HTML5 introduction

HTML5 is the next generation of HTML.

What is HTML5?

HTML5 will be the new standard for HTML, XHTML, and the HTML DOM.
The previous version of HTML came in 1999. The web has changed a lot since then.
HTML5 is still a work in progress. However, most modern browsers have some HTML5 support.

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

New Features

Some of the most interesting new features in HTML5:
  • The canvas element for drawing
  • The video and audio elements for media playback
  • Better support for local offline storage
  • New content specific elements, like article, footer, header, nav, section
  • New form controls, like calendar, date, time, email, url, search

Browser Support

HTML5 is not yet an official standard, and no browsers have full HTML5 support.
But all major browsers (Safari, Chrome, Firefox, Opera, Internet Explorer) continue to add new HTML5 features to their latest versions.

HTML5 New Elements

HTML5 New Elements


New Elements in HTML5

The internet has changed a lot since HTML 4.01 became a standard in 1999.
Today, some elements in HTML 4.01 are obsolete, never used, or not used the way they were intended to. These elements are deleted or re-written in HTML5.
To better handle today's internet use, HTML5 also includes new elements for better structure, drawing, media content, and better form handling.

New Markup Elements

New elements for better structure:
Tag Description
<article> Specifies independent, self-contained content, could be a news-article, blog post, forum post, or other articles which can be distributed independently from the rest of the site.
<aside> For content aside from the content it is placed in. The aside content should be related to the surrounding content
<bdi> For text that should not be bound to the text-direction of its parent elements
<command> A button, or a radiobutton, or a checkbox
<details> For describing details about a document, or parts of a document
<summary> A caption, or summary, inside the details element
<figure> For grouping a section of stand-alone content, could be a video
<figcaption> The caption of the figure section
<footer> For a footer of a document or section, could include the name of the author, the date of the document, contact information, or copyright information
<header> For an introduction of a document or section, could include navigation
<hgroup> For a section of headings, using <h1> to <h6>, where the largest is the main heading of the section, and the others are sub-headings
<mark> For text that should be highlighted
<meter> For a measurement, used only if the maximum and minimum values are known
<nav> For a section of navigation
<progress> The state of a work in progress
<ruby> For ruby annotation (Chinese notes or characters)
<rt> For explanation of the ruby annotation
<rp> What to show browsers that do not support the ruby element
<section> For a section in a document. Such as chapters, headers, footers, or any other sections of the document
<time> For defining a time or a date, or both
<wbr> Word break. For defining a line-break opportunity.


New Media Elements

HTML5 provides a new standard for media content:
Tag Description
<audio> For multimedia content, sounds, music or other audio streams
<video> For video content, such as a movie clip or other video streams
<source> For media resources for media elements, defined inside video or audio elements
<embed> For embedded content, such as a plug-in
<track> For text tracks used in mediaplayers


The Canvas Element

The canvas element uses JavaScript to make drawings on a web page.
Tag Description
<canvas> For making graphics with a script


New Form Elements

HTML5 offers more form elements, with more functionality:
Tag Description
<datalist> A list of options for input values
<keygen> Generate keys to authenticate users
<output> For different types of output, such as output written by a script

New Input Type Attribute Values

Also, the input element's type attribute has many new values, for better input control before sending it to the server:
Type Description
tel The input value is of type telephone number
search The input field is a search field
url The input value is a URL
email The input value is one or more email addresses
datetime The input value is a date and/or time
date The input value is a date
month The input value is a month
week The input value is a week
time The input value is of type time
datetime-local The input value is a local date/time
number The input value is a number
range The input value is a number in a given range
color The input value is a hexadecimal color, like #FF8800
placeholder Specifies a short hint that describes the expected value of an input field

HTML5 Video

HTML5 Video


Many modern websites show videos. HTML5 provides a standard for showing them.

Check if your browser supports HTML5 video



Videos on the Web

Until now, there has never been a standard for showing a video or movie on a web page.
Today, most videos are shown through a plugin (like flash). However, different browsers may have different plugins.
HTML5 defines a new element which specifies a standard way to include video: the <video> element.

