我是这个网站的新手，我对编码也很陌生。我正在尝试制作非画布菜单，但遇到了三个小问题。首先，如何在菜单展开后更改其宽度？其次，如何使三行菜单按钮位于屏幕右侧而不是左侧？第三，如何在鼠标悬停时打开的可扩展画布菜单中添加子菜单？

我将 html 和 css 代码放入 Jsfiddle：https ://jsfiddle.net/ghbx6fmn

/*=====  SLIDE MENU  ======*/

/*----------  HIDE SELECT CHECKBOX  ----------*/

.toggle, 
.full-screen-close
{
	display: none;
}

.full-screen-close
{
	width: 100%;
	height: 100%;
	position: absolute;
	cursor: pointer;
	top:0;
	left:0;
}

/*----------  TOGGLE OFF-CANVAS MENU  ----------*/

.toggle:checked + .container > .menu-container 
{
  	margin-left: 70%;
}

.toggle:checked + .container > .content .full-screen-close
{
  	display: block;
  	background: rgba(0,0,0,.5);
}

.menu
{
	padding-top: 24px;
}

.toggle-btn,
.close-btn
{
	cursor: pointer;
}

.toggle-btn
{
	font-size: 2.25rem;
}


.close-btn
{
	float: right;
	font-size: 1.5rem;
	padding: 1.5rem;
	color: #ededed;
}

.menu-container, 
.content
{
	transition: margin 0.5s ease-in-out;
}

.menu-container
{
	background: #2c3e50;
	width: 40%;
	margin-left: 100%;
	
	float: right;
	height: 100%;
	position: absolute;

	z-index:99;
}

.slide-menu i
{
	margin-right: 1rem;
	font-size: 1.5rem;

	vertical-align: middle;

.slide-menu li a
{
	color: #fff;
	padding: 1.5rem;

	font-size: 1.125rem;

	text-transform: uppercase;
	font-weight: 600;

	display: block;

	transition: background-color .5s ease-in-out;
}

.slide-menu li a:hover

	background-color: #34495e;

回答：

其次，如何使三行菜单按钮位于屏幕右侧而不是左侧？

...只是：

.toggle-btn {
    font-size: 2.25rem;
    position: absolute;
    right: 0;
}
