Html 5 high level

is html4

not some magic bullet, it basically allows more javascript easier

HTML5 Features & Examples

<!DOCTYPE html>

New tags

<header> <nav> article, section, aside, footer, basically replaces divs with ids

Custom Data Attribute

"data-", after the hyphen is up to you, it can be anything

<div data-value="100"></div>

Form Fields

types, email, date, range, search, tel, color

attributes, 'required', min/max, placeholder, pattern (regex) enforcement


Local storage, client side database, key/valueu (JSON), Stores in users browser, 5MB per domain, Data persists, after the browser is shutdown or session is closed, window.localStorage.setItem('key', someValue);

Session storage, just like local storage but data expires once browser window is closed, still client side

Indexed DB, WebSQL is deprecated, Object Store,'Database Name');

Application Cache (offline apps), offline first, cache manifest (*.appcache => file), text file that lists every asset/resource needed to run offline, mimetype: text/cache-manifest, 5MB, more as a chrome app


webworkers (multi-threading), worker = new Worker("Thread.js");, Thread.js, self.onmessage = function(event)..., self.postMessage("recv'd:" +;, worker.onmessage = function(event)..., worker.postMessage('data');


<video controls width="500">, have fallback list, <source src="video.mp4" type="video/mp4" />, <source src="video.ogg" type="video/ogg" />, <embed flash....>
