The blocks are at a different distance, my script switches them via transform: translate. But when you go through the fields through the tab button, he switches them to the same incorrect. How to prevent it when you click on the tab to move to the hidden div? display: none. Don't to offer. :)

You can do it by javascript,
Disable tab press on submit button of first form
like this
$('#first button[type=submit]').keydown(function(objEvent) {
if (objEvent.keyCode == 9) { //tab pressed
objEvent.preventDefault(); // stops its action
}
})
