Dive into HTML5
- 4. What is HTML5? Latest standard for HTML Designed to replace both HTML 4, XHTML, and the HTML DOM Level 2 Previous version of HTML, HTML 4.01, came in 1999 Delivers rich content without the need for additional plugins animation to graphics music to movies games Cross-platform and designed to work with: PC Tablet Smartphone Smart TV
- 5. How Did HTML5 Get Started? Collaborative effort of W3G (World Wide Web Consortium) WHATWG (Web Hypertext Application Technology Working Group) Formulated rules for designing HTML5: New features should be based on HTML, CSS, DOM, and JavaScript The need for external plugins (like Flash) should be reduced Error handling should be easier than in previous versions Scripting has to be replaced by more markup Device-independent Development process should be visible to the public
- 6. <!DOCTYPE> Only one <!doctype> declaration, and it is very simple <!DOCTYPE html> New Features 2D drawing Media playback Support for local storage Content-specific elements Form controls
- 7. <canvas> Used to draw graphics, on the fly, via scripting (usually JavaScript) It is a container for graphics, you must use a script to actually draw the graphics Dude, don’t waste time. Demo it!
- 8. Media Elements <audio> Defines sound or music content <video> Defines video or movie content <source> Defines sources for <video> and <audio> <track> Defines tracks for <video> and <audio> <embed> Defines containers for external applications (like plug-ins) DEMO Time
- 9. Local Storage Web pages can store data locally within the user's browser Web Storage is more secure and faster Data is not included with every server request, but used ONLY when asked for Unlike cookies, the storage limit is far larger (around 5MB) Two new objects for storing data on the client: window.localStorage - stores data with no expiration dateTablet code.sessionStorage - stores data for one session (data is lost when the tab is closed) DEMO Time
- 10. Application Cache Web site can be cached, and accessible without an internet connection Offline browsing - users can use the application when they're offline Speed - cached resources load faster Reduced server load - the browser will only download updated/changed resources from the server
- 11. Semantic Elements Semantic elements = Elements with meaning Clearly describes the element to both the browser and the developer Non-semantic elements: <div> and <span> - Tells nothing about its content Semantic elements: <form>, <table>, and <img> - Clearly defines its content Existing sites today contains HTML code like : <div id="nav">, <div class="header">, or <div id="footer"> to indicate navigation links, header, and footer. So some new elements were created in HTML5
- 13. Semantic Elements in HTML5 DEMO Time!
- 14. New Input Types HTML5 has several new input types for better input control and validation. Color Date Datetime Datetime-local Email Month Number Range Search Tel Time URL Week Not all browsers support all the new input types. However, you can already start using them; If they are not supported, they will behave as regular text fields. DEMO Time!

- Cookies are included with every HTTP request, thereby slowing down your web application by needlessly transmitting the same data over and overCookies are included with every HTTP request, thereby sending data unencrypted over the internet (unless your entire web application is served over SSL)Cookies are limited to about 4 KB of data — enough to slow down your application (see above), but not enough to be terribly usefulWhat we really want isa lot of storage spaceon the clientthat persists beyond a page refreshand isn’t transmitted to the serverhttp://www.w3schools.com/html/html5_webstorage.asphttp://html5demos.com/storage