Video Formats

Currently, there are 3 supported video formats for the video element:
Format IE Firefox Opera Chrome Safari
Ogg No 3.5+ 10.5+ 5.0+ No
MPEG 4 9.0+ No No 5.0+ 3.0+
WebM No 4.0+ 10.6+ 6.0+ No
  • Ogg = Ogg files with Theora video codec and Vorbis audio codec
  • MPEG4 = MPEG 4 files with H.264 video codec and AAC audio codec
  • WebM = WebM files with VP8 video codec and Vorbis audio codec

How It Works

To show a video in HTML5, this is all you need:

Example

<video width="320" height="240" controls="controls">
  <source src="movie.mp4" type="video/mp4" />
  <source src="movie.ogg" type="video/ogg" />
  Your browser does not support the video tag.
</video>

Try it yourself »
The control attribute adds video controls, like play, pause, and volume.
It is also a good idea to always include width and height attributes. If height and width are set, the space required for the video is reserved when the page is loaded. However, without these attributes, the browser does not know the size of the video, and cannot reserve the appropriate space to it. The effect will be that the page layout will change during loading (while the video load).
You should also insert text content between the <video> and </video> tags for browsers that do not support the <video> element.
The <video> element allows multiple <source> elements. <source> elements can link to different video files. The browser will use the first recognized format.
Today, Firefox, Opera, and Chrome support Ogg files. Internet Explorer, Chrome, and Safari support MPEG4 files.
To cover all the major browsers, use two <source> elements: One pointing to an MPEG4 file, and one pointing to an Ogg file.


HTML5 video Tags

Tag Description
<video> Defines a video or movie
<source> Defines multiple media resources for media elements, such as <video> and <audio>
<track> Defines text tracks in mediaplayers

HTML5 Audio

HTML5 Audio


HTML5 provides a standard for playing audio.

Audio on the Web

Until now, there has never been a standard for playing audio on a web page.
Today, most audio are played through a plugin (like flash). However, not all browsers have the same plugins.
HTML5 specifies a standard way to include audio, with the audio element.
The audio element can play sound files, or an audio stream.

Audio Formats

Currently, there are 3 main formats for the audio element:
Format IE 9 Firefox 3.5 Opera 10.5 Chrome 3.0 Safari 3.0
Ogg Vorbis No Yes Yes Yes No
MP3 Yes No No Yes Yes
Wav No Yes Yes Yes Yes


How It Works

To play an audio file in HTML5, this is all you need:
<audio src="song.ogg" controls="controls">
</audio>
The control attribute is for adding play, pause, and volume controls.
Insert content between the <audio> and </audio> tags for browsers that do not support the audio element:

Example

<audio src="song.ogg" controls="controls">
Your browser does not support the audio element.
</audio>

Try it yourself »
The example above uses an Ogg file, and will work in Firefox, Opera and Chrome.
To make the audio work in Internet Explorer and Safari, add an audio file of the type MP3.
The audio element allows multiple source elements. Source elements can link to different audio files. The browser will use the first recognized format:

Example

<audio controls="controls">
  <source src="song.ogg" type="audio/ogg" />
  <source src="song.mp3" type="audio/mpeg" />
Your browser does not support the audio element.
</audio>

HTML5 audio Tags

Tag Description
<audio> Defines sound content
<source> Defines multiple media resources for media elements, such as <video> and <audio>

HTML5 Canvas

HTML5 Canvas


The canvas element is used to draw graphics on a web page.
Your browser does not support the canvas element.

What is Canvas?

The HTML5 canvas element uses JavaScript to draw graphics on a web page.
A canvas is a rectangular area, and you control every pixel of it.
The canvas element has several methods for drawing paths, boxes, circles, characters, and adding images.

