I have a login jsp page where users can login in to my web application, I have also a sign Up form where user can register if they are not members. I'm trying to do the login and sign up forms in one JSP called login.jsp. Login part works fine However, I am unable to display the sign up form when a user clicks on the signup button. I've used the CSS from this tutorial


However, I am trying to implement the CSS in to login form and a signup form in to my JSP file I've downloaded all the CSS files required but for some reason the effects aren't taking place for when signup button is clicked

Here is the code for the login.jsp

<%@page import="java.util.Enumeration"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>

<!DOCTYPE html>
<!--[if lt IE 7 ]> <html lang="en" class="no-js ie6 lt8"> <![endif]-->

In the CSS file animate-custome I am hiding the second form by setting the opasity to 0 as follows

    z-index: 21;
    opacity: 0;

The login form has a z-index of 22 and therefore I've made the register form to have a z-index of 22 to put it under the login form.

So this is what should happen : when the Join us button is clicked , this should trigger the #toregister. the animation is done by using the sibling selector ~ to find the #register element.then I used use an animation called fadeInLeft. Since the form is hidden using zero opacity, I used an animation that fades in, to make it appear.

Here's the CSS code block where this animation take place:

    animation-duration: 0.5s;
    animation-timing-function: ease;
    animation-fill-mode: both;
@keyframes fadeInLeft {
    0% {
        opacity: 0;
        transform: translateX(-20px);

    100% {
        opacity: 1;
        transform: translateX(0);

THe first thing that comes to mind is that when you have some type of link or button on your screen, if you want it to open a popup or show a div, you have to prevent its default behavior since clicking on these types of elements will cause a post back by default.

Say you have an anchor elemnet that you want to use to show a div. Then you would do something like this in jQuery..


hi where is the best place to put this?

It was just an example. I'd have to really inspect your HTML to figure out the exact code and where to place it. I didnt have time for that today. sorry.

The point is that if you are using elements that cause a page to reload, you need to prevent that behavior so that you can show/unhide a div containing your signup form.
