Goal: Leave with at least 1
HTML5/CSS3 technique you can use today
“While it continues to serve as a
rough guide to many of the core
features of HTML, it does not
provide enough information to
build implementations that
interoperate with each other and,
more importantly, with a critical
mass of deployed content.”

HTML5 and CSS3 Techniques You Can Use Today
1. Defines a single language called HTML5
which can be written in HTML syntax and in
XML syntax.
2. Defines detailed processing models to foster
interoperable implementations.
3. Improves markup for documents.
4. Introduces markup and APIs for emerging
idioms, such as Web applications.

Add Intellisense & Schema Validation to
Visual Studio editor
• Three options:
–Shiv it
–Kill it
–Target it
• Tags with meaning
<body>
<div id=“header”>
</div>
<div id=“content”>
<div id=“nav”></div>
</div>
<div id=“footer”>
</div>
</body>
<body>
<header>
</header>
<section>
<nav></nav>
</section>
<footer></footer>
</body>
VS.
*Need shiv to trigger styling in old IE
• Content with meaning
– Machines understand more of your content
<!--Facebook Share Microformat for video-->
<meta name="title" content="Baroo? - cute puppies" />
<meta name="description" content="The cutest canine on the Internet!" />
<link rel="image_src" href="http://example.com/thumbnail_preview.jpg" />
<link rel="video_src" href="http://example.com/video_object.swf?id=12345"/>
<meta name="video_height" content="296" />
<meta name="video_width" content="512" />
<meta name="video_type" content="application/x-shockwave-flash" />
• Improved usability
– Supported in Safari, Chrome, Opera (so far)
<form name="f">
<input id="q" autofocus>
<!--Technique to support older browsers-->
<script>
if (!("autofocus" in document.createElement("input"))) {
document.getElementById("q").focus();
}
</script>
<input type="submit" value="Go">
</form>
• data-*
– Valid approach to storing data in HTML
<!--Store values in data-* attributes-->
<div id="mydiv" data-key="26" data-name="My product name">
This product is an extremely popular choice.
</div>
<!--Access values with JavaScript-->
var mydiv=document.getElementById('mydiv')
//Using DOM's getAttribute() property
var key = mydiv.getAttribute("data-key") //returns "26"
//OR Using JavaScript's dataset property**
var key = mydiv.dataset.key //returns "26"

HTML5 and CSS3 Techniques You Can Use Today
• CSS Reset
– Browsers ship with built-in styles – zero them out!
– Enable newer features in older browsers
http://html5reset.org
http://html5boilerplate.com
•-webkit
•-moz
•-o
•-ms “standard” way
browsers implement
custom features.
• Biggest Problem?
– Licensing!
@font-face {
font-family: Delicious;
src: url('Delicious-Roman.otf') format(“opentype”);
}
//Usage
h3 { font-family: Delicious, sans-serif; }
• Solve the licensing problem
• Host the TTF/OTF font files
• Provide easy-to-use code
http://code.google.com/webfonts
http://webfonts.fonts.com
http://typekit.com/libraries
• Easy corner control
– Expect GD for older browsers (IE)
-moz-border-radius: 5px 5px 5px 5px; //Optionally ”explicit”
-webkit-border-radius: 5px;
border-radius: 5px;
//Can also control specific corners
border-bottom-left-radius:0px;
border-bottom-right-radius:0px;
• Exactly like it sounds
– box-shadow: <hShift> <vShift> <size> <color>;
-moz-box-shadow: 2px 2px 2px #333;
-webkit-box-shadow: 2px 2px 2px #333;
box-shadow: 2px 2px 2px #333;
• Uniform across supported browsers!
– text-shadow: <h offest> <v offset> <blur size> <color>;
text-shadow: 2px 2px 2px #333;
//You can apply multiple shadows
text-shadow: 2px 2px 2px #333, 2px 2px 3px #CCC;
• More options, more power
– multiple backgrounds
– resize backgrounds
– background clipping
/*Background size*/
-webkit-background-size: 137px 50px;
-o-background-size: 137px 50px;
background-size: 137px 50px;
/*Multiple Backgrounds*/
background: url(top.gif) top left no-
repeat,
url(bottom.gif) bottom left no-repeat,
url(middle.gif) left repeat-y;
/*Background origin*/
background-origin: border;
/*Other options: padding or content*/
• Not CSS3!
– But useful and desirable
– Can be “shived” to support all browsers
• Use LESS to write less CSS
– Variables, operations, mix-ins, nested rules
/*Variables*/
@primaryColor: #383939;
background-color: @primaryColor;
/*Mix-ins!!*/
.roundedCorners (@radius: 12px) {
-moz-border-radius: @radius;
-webkit-border-radius: @radius;
border-radius: @radius;
}
#page { background-color: @primaryColor; .roundedCorners; }
<link rel="stylesheet/less" href="style.less" type="text/css" />
<script src="http://lesscss.googlecode.com/files/less-1.0.21.min.js"></script>
• Animate by setting CSS properties
– Works when JS is disabled
#id_of_element {
-webkit-transition: all 1s ease-in-out;
-moz-transition: all 1s ease-in-out;
-o-transition: all 1s ease-in-out;
transition: all 1s ease-in-out;
}
• Target styles to specific devices…
– And features!
/*These two rules do the same thing*/
@media all and (min-width:500px) { … }
@media (min-width:500px) { … }
/*Multiple conditions*/
@media screen and (min-width: 600px) and (max-width: 900px) {
.class {
background: #333;
}
}
• Features waiting for friends
WebKit
• Reflections (-
webkit-box-
reflect)
• 3D Transforms (-
webkit-
perspective)
Mozilla
• <Nothing
notable?>
IE (9)
• Hardware
rendering!
• Shiv’r + Inspector
– Simple way to check feature support
– Conditional JS and CSS
.multiplebgs div p {
/* properties for browsers that
support multiple backgrounds */
}
.no-multiplebgs div p {
/* optional fallback properties
for browsers that don't */
}
if (Modernizr.canvas) {
//Canvas supported
}
if (Modernizer.cssColumns){
//Columns supported
}
//Etc...
*Don’t use with IE HTML5shiv. One or the other.
which HTML5/CSS3 technique will you try?
Thanks! Gracias! Mersi! Blagodarya!