Create a Canvas Element

Add a canvas element to the HTML5 page.
Specify the id, width, and height of the element:
<canvas id="myCanvas" width="200" height="100"></canvas>


Draw With JavaScript

The canvas element has no drawing abilities of its own. All drawing must be done inside a JavaScript:
<script type="text/javascript">
var c=document.getElementById("myCanvas");
var cxt=c.getContext("2d");
cxt.fillStyle="#FF0000";
cxt.fillRect(0,0,150,75);
</script>

Try it yourself »
 
JavaScript uses the id to find the canvas element:
var c=document.getElementById("myCanvas");
Then, create a context object:
var cxt=c.getContext("2d");
The getContext("2d") object is a built-in HTML5 object, with many methods to draw paths, boxes, circles, characters, images and more.
The next two lines draws a red rectangle:
cxt.fillStyle="#FF0000";
cxt.fillRect(0,0,150,75);
The fillStyle method makes it red, and the fillRect method specifies the shape, position, and size.

Understanding Coordinates

The fillRect method above had the parameters (0,0,150,75).
This means: Draw a 150x75 rectangle on the canvas, starting at the top left corner (0,0).
The canvas' X and Y coordinates are used to position drawings on the canvas.
Mouse over the rectangle below to see the coordinates:
X
Y

More Canvas Examples

Below are more examples of drawing on the canvas element:

Example - Line

Draw a line by specifying where to start, and where to stop:

HTML5 Web Storage

Storing Data on the Client

HTML5 offers two new objects for storing data on the client:
  • localStorage - stores data with no time limit
  • sessionStorage - stores data for one session
Earlier, this was done with cookies. Cookies are not suitable for large amounts of data, because they are passed on by EVERY request to the server, making it very slow and in-effective.
In HTML5, the data is NOT passed on by every server request, but used ONLY when asked for. It is possible to store large amounts of data without affecting the website's performance.
The data is stored in different areas for different websites, and a website can only access data stored by itself.
HTML5 uses JavaScript to store and access the data.

The localStorage Object

The localStorage object stores the data with no time limit. The data will be available the next day, week, or year.
How to create and access a localStorage:

Example

<script type="text/javascript">
localStorage.lastname="Smith";
document.write(localStorage.lastname);
</script>

Try it yourself »
The following example counts the number of times a user has visited a page:

Example

<script type="text/javascript">
if (localStorage.pagecount)
  {
  localStorage.pagecount=Number(localStorage.pagecount) +1;
  }
else
  {
  localStorage.pagecount=1;
  }
document.write("Visits "+ localStorage.pagecount + " time(s).");
</script>


The sessionStorage Object

The sessionStorage object stores the data for one session. The data is deleted when the user closes the browser window.
How to create and access a sessionStorage:

Example

<script type="text/javascript">
sessionStorage.lastname="Smith";
document.write(sessionStorage.lastname);
</script>

Example

<script type="text/javascript">
if (sessionStorage.pagecount)
  {
  sessionStorage.pagecount=Number(sessionStorage.pagecount) +1;
  }
else
  {
  sessionStorage.pagecount=1;
  }
document.write("Visits "+sessionStorage.pagecount+" time(s) this session.");
</script>

HTML5 Input Types

HTML5 New Input Types

HTML5 has several new input types for forms. These new features allow for better input control and validation.
This chapter covers the new input types:
  • email
  • url
  • number
  • range
  • Date pickers (date, month, week, time, datetime, datetime-local)
  • search
  • color

Browser Support

Input type IE Firefox Opera Chrome Safari
email No 4.0 9.0 10.0 No
url No 4.0 9.0 10.0 No
number No No 9.0 7.0 5.1

Date pickers No No 9.0 10.0 5.1
search No 4.0 11.0 10.0 No
color No No 11.0 12 No
Note: Opera has the best support for the new input types. However, you can already start using them in all major browsers. If they are not supported, they will behave as regular text fields.

Input Type - email

The email type is used for input fields that should contain an e-mail address.
The value of the email field is automatically validated when the form is submitted.

Example

E-mail: <input type="email" name="user_email" />

Try it yourself »
Tip: Safari on the iPhone recognizes the email input type, and changes the on-screen keyboard to match it (adds @ and .com options).

Input Type - url

The url type is used for input fields that should contain a URL address.
The value of the url field is automatically validated when the form is submitted.

Example

Homepage: <input type="url" name="user_url" />

Try it yourself »
Tip: Safari on the iPhone recognizes the url input type, and changes the on-screen keyboard to match it (adds .com option).

