Intro component with signup form with vanilla JS and A11y

Hi everyone, This is interesting challenge, had some challenges in figuring out how to display custom form validation error messages.

• Used the browser default Constraint validation API to check if a field is valid and display custom message via JavaScript.
• Removed the placeholder fields from the solution as it is not a ux consideration when it comes to usability.
• Add a11y aria tags that will read out validation messages when a field is invalid. Only tested with windows narrator.
• Used fluid types and spaces with Utopia, This is a reason why solution is overflowing. It's more readable but need to find a sweet spot.

As always any feedback to improve the solution is welcome. Thanks.