HTML5 and CSS3 Techniques You Can Use Today

  • 2. Todd Anglin Chief Evangelist, Telerik Microsoft MVP ASP Insider President NHDNUG & O’Reilly Author @toddanglin TelerikWatch.com
  • 3. • Complete development toolbox provider UI • ASP.NET • MVC • WinForms • Silverlight • WPF Tools • Reporting • ORM • JustCode • CMS Testing • WebUI Test Studio • JustMock Project • TeamPulse • TFS WIM • TFS PD www.telerik.com
  • 4. HTML5 Techniques CSS3 Techniques Practical Tips Goal: Leave with at least 1 HTML5/CSS3 technique you can use today
  • 5. “While it continues to serve as a rough guide to many of the core features of HTML, it does not provide enough information to build implementations that interoperate with each other and, more importantly, with a critical mass of deployed content.” -W3C on HTML4
  • 6. 1991 • HTML Tags 1995 • HTML 2 • Later: File uploads, tables 1997 (Jan) • HTML 3.2 (W3C) 1997 (Dec) • HTML 4 • Strict, Trans, Frameset • 1999: 4.01 HTML5: • Addressing modern web applications & pains of the past
  • 7. 1996 • CSS v1 • IE3: First implementation • IE Mac: First 100% support 1997 • CSS v2 • Still ZERO 100% implementations 2007 • CSS v2.1 • Fixed errors in 2.0 spec CSS: Plagued by implementation bugs & inconsistencies CSS3 • Improve consistency & power of styling language
  • 8. • Better, but not perfect Feature Check • CanIUse.com • BrowserScope.org • Html5Test.com Equalizers • Html5Reset.org • Html5Boilerplate.com • jQuery Hacks • JavaScript helpers • “Downlevel” experiences Know your users. Know your browsers.
  • 13. 1. Defines a single language called HTML5 which can be written in HTML syntax and in XML syntax. 2. Defines detailed processing models to foster interoperable implementations. 3. Improves markup for documents. 4. Introduces markup and APIs for emerging idioms, such as Web applications.
  • 15. • Three options: –Shiv it –Kill it –Target it
  • 16. • Tags with meaning <body> <div id=“header”> </div> <div id=“content”> <div id=“nav”></div> </div> <div id=“footer”> </div> </body> <body> <header> </header> <section> <nav></nav> </section> <footer></footer> </body> VS. *Need shiv to trigger styling in old IE
  • 17. • Content with meaning – Machines understand more of your content <!--Facebook Share Microformat for video--> <meta name="title" content="Baroo? - cute puppies" /> <meta name="description" content="The cutest canine on the Internet!" /> <link rel="image_src" href="http://example.com/thumbnail_preview.jpg" /> <link rel="video_src" href="http://example.com/video_object.swf?id=12345"/> <meta name="video_height" content="296" /> <meta name="video_width" content="512" /> <meta name="video_type" content="application/x-shockwave-flash" />
  • 18. • Improved usability – Supported in Safari, Chrome, Opera (so far) <form name="f"> <input id="q" autofocus> <!--Technique to support older browsers--> <script> if (!("autofocus" in document.createElement("input"))) { document.getElementById("q").focus(); } </script> <input type="submit" value="Go"> </form>
  • 19. • data-* – Valid approach to storing data in HTML <!--Store values in data-* attributes--> <div id="mydiv" data-key="26" data-name="My product name"> This product is an extremely popular choice. </div> <!--Access values with JavaScript--> var mydiv=document.getElementById('mydiv') //Using DOM's getAttribute() property var key = mydiv.getAttribute("data-key") //returns "26" //OR Using JavaScript's dataset property** var key = mydiv.dataset.key //returns "26"
  • 22. • CSS Reset – Browsers ship with built-in styles – zero them out! – Enable newer features in older browsers http://html5reset.org http://html5boilerplate.com
  • 24. • Biggest Problem? – Licensing! @font-face { font-family: Delicious; src: url('Delicious-Roman.otf') format(“opentype”); } //Usage h3 { font-family: Delicious, sans-serif; }
  • 25. • Solve the licensing problem • Host the TTF/OTF font files • Provide easy-to-use code http://code.google.com/webfonts http://webfonts.fonts.com http://typekit.com/libraries
