Web Constraints
Using this font size, this sentence can fit a screen with a resolution like this. But doesn’t
mean it will fit a screen size like …
Resolutions
Cross-browser Compatibility
One version to rule them all.
Web Constraints
Graceful Degradation
Web Constraints
“Graceful degradation means that your Web site continues to operate even when viewed with less-than-optimal software in which advanced effects don’t work.” Fluid Thinking, by Peter-Paul Koch
Web Constraints
IE9 IE7
Guilty!
But… That doesn’t mean you have to build for the
oldest of the old.

Mobile Focus.
Web vs Native Apps

Common Terminology
Document Object Model (DOM)
Element <head>
Document Root <html>
Element <body>
Element <title>
Element <h1>
Element <p>
Text Node “My name is..”
Text Node “Hello, World”
Text Node “My Site!”
Function Calls function doEquation() { alert(3+ 20); } <script type=“text/javascript”> doEquation(); </script>
Classes and IDs
Hi, I’m a class! I’m seen multiple times in a webpage.
Hi, I’m an ID! I’m unique in a webpage!
.className #idName
Application Programming Interface (API)
API vs SDK
Software Development Kit (SDK)
API vs SDK
HTML History
W3C and WHATWG
HTML5 is Rich
Content has more meaning
Resource Description Framework in Attributes
(RDFa)
<div xmlns:v="http://rdf.data-vocabulary.org/#" typeof="v:Person"> My name is <span property="v:name">Bob Smith</span>, but people call me <span property="v:nickname">Smithy</span>. Here is my homepage: <a href="http://www.example.com" rel="v:url">www.example.com</a>. I live in Albuquerque, NM and work as an <span property="v:title">engineer</span> at <span property="v:affiliation">ACME Corp</span>. </div>
Microformats
<div class="vcard"> <img class="photo" src="www.example.com/bobsmith.jpg" /> <strong class="fn">Bob Smith</strong> <span class="title">Senior editor</span> at <span class="org">ACME Reviews</span> <span class="locality">Desertville</span>, <span class="region">AZ</span> </div>
Microdata <div itemscope itemtype="http://data-vocabulary.org/Person"> My name is <span itemprop="name">Bob Smith</span> but people call me <span itemprop="nickname">Smithy</span>. Here is my home page: <a href="http://www.example.com" itemprop="url">www.example.com</a> I live in Albuquerque, NM and work as an <span itemprop="title">engineer</span> at <span itemprop="affiliation">ACME Corp</span>. </div>
Geolocations var x=document.getElementById("demo"); function getLocation() { if (navigator.geolocation) { navigator.geolocation.getCurrentPosition(showPosition); } else{x.innerHTML="Geolocation is not supported by this browser.";} } function showPosition(position) { x.innerHTML="Latitude: " + position.coords.latitude + "<br />Longitude: " + position.coords.longitude; }
CSS3
Pseudoclasses Pattern Meaning
E:first-child Matches element E when E is the first child of its parent.
E:link E:visited
Matches element E if E is the source anchor of a hyperlink of which the target is not yet visited (:link) or already visited (:visited).
E:active E:hover E:focus
Matches E during certain user actions.
E:nth-of-type(n) an E element, the n-th sibling of its type
Typography
@font-face { font-family: <a-remote-font-name>; src: <source>; font-weight: <weight>; font-style: <style>; }
Detect device type
In your HTML… <meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=no"> In your CSS… @media only screen and (max-width: 480px), only screen and (max-device-width: 480px) { /* CSS overrides for mobile here */ }
Frameworks
For Better Performance & Integration
User Experience Designers must deconstruct designs and interactions
in order to effectively communicate
concepts to Developers.
Redlining

Develop efficiently.
<div> <h1>Formatting</h1> </div>
Develop efficiently.
<!--Commenting-->
Develop efficiently.
Most importantly: Know the standards.
Develop efficiently.
Tables are SO 2004.*
* Tables should be used for tabular data, not site layouts.
Develop efficiently.
