html - 如何重叠各种内容？

Question

目前我正在努力使我来自 .wrap-artist 的内容模糊地显示在背景图片上方。

CSS

.wrap-artwork {
    left: 0;
    right: 0;
    z-index: 1;
    display: block;
    background-image: url('https://i1.sndcdn.com/artworks-000183268921-teibnr-t500x500.jpg');
    background-size: cover;
    background-position:center;
    height: 150px;
    margin-bottom: 20px;
    margin-top: -1px;
    margin-right: -16px;
    margin-left: -16px;
    -webkit-filter: blur(8px);
    -moz-filter: blur(8px);
    -o-filter: blur(8px);
    -ms-filter: blur(8px);
    filter: blur(8px);
}

.wrap-artist {
    position: relative;
    left: 0;
    right: 0;
    z-index: 9999;
    margin-left: 20px;
    margin-right: 20px;
}

.container {
   margin-top: 25px;
   max-width: 100%;
   margin-left: auto;
   margin-right: auto;
   background-color: #ffffff;
   border: 1px solid #ddd;
   width: 1080px;
   overflow: hidden;
   padding-bottom: 25px;
}

我试过摆弄这些位置，但我使用的结构似乎根本不起作用。

HTML

<div class="container">
    <div class="wrap-artwork"></div>
        <div class="wrap-artist">
        this is our image content
        </div>
    <div class="col-md-8">
        some other content here     
    </div>

    <div class="col-md-4">
        finally some sidebar content here
    </div>
</div>

希望有人能帮助我，我用过this question指导我，但一定是错过了第一个答案中的某些内容。

    .wrap-artwork {
		left: 0;
		right: 0;
		z-index: 1;
		display: block;
		background-image: url('https://i1.sndcdn.com/artworks-000183268921-teibnr-t500x500.jpg');
		background-size: cover;
		background-position:center;
		height: 150px;
		margin-bottom: 20px;
		margin-top: -1px;
		margin-right: -16px;
		margin-left: -16px;
		-webkit-filter: blur(8px);
		-moz-filter: blur(8px);
		-o-filter: blur(8px);
		-ms-filter: blur(8px);
		filter: blur(8px);
	}
	
    .wrap-artist {
		position: relative;
		left: 0;
		right: 0;
		z-index: 9999;
		margin-left: 20px;
		margin-right: 20px;
    }

    .container {
       margin-top: 25px;
       max-width: 100%;
       margin-left: auto;
       margin-right: auto;
       background-color: #ffffff;
       border: 1px solid #ddd;
       width: 1080px;
       overflow: hidden;
       padding-bottom: 25px;
    }

<div class="container">
		<div class="wrap-artwork"></div>
			<div class="wrap-artist">
			this is our image content
			</div>
		<div class="col-md-8">
			some other content here		
		</div>
		
		<div class="col-md-4">
			finally some sidebar content here
		</div>
</div>

你想要这样的东西吗？ : See this fiddle

如果是这样，您必须将 relative 位置添加到 .container parent 并将 relative 位置替换为 absolute 在 .wrap-artist 类上使用 top 属性。

.wrap-artist {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    z-index: 9999;
    margin-left: 20px;
    margin-right: 20px;
}

.container {
   margin-top: 25px;
   max-width: 100%;
   margin-left: auto;
   margin-right: auto;
   background-color: #ffffff;
   border: 1px solid #ddd;
   width: 1080px;
   overflow: hidden;
   padding-bottom: 25px;
   position: relative;
}
