我正在尝试将黑盒垂直和水平居中！对于水平居中，我已经尝试过margin: auto，但它不适用于高分辨率。

我正在努力让我的英雄区域做出响应。当我减小窗口的宽度时，黑框会居中，但在高宽度时它会保持在左侧。

另外请帮我把它水平对齐！还请帮助我调整我的背景！

因此，我的问题是：-

  1. 我想将黑盒垂直和水平居中！
  2. 帮助我调整红色背景以使其响应

对齐元素最可靠的方法是使用 CSS3 表格布局。欲了解更多信息，请阅读这篇文章。

在下面的代码中，我使用了这种技术。查看它如何在全屏模式和调整窗口大小时运行。我还修复了您的背景以适合整个页面大小，将“立即预订！”中的文本居中 按钮并使文本对齐（更漂亮）。

body {
  margin: 0;
  }

#header{
	width: 100%;
	height: 100px;
	background: rgba(0,0,0,0.7);
}

#heroarea{
    width: 100%;
	height: calc(100vh - 100px);
	background-color:red;
}

.container {
    display: table;
	width: 100%;  
    height: 100%;  
}

.container > span {
    display: table-cell;
    text-align: center;
    vertical-align: middle;
}

#hero-intro-box{
	background: rgba(0,0,0,0.8);
	width: 100%;
	max-width: 800px;
	height: auto;
	border: 1px solid white;
	border-radius: 15px;
	padding: 10px 10px 30px 10px;
}

#hero-intro-box h1{
	color: white;
	text-align: center;
	padding-top: 3%;
}

#hero-intro-box p{
	color: white;
	margin: 15px;
	padding: 3%;
	padding-top: 2%;
    text-align: justify;
}

#hero-intro-box #book-now-button{
    display: table;
	height: 50px;
	width: 150px;
	background: rgba(255,255,255,0.5);
	text-align: center;
	border-radius: 15px;
	border: 2px solid darkgrey;
    margin: 0 auto;
}

#book-now-button > span{
  display: table-cell;
  text-align: center;
  vertical-align: middle;
}

@media (max-width: 400px) {
	#heroarea{
		height: 600px;

	#hero-intro-box{
		height: auto;
		margin-bottom: 30px;
