当我单击 SIGN UP 按钮时，为什么我的覆盖容器没有向左移动？

Question

这是我的代码盘链接：https://codepen.io/xaviour1504/pen/zYEzGLJ 当我尝试单击注册按钮时，只有登录部分向右移动，但覆盖容器部分没有向左移动。这是我的代码

    /* move overlay to left */
    .container.right-panel-active.overlay-container {
        transform: translateX(-100%);
    }

Answer 1

您没有正确选择叠加层。

用途：

.container.right-panel-active .overlay-container

也就是说，当设置了 right-panel-active 类时，将选择一个具有 overlay-container 类的子项（这就是空间的用途）。

Answer 2

尝试使用这些值：

/* move sign in to the right */
.container.right-panel-active .sign-in-container {
    transform: translateX(-100%);
}
/* move overlay to left */
.container.right-panel-active.overlay-container {
    transform: translateX(100%);
}

请看这里：

const signUpButton = document.getElementById('signUp');
const signInButton = document.getElementById('signIn');
const content = document.getElementById('container');

signUpButton.addEventListener('click', () =>
    content.classList.add('right-panel-active')
);

signInButton.addEventListener('click', () =>
    content.classList.remove('right-panel-active')
);