Input Type - number

The number type is used for input fields that should contain a numeric value.
You can also set restrictions on what numbers are accepted:

Example

Points: <input type="number" name="points" min="1" max="10" />

Try it yourself »
Use the following attributes to specify restrictions for the number type:
Attribute Value Description
max number Specifies the maximum value allowed
min number Specifies the minimum value allowed
step number Specifies legal number intervals (if step="3", legal numbers could be -3,0,3,6, etc)
value number Specifies the default value
Try an example with all the restriction attributes: Try it yourself

Input Type - range

The range type is used for input fields that should contain a value from a range of numbers.
The range type is displayed as a slider bar.
You can also set restrictions on what numbers are accepted:

Example

<input type="range" name="points" min="1" max="10" />

Try it yourself »
Use the following attributes to specify restrictions for the range type:
Attribute Value Description
max number Specifies the maximum value allowed
min number Specifies the minimum value allowed
step number Specifies legal number intervals (if step="3", legal numbers could be -3,0,3,6, etc)
value number Specifies the default value


Input Type - Date Pickers

HTML5 has several new input types for selecting date and time:
  • date - Selects date, month and year
  • month - Selects month and year
  • week - Selects week and year
  • time - Selects time (hour and minute)
  • datetime - Selects time, date, month and year (UTC time)
  • datetime-local - Selects time, date, month and year (local time)
The following example allows you to select a date from a calendar:

Example

Date: <input type="date" name="user_date" />

Try it yourself »
Input type "month": Try it yourself
Input type "week": Try it yourself
Input type "time": Try it yourself
Input type "datetime": Try it yourself
Input type "datetime-local": Try it yourself

Input Type - search

The search type is used for search fields, like a site search, or Google search.
The search field behaves like a regular text field.

Input Type - color

The color type is used for input fields that should contain a color.
The Opera browser will allow you to select a color from a color picker, Google's Chrome will only allow hexadecimal color values to be submitted:

Example

Color: <input type="color" name="user_color" />

HTML5 <input> Tag

Tag Description
<input> Defines an input field

HTML5 Form Elements

HTML5 New Form Elements

HTML5 has several new elements and attributes for forms.
This chapter covers the new form elements:
  • <datalist>
  • <keygen>
  • <output>

Browser Support

Tag IE Firefox Opera Chrome Safari
<datalist> No 4.0 9.5 No No
<keygen> No 4.0 10.5 3.0 No
<output> No 4.0 9.5 10.0 5.1


<datalist> Element

The <datalist> element specifies a list of options for an input field.
The list is created with <option> elements inside the <datalist>.
To bind a <datalist> to an input field, let the list attribute of the input field refer to the id of the datalist:

Example

Webpage: <input type="url" list="url_list" name="link" />
<datalist id="url_list">
<option label="W3Schools" value="http://www.w3schools.com" />
<option label="Google" value="http://www.google.com" />
<option label="Microsoft" value="http://www.microsoft.com" />
</datalist>

Try it yourself »
Tip: The <option> elements should always have a value attribute.

<keygen> Element

The purpose of the <keygen> element is to provide a secure way to authenticate users.
The <keygen> element is a key-pair generator. When a form is submitted, two keys are generated, one private and one public.
The private key is stored on the client, and the public key is sent to the server. The public key could be used to generate a client certificate to authenticate the user in the future.
Currently, the browser support for this element is not good enough to be a useful security standard.

Example

<form action="demo_form.asp" method="get">
Username: <input type="text" name="usr_name" />
Encryption: <keygen name="security" />
<input type="submit" />
</form>

Try it yourself »


<output> Element

The <output> element is used for different types of output, like calculations or script output:

Example

<form oninput="x.value=parseInt(a.value)+parseInt(b.value)">0
<input type="range" name="a" value="50" />100
+<input type="number" name="b" value="50" />
=<output name="x" for="a b"></output>
</form>

Try it yourself »


HTML5 New Form Elements

Tag Description
<datalist> Defines a list of options for an input field
<keygen> Defines a key-pair generator field
<output> Represents the result of a calculation
