires preprocessor
  • Maintenance can be complex

breakpoint-based partials

<link href=”base.css” rel=”stylesheet”>
<!--[if (lt IE 9) & (!IEMobile)]>
  <link href=”no-mq.css” rel=”stylesheet”>
<![endif]-->
base.scss /* Sass */
@import “smallest”;

@media (min-width: 40em) {
  @import “40em”;
}

@media (min-width: 60em) {
  @import “60em”;
}no-mq.scss
  @import “40em”;
  @import “60em”;

RWD | FOUR CSS APPROACHES


4) Module-based Approach

  • Single Request
  • Easy Maintenance
  • Allows you to start with small layouts and serve large layout to old IE without JS
  • Single request for all
  • Requires Preprocessor
