Make the checkout page very modern and nice (Laravel, PHP)

My project is to create a modern and attractive checkout page for a destination website built using Laravel and PHP. I want the checkout page to be vibrant and eye-catching, so the design will need to be aesthetically pleasing as well as effective. I'd like for the checkout page to be responsive, so that it fits any screen size and viewport of the user. Additionally, the checkout page should have autofill options for easy use of customers. Furthermore, for secure payment processing, the checkout page should have secure payment processing capabilities. To make this robust, I would like to use MySQL, MongoDB or PostgreSQL as the database technology.

Here the page:
