Responsive Ping coming soon page using flexbox

Used JS to provide feedback for invalid email fields. The inbuilt js email validator (which uses the html validator) does not check for name@host.domain. Instead it just checks for name@host. Thus used a custom email validator function rather than just using the inbuilt checkValidity() function. Also to use tailwind css classes in JS, we need to add the location of js file in the content section of the tailwind.config.js. Had missed doing this initially

Tried to use semantic html and maintain accessibility for input fields, links and buttons.

Feedback is welcome.
