What is HTML5? And why is it so important?

Standard IMPROVEMENTS You dont get rid of HTML4 standards you just improve upon them!

Its easy for web developers to upgrade their websites to HTML 5 Step 1: change the doctype at the top of the page. NEW: OLD:

Who will see your cool new HTML 5 features? Changing the Doctype will not break your existing website People using OLDER browsers that dont support the new HTML5 features will simply miss out on viewing the website the way others do.

HTML5 is a Collection of Features HTML5 is not an all or nothing capability. The HTML5 features available to end users depend on what browser and what version of that browser they are using. Users: How well does your browser support html5? Keep your browser updated so that as they add new feature support you will have access to these new features!

Quick Note about MicroData MicroData is code a web developer adds to a web page that provides a mechanism for easily allowing machines to consume the data on the page, while not affecting the experience for the user. Browsers are applications used by humans to view web pages. Robots are machines (used by search engines) to read the code of the web page. Web Developers add microdata to a web page to help search engine robots better understand the content on the page. If your browser doesnt support microdata dont worry about it! Its not aboutYOU Its about the robot!

HTML5 Enhancing websites for the people.

Detect using a detection library Modernizr is an open source, JavaScript library that detects support for many HTML5 & CSS3 features. Simply include a link to the script in the tag of your master template file Modernizr will run automatically and create a global object called Modernizr. This object contains a set of Boolean properties for each feature it can detect. (Booleans are variables that hold a true or false value).

HTML5 Local Storage Local storage provides a way for websites to store information on your computer to retrieve it later. (similar to cookies) Cookies require a trip to the server on each page download (which requires extra bandwidth). Local storage is accessed by JavaScript (that runs in the client = less bandwidth). If (Modernizr.localstorage){ // find out where the user is located } Else { // user misses out on features }

HTML5 PlaceholderText Enables websites the ability to place temporary text in an input field. This gives the user a visual clue as to what type of text is expected. The placeholder text disappears once the user clicks on the field to begin typing. If (Modernizr.input.placeholder){ // user can see placeholder text} Else { // user cant see the text. }

HTML5 Form InputType New form input types assist users with input. - for sliders - for color pickers - for telephone numbers - for web addresses - for email addresses for calendar date pickers - for a list of months - for weeks - timestamps -for precise, absolute date+time stamps for local dates and times - for spinboxes - for search boxes If (!Modernizr.inputtypes.date){ // not supported} }

HTML5 Autofocus Allows the cursor to automatically be placed in a specific field on a form without the user having to manually click inside the field. If (Modernizr.input.autofocus){ // help the user get started} Else { // user is on their own. } EXAMPLE:

HTML 5Video Each HTML5 browser support 2 different video formats. Make the video available in several different formats. (.mp4 .ogg .webm) The video played depends on the format that browser supports. If (Modernizr.video){ if (Modernizr.video.webm) { // playWebM } else if (Modernizr.video.ogg) { // play Ogg } else if (Modernizr.video.h264) { // play mp4 - h.264 video with AAC audio } Else { // user misses out on features check out the alternative options at video for everyone} } Also see: Video for Everyone www.camendesign.com/code/video_for_everybody

HTML5 Canvas Canvas is a rectangle in your page where you can use JavaScript to draw anything you want. The canvas API is used for drawing shapes, defining paths, creating gradients, and applying transformations. The canvas text API is for drawing text. If (Modernizr.canvas){ // draw something in the box } Else { // user is blind! } Those using a browser without HTML5 support just miss out on viewing the canvas! If (Modernizr.canvastext){ // draw some text in the box } Else { // user is blind! }

HTML5 Canvas A canvas area is created with HTML5 code. Canvas supported in IE9+ You can then access the canvas by referencing its ID. function drawBoxInsideCanvas( ) { var canvasArea = document.getElementById(myCanvas1 ); var canvasContext = canvasArea.getContext(2d); canvasContext.fillRect(50,25,150,100); }

HTML5 Canvas Draw lines. Canvas supported in IE9+ Draw shapes. Fill shapes with gradients. Draw images. WHY? Because its faster download time.

HTML5 WebWorkers WebWorkers provide a way for browsers to run JavaScript in the background (speeding up processing). If (Modernizr.webworkers){ // you can do 2 or more things at once! } Else { // you can only do 1 thing at a time }

HTML5 Offline Offline web applications start out as online web applications. User starts by viewing the online web application. The files are downloaded to the users computer for viewing. User later views these files with no internet connection. When the user gets back online, any changes made will be uploaded to the web server. If (Modernizr.applicationcache){ // window.applicationCache is available } Else { // user cant view website offline. }

HTML5 GeoLocation GeoLocation is the art of figuring out where you are in the world and (optionally) sharing that information with people you trust. Your location can be determines by: your IP address your wireless network connection which cell tower your phone is talking to a dedicated GPS hardware that calculates latitude and longitude from information sent by satellites in the sky.

HTML5 GeoLocation Provide different content on your web pages based on the location of the user. User has to agree to provide their location in order for this to work. Applications can be programmed to return data based on location where longitude and latitude are defined. If (Modernizr.geolocation){ navigator.geolocation.getCurrentPosition(show_map); } Else { // provide static generic information }

Detect support for History API History API is a way to manipulate the browser history via script. If (Modernizr.history){ // history mgmt. works} Else { // try using history.js } Applications can be written to replicate going to a new page yet the web page never refreshes nor does it actually go to a new page.

HTML5 Enhancing websites for the robots.
