What is HTML5?▪ HTML5 will be the new standard for HTML.▪ The previous version of HTML, HTML 4.01,

came in 1999. The web has changed a lot since then.

▪ HTML5 is still a work in progress. However, the major browsers support many of the new HTML5 elements and APIs.

Outline▪ What is HTML5?▪ How Did HTML5 Get Started?▪ HTML5 New Features▪ Building an HTML5 Starter Document▪ HTML5 New Semantic/Structural Elements▪ Elements That Are No More▪ HTML5 New Form Elements

How Did HTML5 Get Started?▪ HTML5 is a cooperation between the World Wide Web

Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG).

▪ WHATWG was working with web forms and applications, and W3C was working with XHTML 2.0. In 2006, they decided to cooperate and create a new version of HTML.

▪ Some rules for HTML5 were established:• New features should be based on HTML, CSS, DOM, and JavaScript• Reduce the need for external plugins (like Flash)• Better error handling• More markup to replace scripting• HTML5 should be device independent• The development process should be visible to the public

HTML5 New Features▪ Some of the most interesting new features in

HTML5:• The <canvas> element for 2D drawing• The <video> and <audio> elements for media

playback• Support for local storage• New content-specific elements, like <article>,

<footer>, <header>, <nav>, <section>• New form controls, like calendar, date, time,

email, url, search

Building an HTML5 Starter Document▪ Doctype: <! DOCTYPE html>▪ Character Encoding: <meta charset="utf-8" />▪ JavaScript and CSS Links:

▪ HTML5 starting page: <!DOCTYPE html><html lang="en"><head><meta charset="utf-8" /><title>page title</title><script src="my-javascript-file.js"></script><link rel="stylesheet" href="my-css-file.css" /></head><body></body>

HTML5 New Semantic/Structural Elements

<mark> Defines marked/highlighted text

<meter> Defines a scalar measurement within a known range (a gauge)

<nav> Defines navigation links<progress> Represents the progress of a task<ruby> Defines a ruby annotation (for East Asian typography)<rt> Defines an explanation/pronunciation of characters (for East Asian

typography)

<rp> Defines what to show in browsers that do not support ruby annotations

<section> Defines a section in a document

<time> Defines a date/time<wbr> Defines a possible line-break

Using the header Element to Create a Site Header

▪ Here is a basic example:<header> <img alt="HTML5 Cookbook logo" src="logo.png" /> <h1><a href="#">HTML5 Cookbook</a></h1></header>

▪ You are not restricted to just one header element per page, and it does not have to be at the top of a page.<article> <header> <h1><a href="#">Chapter 1</a></h1> <p>2013.01.01</p> </header> <p>AAAAAAABBBBBBBCCCCCCC.</p></article><article> <header> <h1><a href="#">Chapter 2</a></h1> <p>2013.01.01</p> </header> <p>AAAAAAABBBBBBBCCCCCCC.</p></article>

A typical header element with a site title, logo

The header element is often the first thing on a web page, and it usually contains things like a logo, the website name, or the main site navigation.

Multiple header elements on one page

Using the hgroup Element to Group Headings

▪ Using another new HTML5 element, the hgroup element, you can add further information to your header element.<header> <hgroup> <h1><a href="#">HTML5 Overview</a></h1> <h2>Delicious HTML5 recipes</h2> </hgroup></header>

A main title and a subheader would be inside an hgroup element.

Creating Navigation with the nav Element

▪ It is used to link to other pages within the site or to other parts of the page.<nav> <ul> <li><a href="#">Home</a></li> <li><a href="#">About</a></li> <li><a href="#">Meet the team</a></li> <li><a href="#">News</a></li> <li><a href="#">Contact</a></li> </ul></nav>

The nav Element Inside a header Element

▪ You can put nav in the header as well, because the header allows for introductory and navigational content.<header> <h1>My super HTML5 site</h1> <nav> <ul> <li><a href="#">Home</a></li> <li><a href="#">About</a></li> <li><a href="#">News</a></li> <li><a href="#">Contact us</a></li> </ul> </nav></header>

Multiple Navigation Groups in a Single nav Element

<nav> <h2>Shared</h2> <ul> <li><a href="#">Angkor Wat</a></li> <li><a href="#">Angkor Thom</a></li> <li><a href="#">Pre Rup</a></li> </ul> <h2>Read</h2> <ul> <li><a href="#">Takeo</a></li> <li><a href="#">Bayon</a></li> <li><a href="#">Neakpean</a></li> </ul> <h2>Watched/Listened</h2> <ul> <li><a href="#">Chau Say Thevoda</a></li> <li><a href="#">Tamanon</a></li> <li><a href="#">Ta Prohm</a></li> </ul></nav>

