汉堡菜单固定在右下角，引导程序

Question

我一直在寻找引导程序中移动菜单中的幻灯片，我能得到的最接近的是这个https://codepen.io/erikterwan/pen/EVzeRP , 但我不能让它从右到左打开并放入汉堡包右下角，有什么想法吗？

这将有点棘手，因为创建者写道：

可惜菜单必须在按钮内

但是，嘿，这是纯粹的 CSS 魔法。

要添加的代码是

/*
 * This move all the navbar to right because the ul is inside the button
 */
#menuToggle{
    position:fixed;
    left: calc(100vw - 70px);
    top:calc(100vh - 50px);
}

/*
 * This will position the menu
 */
#menu{
    top: calc(-100vh + 50px);
    left: 70px;
    margin: 0;
    margin-top: -100px;
    height: 100vh;
}

/*
 * Fade menu from the right
 */
#menuToggle input:checked ~ ul
{
    transform: translate(-100%, 0);
    opacity: 1;
}

/*
 * Correct the overflow
 */
 html{
     max-width: 100vw;
     overflow-x: hidden;
 }
