Magento-2 Style attribute value on frontend

Question

I have created attribute using install script

$eavSetup->addAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'mydemo',
            [
                'type' => 'text',
                'backend' => '',
                'frontend' => 'Vendor\ModuleName\Model\Frontend\Style',
                'label' => 'My Demo',
                'input' => 'text',
                'class' => '',
                'source' => '',
                'global' => \Magento\Catalog\Model\ResourceModel\Eav\Attribute::SCOPE_GLOBAL,
                'visible' => true,
                'required' => false,
                'user_defined' => false,
                'default' => 0,
                'searchable' => false,
                'filterable' => false,
                'comparable' => false,
                'visible_on_front' => true,
                'used_in_product_listing' => true,
                'unique' => false,
                'apply_to' => ''
            ]
        );

My frontend model file :

namespace Vendor\ModuleName\Model\Frontend;

class Style extends \Magento\Eav\Model\Entity\Attribute\Frontend\AbstractFrontend
{

    public function __construct(
        \Magento\Eav\Model\Entity\Attribute\Source\BooleanFactory $attrBooleanFactory
    ) {
        parent::__construct($attrBooleanFactory);
    }


    public function getValue(\Magento\Framework\DataObject $object)
    {
        $data = '';
        $value = parent::getValue($object);

        return "<b>{$value}</b>";
    }
}

I want to show attribute value bold on frontend but it's not working. Can anyone suggest me how to achieve this? Any help would be greatly appreciated. Thanks!

I got solution as below:

namespace Vendor\ModuleName\Model\Frontend;

class Style extends \Magento\Eav\Model\Entity\Attribute\Frontend\AbstractFrontend
{

    public function getValue(\Magento\Framework\DataObject $object)
    {
        $this->getAttribute()->setData(\Magento\Catalog\Model\ResourceModel\Eav\Attribute::IS_HTML_ALLOWED_ON_FRONT, 1);
        $data = '';
        $value = parent::getValue($object);

        return "<b>". $value ."</b>";
    }
}
