#Canteen HTML5

Create dynamic, well-formatted HTML5 markup with a simple an intuitive PHP API. This is a fork/rewrite of the [Gagawa](https://code.google.com/p/gagawa/) project. CanteenHTML5 is a concise, flexible and easy to remember API which makes it possible to create simple markup (such as a link) or more complex structures (such a table, document or nested list). All tags and attribute names are validated against the current HTML5 specification.

For documentation of the codebase, please see [Canteen HTML5 docs](http://canteen.github.io/CanteenHTML5/).

##Requirements


This library requires a webserver running PHP 5.3+. Also, the root namespace for the library is `Canteen\HTML5`.

##Installation

Install is available using [Composer](http://getcomposer.org).

```bash
composer require canteen/html5 dev-master
```

Including using the Composer autoloader.

```php
require 'vendor/autoload.php';
```

##Usage

###Basic
To create an HTML node, simply call global `html` method, passing in the tag name and then any attributes.

```php
// Enable the global use of html()
Canteen\HTML5\HTML5::useGlobal();

// Turn on autoloading if not using composer's autoloading
Canteen\HTML5\HTML5::autoload();

echo html('img src=home.jpg');
echo html('img', 'src=home.jpg'); 
echo html('img', array('src'=>'home.jpg')); 
```

All of these examples would output:

```html
<img src="home.jpg" />
```

###Adding Attributes

There are  dfferent ways to add attributes for HTML container nodes such as `<p>`, `<div>`, or in the example below, `<nav>`.

1. Part of the tag

    ```php
    echo html('nav title="Navigation" class=main', 'Welcome');
    ```
    
2. As an associative array

	```php
    echo html('nav', 'Welcome', array('title'=>'Navigation', 'class'=>'main'));
    ```

3. As a shorthand string

	```php
    echo html('nav', 'Welcome', 'title="Navigation" class=main');
    ```
    
4. As an property methods

  ```php
  $nav = html('nav', 'Welcome');
  $nav->class = 'main';
  $nav->title = 'Navigation';
  echo $nav;
  ```

All of these examples output the same markup:
```html
<nav title="Navigation" class="main">Welcome</nav>
```

###Adding Nested Elements

Any HTML5 container tags (such as `<p>`, `<span>`, or `<div>`) can have child elements. These elements can be strings or other HTML5 element objects.

```php
$label = html('span', 'Website!');
$link = html('a', $label);
$link->href = 'http://example.com';
echo $link; 
```

Alternatively, use the `addChild` method for any container tag.

```php
$link = html('a');
$link->href = 'http://example.com';
$link->addChild(html('span', 'Website!'));
echo $link;
```

Or `appendTo` to target a container to be added to:

```php
$link = html('a');
$link->href = 'http://example.com';
html('span', 'Website!')->appendTo($link);
echo $link;
```
All examples would output:

```html
<a href="http://example.com"><span>Website!</span></a> 
```

###CSS Selectors

Tag names can optionally have CSS-style class and id selectors:

```php
echo html('a#example'); //<a id="example"></a>
echo html('span.small'); //<span class="small"></span>
echo html('span.small.label'); //<span class="small label"></span>
echo html('span#example.small.label'); //<span id="example" class="small label"></span>
```

###Additional Components

####Document
