Question

我试图仅使用html和css在链接中创建图像。有许多元素需要＆＃34;堆叠＆＃34;彼此重叠。

我很难理解继承，嵌套等等。这是我到目前为止编写的代码：

＆＃13;

.heart {
  position: relative;
  margin-top: 20px;
  background-color: #000000;
  opacity: .8;
  width: 65px;
  height: 30px;
  border-radius: 15px;
  display: inline;
}
.box {
  margin: 75px auto;
  position: relative;
  height: 490px;
  width: 700px;
  background-color: #18a0ff;
  box-shadow: 1px 15px 50px 2px;
  display: flex;
}
.thumbnail_image {
  position: absolute;
  float: left;
  display: inline-block;
  top: 0px;
  left: 0px;
}
.text_container {
  top: 60px;
  left: 200px;
  right: 100px;
  width: 400px;
  height: 338px;
  position: relative;
  display: flex;
}
h1 {
  font-color: #ffffff !important;
  text-transform: uppercase;
  font-size: 60px;
  font-family: Montserrat;
  font-weight: 700;
  line-height: 1.1;
  text-align: left;
}

＆＃13;

<div class="box">
  <div class="heart">
  </div>
  <div class="thumbnail_image">
    <img src="http://res.cloudinary.com/dp32vpqfu/image/upload/v1457298445/Sheldon_Pic_l3cprk.jpg">
  </div>
  <div class="text_container">
    <h1>Don't You think that if I were wrong, &nbsp;&nbsp; &nbsp; I'd know it?</h1>
  </div>
</div>

＆＃13;

我关心的是如何正确放置心脏对话框，文本容器和图像叠加层。我似乎误解了正确的继承语法或结构。

Answer 1

在心形对话框，文本容器和图像叠加元素上使用position:absolute;，然后使用left和right属性正确定位它们。

Answer 2

绝对定位 和 z-index 是使用HTML和CSS堆叠图片所涉及的关键词。

我继续用一些html / css模拟你的图像，让你了解实现。

Z-index在这个特定的例子中是不相关的，因为你只需要在基数上方有一层，这是自动给你绝对定位的，但是如果你有多个层，你需要将z-index设置为a数字值，其中较低编号的z索引显示在底部，较高的z索引显示在顶部。

这是我的代码，希望它有所帮助：

＆＃13;

body {
  background-color: grey;
}

.container {
  position:fixed;
  height: 500px;
  width: 700px;
  background-image: url(http://i.stack.imgur.com/MS8X8.png);
  background-position: 46% 52%;
  background-size: 150%
}

.hearts {
  position: absolute;
  background-color: rgba(149, 165, 166,.5);
  color: white;
  right: 40px;
  top: 15px;
  padding: 15px 25px 15px 25px;
  border-radius: 15px
}


.blue {

  width: 550px;
  height: 500px;
  background-color: rgb(102,173,255);
  float: right;

}

h1, h5 {

font-size: 60px;
}

#attr {
  left: 200px;
  top: 450px;
}

Answer 4

了解堆叠顺序

在您的情况下，自然堆叠顺序将完成工作;这很好地解释了over on the MDN。要理解的主要内容是元素将与标记中的元素重叠。用一个简单的例子可以更好地解释这一点：

＆＃13;

div {
  position: absolute;
  background: red;
  height: 100px;
  width: 100px;
  top: 0;
  left: 0;
}
.two {
  background: blue;
  top: 10px;
  left: 20px;
}
.three {
  background: green;
  top: 20px;
  left: 40px;
}

＆＃13;

<div class="one">1</div>
<div class="two">2</div>
<div class="three">3</div>

＆＃13;

有了这个......

让我们做这些！

在这个答案结尾处随意跳转到完整的例子！

想要使用一些迂腐的语义吗？

一个<blockquote> element将所有内容组合在一个语义容器中。
包含后退和前进导航的<nav> element
包含所引用人姓名的<cite> element

我们的标记现在看起来像这样：

<blockquote>
    <p>Don't You think that if I were wrong, I'd know it?</p>

    <cite>Sheldon Cooper</cite> 

    <a href="#" class="love-counter">
      <3 123
    </a>  

    <nav>
      <a href="#">Previous</a> 
      <a href="#">Next</a>
    </nav>
</blockquote>

CSS

主要背景图像和颜色

这些可以作为blockquote本身的背景。您可以使用background-size确保图片始终具有相同的尺寸。（这显然会扭曲尺寸不正确的图像）

blockquote {    
    background: #18a0ff url(image-url) no-repeat;
    background-size: 170px 490px;
}

添加透明灰色背景和引号字符

这可以使用绝对定位的before pseudo-element of blockquote添加。使用left / right / bottom拉伸元素以及与图像匹配的宽度。透明的灰色叠加层和透明文字由rgba color提供。

blockquote:before {
  content: '\201C';
  position: absolute;
  left: 0;
  top: 0;
  bottom: 0;
  padding-top: 30px;
  font-size: 2.4em;
  text-align: center;
  background: rgba(0,0,0,0.7);
  width: 170px;
  color: rgba(255,255,255,0.3);
}

将主引文文本与其引文对齐

为了合并较小的引号，可以更直观地使主文本垂直居中。我们可以使用display: flex property和justify-content来轻松实现这一目标; the flex-direction: column property将主引号叠加在引文的顶部。块引用也被赋予左右填充以适当地水平定位。

blockquote {
  display: flex; 
  justify-content: center;
  flex-direction: column;
  padding: 0 140px 0 200px;
}

定位后退/前进导航和爱情计数器

可以使用position: absolute以及相应的left / right / bottom / top属性轻松找到这些内容。它们看起来像这样：

.love-counter {
  position: absolute;
  right: 20px;
  top:  20px;
}

nav {
  position: absolute;
  left: 0px;
  bottom: 20px;
}

完整示例

兼容性： IE 11+ and all modern browsers.

您可能会考虑a javascript method缩小较大引号的字体大小。
