You can use the scrollTop function and an if statement to check against a variable such as the element height or position from the top.
https://api.jquery.com/scrollTop/
$(document).scroll(function() {
var scroll = $(this).scrollTop();
if (scroll > x) {
}
});

I wrote this jquery to add the class 'snap' to a navigation bar when you scrolled past the top of the container (#container) containing the nav bar. In this case, my 'snap' class gives my navigation a fixed position (relative to the body) so it'll stick to the top of the screen.
If you use this code, you can change #container for the id of the block that comes after your sign up form. What I would do next is hide your navbar maybe {top:-200px;}? by default and then add a class to it ('snap' - or whatever is semantically meaningful for you) to make it appear {top:0;}.
