Javascript help for a page protected by a password

Hello,

I am building a website where people can access the content if they know the code to enter the website.
Here it is : http://interplayx.webflow.io/

Right now I just used a form but I am sure that by using a bit of Jquery I should be able to check that the password entered is correct and the trigger an animation if the form submission is a “success”

(I don’t care if the password appears in the source code of the webpage)

Thanks for your help!
