Head

The <head> HTML element contains machine-readable information (metadata) about the document, like its title, scripts, and style sheets.

Basic Usage

Instantiate the Head class using Head::widget().

$head = Head::widget();

Or, block style instantiation.

<?= Head::begin() ?>
    // ... content to be wrapped by `head` element
<?= Head::end() ?>

Setting Attributes

Use the provided methods to set specific attributes for the a element.

// setting class attribute
$head->class('container');

Or, use the attributes method to set multiple attributes at once.

$head->attributes(['class' => 'container', 'style' => 'background-color: #eee;']);

Adding Content

If you want to include content within the head tag, use the content method.

$head->content('MyContent');

Or, use begin() and end() methods to wrap content.

<?= Head::begin() ?>
    My content
<?= Head::end() ?>

Rendering

Generate the HTML output using the render method, for simple instantiation.

$html = $head->render();

For block style instantiation, use the end() method, which returns the HTML output.

$html = Head::end();

Or, use the magic __toString method.

$html = (string) $head;

Common Use Cases

Below are examples of common use cases:

// adding multiple attributes
$head->class('external')->content('MyContent');

// using data attributes
$head->dataAttributes(['analytics' => 'trackClick']);
