Примеры инициализации

use \Motokraft\Pagination\Pagination;
use \Motokraft\HtmlElement\HtmlElement;

// Добавляем класс из примера выще
Pagination::addRenderer('demo', DemoPagination::class);

$div = new HtmlElement('div');

$pagination = new Pagination(367, 0, 10, 9);
$pagination->render($div, 'demo');

echo $div;
