Framework agnostic HTML rendering utility with an API inspired by jQuery and React.
$h = new Sirius\Html\Builder;
$h->registerTag('user-login-form', 'MyApp\Html\Components\UserLoginForm');
echo $h->make('user-login-form', ['_form_values' => $_POST]);
which will output something like
<form method="post" action="user/login" class="form form-inline">
<div class="form-control">
<label for="email">Email/Username:</label>
<input type="email" name="email" id="email" value="me@domain.com">
</div>
<!-- the rest of the form goes here -->
</form>