  • 26. • Easy corner control – Expect GD for older browsers (IE) -moz-border-radius: 5px 5px 5px 5px; //Optionally ”explicit” -webkit-border-radius: 5px; border-radius: 5px; //Can also control specific corners border-bottom-left-radius:0px; border-bottom-right-radius:0px;
  • 27. • Exactly like it sounds – box-shadow: <hShift> <vShift> <size> <color>; -moz-box-shadow: 2px 2px 2px #333; -webkit-box-shadow: 2px 2px 2px #333; box-shadow: 2px 2px 2px #333;
  • 28. • Uniform across supported browsers! – text-shadow: <h offest> <v offset> <blur size> <color>; text-shadow: 2px 2px 2px #333; //You can apply multiple shadows text-shadow: 2px 2px 2px #333, 2px 2px 3px #CCC;
  • 29. • More options, more power – multiple backgrounds – resize backgrounds – background clipping /*Background size*/ -webkit-background-size: 137px 50px; -o-background-size: 137px 50px; background-size: 137px 50px; /*Multiple Backgrounds*/ background: url(top.gif) top left no- repeat, url(bottom.gif) bottom left no-repeat, url(middle.gif) left repeat-y; /*Background origin*/ background-origin: border; /*Other options: padding or content*/
  • 30. • Not CSS3! – But useful and desirable – Can be “shived” to support all browsers
  • 31. • Use LESS to write less CSS – Variables, operations, mix-ins, nested rules /*Variables*/ @primaryColor: #383939; background-color: @primaryColor; /*Mix-ins!!*/ .roundedCorners (@radius: 12px) { -moz-border-radius: @radius; -webkit-border-radius: @radius; border-radius: @radius; } #page { background-color: @primaryColor; .roundedCorners; } <link rel="stylesheet/less" href="style.less" type="text/css" /> <script src="http://lesscss.googlecode.com/files/less-1.0.21.min.js"></script>
  • 32. • Animate by setting CSS properties – Works when JS is disabled #id_of_element { -webkit-transition: all 1s ease-in-out; -moz-transition: all 1s ease-in-out; -o-transition: all 1s ease-in-out; transition: all 1s ease-in-out; }
  • 33. • Target styles to specific devices… – And features! /*These two rules do the same thing*/ @media all and (min-width:500px) { … } @media (min-width:500px) { … } /*Multiple conditions*/ @media screen and (min-width: 600px) and (max-width: 900px) { .class { background: #333; } }
  • 34. • Features waiting for friends WebKit • Reflections (- webkit-box- reflect) • 3D Transforms (- webkit- perspective) Mozilla • <Nothing notable?> IE (9) • Hardware rendering!
  • 35. • Shiv’r + Inspector – Simple way to check feature support – Conditional JS and CSS .multiplebgs div p { /* properties for browsers that support multiple backgrounds */ } .no-multiplebgs div p { /* optional fallback properties for browsers that don't */ } if (Modernizr.canvas) { //Canvas supported } if (Modernizer.cssColumns){ //Columns supported } //Etc... *Don’t use with IE HTML5shiv. One or the other.

Editor's Notes

  • #3: HTML5 and CSS3 Techniques You Can Use Today As more browsers deliver rich support for the next generation of standards-based web development, new techniques are enabling web developers to design with unprecedented levels of control. In this session, you’ll learn practical HTML5 and CSS3 techniques that you can use in any web project today. Learn how to easily add drop shadows to HTML objects, how to quickly create rounded corners, how to use custom fonts, and even how to animate with CSS. All techniques will be demonstrated with special attention to cross-browser support and tips for supporting older browsers.
  • #7: http://dev.w3.org/html5/html4-differences/ Goes on to say: The same goes for XHTML1, which defines an XML serialization for HTML4, and DOM Level 2 HTML, which defines JavaScript APIs for both HTML and XHTML. HTML5 will replace these documents.

All elements exist in DOM. Thus, you can attach event handlers. CON: Many objects can hurt perf. CANVAS is PIXEL-based. All elements rendered quickly, but not part of DOM. CON: Harder to interact.