Using the New article Element▪ The article element and the section element (discussed in the next section)

are arguably the two most important new HTML5 structural elements, but they are also two of the most confusing.<article> <header> <h1>HTML5 saves millions!</h1> <p>32nd October 2010</p> </header> <p><strong>aaaaaaaaaa</strong> ccccccccccccccc</p> <h2>Another heading</h2> <ol> <li>bbbbbbbbbbbbbbbbbbbbbb</li> <li>dddddddddddddddddddddd</li> </ol> <blockquote><p>eeeeeeeeeeeeeeeeeee</p></blockquote> <h3>And another heading</h3> <ul> <li>fffffffffffffffffffffffffffffffff</li> <li>ggggggggggggggggggggg</li> </ul> <p>hhhhhhhhhhhhhhhhhhhhhhhhh</p></article>

Basic article element with content

Grouping Content with the section Element

▪ The section element is an area of content or an area of a page that nearly always requires a heading. <h1>Loads News</h1> <section> <h1>Sports News</h1> <p>We'll put sports news here.</p> </section> <section> <h1>Entertainment News</h1> <p>Entertainment news will go here.</p> </section> <section> <h1>Nerdy News</h1> <p>News for nerds will go in this section of the page.</p> </section>

Basic news page with sections highlightedNo CSS Style Use CSS Style

Which Should You Use: article or section?

▪ Section has semantic meaning; it is the grouping of related content.

▪ A section can have articles within it.▪ If you think the content would make sense on

its own, then it is an article.

<h1>Grouping Content with the section Element</h1><article>

<header><h2><a href="#">This is our most important

article</a></h2><p>10th November 2013</p><p>Pellentesque habitant morbi tristique fames ac turpis

egestas.</p></header>

Creating a Sidebar with the aside Element

▪ The aside element is for a group of content that is “tangentially” related to its surrounding content, such as a list of most popular posts, blog categories, or recent comments.

▪ Using aside to Mark Up a “Related Links” Section:

Sidebar

Using the footer Element▪ The footer element, as its name suggests, is typically at the bottom of the

page.<footer >

<small>© Copyright HTML5 2013</small></footer>

▪ Like the header element, you can use footer more than once on a page. You can put a footer inside an article.<article>

<h1>10 things about HTML5</h1><footer>

<p>aaaaabbbbbbcccccccddd</p></footer><p><strong>Pellentesque habitant morbi tristique</strong>...</p><footer>

<p>aaaaannnkjojhu8jid</p></footer>

</article><footer>

<small>© Copyright HTML5 Cookbook 2011</small></footer>

Page layout with multiple footer elements

Figure and figcaption Elements▪ The figure element allows you to wrap an image

and give it a description.▪ You can associate images with a caption, using figcaption.

▪ figure does not always have to include an image.▪ Image with Caption:

Website analytics for October 2010</figcaption>

</figure>

Multiple Images Within figure<figure>

Comparative website analytics for Winter 2010(October, November, December)

</figcaption></figure>

Figure element used to display three images, which share the one caption

figcaption

Marking Up the Date and Time with the time Element

▪ The time element allows you to code dates and times that are readable by machines but are displayed to users in a readable fashion.

▪ The time element has two optional attributes:• datetime• Pubdate

<article><footer><p>This news article was published on <time pubdate datetime="2011-04-01T16:00">1st April 2011 at 4pm</time>by <a href="#">Lawrence Ho</a></p>

</footer></article>

Making a Native Toggle Widget with the details Element

▪ The details element creates an interactive open/close toggle effect, without the need for JavaScript and/or CSS.

▪ The summary element can be used within details to represent the summary of the content.

▪ details has an optional attribute: open. If this is true, it will show the details element open by default.

Example of the details Element<details open>

<summary>Lawrence Ho</summary><figure>

<img alt="" src="images/tom-and-luce.jpg" /><figcaption>Lawrence and her friends</figcaption>

</figure><p>Pellentesque habitant morbi turpis egestas.</p><p>Pellentesque habsuada fames ac turpis egestas.</p><p>Pellentesque habitant malesc turpis egestas.</p><p>Pellentesque habiet malesrpis egestas.</p>

<img alt="" src="chuck.jpg" /><figcaption>MitraStar</figcaption>

</figure><p>Pellentesqetfames ac turpis egestas.</p>

</details>

Highlighting Text with the mark Element▪ The mark element gives the document author a chance to

highlight, or bring attention to, some text in the document.▪ The mark Element with Additional CSS:<style>

mark {background-color: red ; font-weight:bold;}</style><article>

<header><h1>Something in Latin</h1>

</header> <p>Pellentesque et netus et malesuada fames ac turpis egestas. <mark>Vestibulum tortor quam</mark>, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec d leo. </p></article>

The mark element used to highlight text for a user

s Element and cite element

▪ Previously the s element was specifically for strikethrough text.

