<meta charset=utf-8 />
<title></title>
<style>
body, html {
height: 100%;
margin: 0;
font-family: Arial, Helvetica, sans-serif;
}
* {
box-sizing: border-box;
}
.bg-image {
/* 所使用的图像 */
background-image: url("001.jpg");
/* 添加模糊效果 */
filter: blur(8px);
-webkit-filter: blur(8px);
/* 完整的高度 */
height: 100%;
/* 中心和缩放图像*/
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
/* 将文本放置在页面/图像的中间 */
.bg-text {
background-color: rgb(0,0,0);
background-color: rgba(0,0,0, 0.4);
color: white;
font-weight: bold;
border: 3px solid #f1f1f1;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
z-index: 2;
width: 80%;
padding: 20px;
text-align: center;
}
</style>
</head>
<body>
<div class="bg-image"></div>
<div class="bg-text">
<h2 id="欢迎来到">欢迎来到</h2>
<h1 id="虚拟现实">虚拟现实</h1>
<p>一切都是虚拟的，但感觉还是真实</p>
</div>
</body>
</html>The effect is as shown below:
（ The background image comes from the Internet, sorry for the infringement)
How about it! Isn’t the effect great!
So in the above code, I will introduce you to several key css attributes:
filter The attribute defines the visibility of the element (usually ) Effects (e.g. blur and saturation).
Note: The non-standard "filter" attribute supported by older versions of Internet Explorer (4.0 to 8.0) has been deprecated. IE8 and lower browsers usually use the opacity attribute.
transformThe property applies a 2D or 3D transformation to the element. This property allows us to rotate, scale, move or tilt the element.
borderShorthand property sets all border properties in one declaration.
border-width：规定边框的宽度。 border-style：规定边框的样式。 border-color：规定边框的颜色。 inherit：规定应该从父元素继承 border 属性的设置。
backgroundShorthand property sets all background properties in one declaration.
background-color：规定要使用的背景颜色。 background-position：规定背景图像的位置。 background-size：规定背景图片的尺寸。 background-repeat：规定如何重复背景图像。 background-origin：规定背景图片的定位区域。 background-clip：规定背景的绘制区域。 background-attachment：规定背景图像是否固定或者随着页面的其余部分滚动。 background-image：规定要使用的背景图像。 inherit：规定应该从父元素继承 background 属性的设置。
