First create a layout file as views/layouts/main-layout.php:

<?php
/**
 * views/layouts/main-layout.php
 *
 * @var $this \Nullai\Vista\Engines\ViewRenderEngine
 */
?>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>My Site</title>
        <?php $this->yield('scripts'); ?>
    </head>

    <body>
        <?php $this->yield('main');  ?>

        <?php $this->yield('footer'); ?>
    </body>
</html>

​
Apply Layout

Next, create a file that uses the layout views/home.php:

<?php
/**
 * views/home.php
 *
 * @var $this \Nullai\Vista\Engines\ViewRenderEngine
 * @var $content string
 */
$this->layout('layouts.main-layout');

// Yielded by the layout's $this->yield('main')
echo $content;
?>

<?php $this->section('scripts'); ?>
<script>
    console.log(<?= json_encode(['site' => '<My Site>'], JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_AMP | JSON_HEX_QUOT) ?>);
</script>
<?php $this->end(); ?>

<?php $this->section('footer'); ?>
<footer>My footer</footer>
<?php $this->end(); ?>