▪ In HTML5, it has been redefined and is now used to represent content that is no longer correct or relevant.

▪ cite represents the title of a work, such as a book or a song.

Sample of s and cite element

The ol Element▪ The ol element, used to create an ordered list,

has been redefined, so it now has three acceptable attributes:• start• reversed• Type

▪ Reversed Ordered List:<h1>My favorite colors</h1><ol reversed>

<li>Red</li><li>Green</li><li>Blue</li>

Nested Ordered Lists<ol>

<li>Lorem ipsum dolor adipiscing elit.<ol>

<li>Lorem ips, cetuer adipiscing elit.</li>

<li>Aliquam tincidunt mauris eu risus.</li>

<li>Lorem ipsum adipiscing elit.<ol>

<li>Aliquam eu risus.</li>

<li>Vestibulum a dapibus neque.</li>

</ol></li><li>Vestibulum auctor dapibus

neque.</li></ol>

</li><li>Aliquam tincidunt mauris eu risus.</li><li>Vestibulum auctor dapibus neque.</li>

Type Attribute▪ Using the type attribute, you can change the

type of numbering you get on the lists, without the need for CSS. You can choose from five types:• type="1" = 1, 2, 3,4, 5• type="a" = a, b, c, d, e• type="A" = A, B, C, D, E• type="i" = i, ii, iii, iv, v• type="I" = I, II, III, IV, V

Sample of ol element

Elements That Are No More▪ The following HTML 4.01 elements are removed from

HTML5:• acronym(use abbr; see earlier)• applet(use object)• basefont(use CSS for presentation)• big(use CSS for presentation)• center(use CSS for presentation)• frame(though iframestill exists)• frameset• noframes• font(use CSS for presentation)• strike(depending on the content, use sor del)• tt(use CSS for presentation)• u(use CSS for presentation)

HTML5 New Form Elements

<datalist> Specifies a list of pre-defined options for input controls

<keygen> Defines a key-pair generator field (for forms)<output> Defines the result of a calculation

Different input type▪ There are several new input types in HTML5

that are useful for creating forms or updating old forms:• <input required type="email" id="email"

name="email" />• <input required type="tel" id="tel" name="tel" />• <input required type="url" id="url" name="url" />• <input required type="search" id="search"

name="search" />• <input required type="date" id="birthday"

name="birthday" />

WebM -- 13+ 5+ -- -- 11+ --

Enabling Video for All Browsers▪ Because of browser and codec issues, you

have to provide different formats of video within the one video element.

▪ Using the Source Element to Display Different Video Formats:<video width="640" height="480" controls><source src="video.mp4" type="video/mp4" /><source src="video.webm" type="video/webm" /><source src="video.ogv" type="video/ogg" /></video>

New Video Attributes▪ The src Attribute▪ The poster Attribute▪ The preload Attribute:• preload="auto"• preload="none"• preload="metadata"

▪ The autoplay Attribute▪ The controls Attribute

Making Your Own Custom Controls▪ HTML5 provides a JavaScript media API for the video and audio

elements.1. Wrap a <div id="video-wrapper"> around the video element, and add

2. Declare the video element as an object so it can be referenced, and then remove the default browser controls.

3. When the video is ready to play, the Play button is enabled.4. Add functionsand listenersfor the buttons, other controls, and

displays.

Canvas Overview▪ The canvas element gives you a blank surface,

which you can use to render graphics, images, and text dynamically.

▪ The version of each browser that supports the canvas element:

OS type Version

Android 2.1+

Chrome 10.0+

Firefox 3.6+

iOS Safari 3.2+

Opera 10.6+

Safari 3.2+

Canvas Overview▪ The canvas element has the standard

attributes of an HTML element.▪ Minimally, you will need the id, width, and height.

▪ The canvas element can be styled like any other element through CSS.

▪ You could also add a background color or other styles.

Getting Started▪ Setting Up the canvas Element:<!DOCTYPE html><html><head><style>canvas {

border: 1px solid #000;}</style></head><body><canvas id="myCanvas" width="640" height="480"></canvas></body></html>

To draw on the canvas from JavaScript<canvas id="mycanvas" width="640“ height="480"></canvas><script>var canvas = document.getElementById('mycanvas').getContext('2d');</script>▪ The getContext method can be used to verify your JavaScript and determine

whether the current browser supports the canvas drawing.

X and Y Coordinates▪ (X,Y) coordinate system is used to determine

the particular location or pixel that is being updated.

▪ These coordinates are used with the various tools to reference starting points, end points, and other locations.

Canvas Tools▪ Rectangle: Draws a rectangle at a specific

location with a specific width and height.▪ Line: Creates a line from point A to point B.▪ Path: Creates a path using one or more lines

or curves.▪ Arc: Creates an arc given particular

dimensions and employed to also create circles

▪ Curve: Creates one of two types of curves: Bezier or Quadratic

Laying a Grid on the Canvas▪ The canvas element uses the grid system for the basic

shape-drawing tools, effects, and transformations.▪ Use two of the basic shape methods, line and arc.▪ fillText, that allows the JavaScript to apply text to the canvas element.

▪ Make the grid visible by following these steps:1. Create a blank HTML page with the html body tags

including the canvas opening and closing tags, and fallback text in between.

2. Add the style section with the canvas id style.

A Sample of grid coordinate system▪ The canvas grid coordinate system drawn by using

the line, arc, and fillText methods:

Drawing Polygons with a Path▪ Use the line drawing and path functionality of the Canvas API to draw a

regular polygon based on a number of sides and radius provided by the user.

▪ The polygons can be created by following the steps:1. Create the page with the style and body tags for the canvas.2. Add the input fields for the number of sides and radius along with

the button to trigger the drawing of the polygon. 3. Add the init function, global variables, and load event handler to

set the global references to the canvas and context.4. Add the drawPolygon function, which is the worker function for

drawing the actual regular polygon.

A Sample of Polygons▪ Polygon created with 7 sides and a radius of 150 via

the path functionality:

The Samples of Cavans

Dealing with Internet Explorer▪ IE6, 7, and 8, by default, do not recognize the

new HTML5 elements.▪ you can programmatically create them

through JavaScript as part of the DOM, as in this example:<script>document.createElement('article');document.createElement('section');//and so on</script>

HTML5Shiv▪ The “shiv” is designed to allow versions prior to IE9 to

recognize the HTML5 elements and allow them to be styled using CSS.

▪ Using the HTML5 Shiv:<!DOCTYPE html><html lang="en"><head>

</head>

Making CSS Compatible▪ To make sure IE plays nice, you need to set

your new elements to display: block.▪ Setting Up New Elements in CSS:

article, aside, details, figcaption, figure, footer, header, hgroup, nav, section {display: block;}

Using Modernizr to Detect Features▪ Modernizr is a JavaScript library (found at

http://modernizr.com) that detects what HTML5 and CSS3 features the browser supports.

▪ It does not fill in the gaps and add the missing functionality.

▪ The Modernizr library is simple to use and has been integrated into major and minor sites around the world.

Feature Detection with Modernizr and JavaScript

<!DOCTYPE html><html class="no-js“ lang="en"><head>

alert('SessionStorage is supported.');} else {

alert('SessionStorage is not supported.');}</script>

</head><body></body></html>

New Layout and Style Techniques with CSS3

▪ CSS level 3 (CSS3) is the latest iteration of the CSS specification.

▪ CSS3 Media Queries gives you the ability to target specific screen widths, heights, and even orientation, so you can target smartphones like the iPhone or Android phone, as well as new tablet devices like the iPad, all with CSS.

Simple Media Query Example▪ You could have several different media queries

as you attempt to target all different types of devices, resolutions, and screen orientation.

Media Queries Inside a CSS Filebody {background: black; color: #fff; font: normal 62.5%/1.5 tahoma, verdana, sans-serif;}h1 {font-size: 2em;}p {font-size: 1.4em;}/* styles for smartphones and very small screen resolution */@media only screen and (min-width: 320px) and (max-width: 400px){body {background: blue;}}/* styles for screen resolutions bigger than smartphones but smaller or equal to 1024px */@media only screen and (min-width: 401px) and (max-width: 1024px){body {background: red;}}/* styles for screen resolutions for a very wide resolution */@media only screen and (min-width: 2000px){body {background: green;}}

Using Custom Fonts with @font-face▪ Using @font-face, you can embed your own font with just a few lines of CSS.▪ @font-face in Its Simplest Form:

Cross-Browser @font-face@font-face {

font-family: 'AnagramRegular';src: url('type/Anagram-webfont.eot');src: url('type/Anagram-webfont.eot?#iefix') format('embedded-opentype'),url('type/Anagram-webfont.woff') format('woff'),url('type/Anagram-webfont.ttf') format('truetype'),url('type/Anagram-webfont.svg#webfontCiw7vqzS') format('svg');

Making Multiple Backgrounds with CSS Gradients▪ Gradient Device and Browser Support:

▪ Simple CSS Linear Gradient:body {

background: url(gradient.gif); /* for browsers that can't do gradients */background: -moz-linear-gradient(white, gray);background: -webkit-linear-gradient(white, gray);background: -linear-gradient(white, gray);
