具有底层图像的两个单独的DIV不会浮动到右侧

问题描述 投票：0回答：2

我想将页面分成两半。一侧是带有蓝色透明覆盖层的计算机显示器的图像。当盘旋时，这将变得更亮。同样在右侧有不同的图像（音乐手稿）。但是，这在实践中不起作用，只是折叠到左侧的一个DIV块。

码：

html, body {
  background-color: black;
  height: 100%;
  width: 100%;
  margin: 0%;
}

div.leftImage {
  /*Set up positioning:*/
  display: block;
  float: left;
  width: 50%;
  height: 100%;
  z-index: 0;
  position: absolute;
  /*Set up the background:*/
  background-image: url("https://images.pexels.com/photos/270360/pexels-photo-270360.jpeg?w=940&h=650&dpr=2&auto=compress&cs=tinysrgb");
  background-position: 45%;
}

div.rightImage {
  /*Set up positioning:*/
  display: block;
  float: right;
  width: 50%;
  height: 100%;
  position: absolute;
  z-index: 0;
  /*Set up the background:*/
  background-image: url("https://upload.wikimedia.org/wikipedia/commons/9/9d/BWV605.png");
  background-position: center;
}

div.left {
  /*Set up positioning:*/
  display: block;
  float: left;
  width: 50%;
  height: 100%;
  position: absolute;
  z-index: 1;
  /*Set up the background:*/
  background-color: rgba(0, 150, 255, 0.5);
  transition: background-color 0.25s ease;
}

div.left:hover {
  background-color: rgba(0, 150, 255, 0.8);
}

div.right {
  /*Set up positioning:*/
  display: block;
  float: right;
  width: 50%;
  height: 100%;
  position: absolute;
  z-index: 1;
  /*Set up the background:*/
  background-color: rgba(204, 0, 0, 0.5);
  transition: background-color 0.25s ease;
}

div.right:hover {
  background-color: rgba(204, 0, 0, 0.8);
}
<!DOCTYPE html>

如果你正在使用position: absolute，像float: left这样的布局属性将没有任何效果。

相反，使用top，left，right和bottom属性来控制绝对定位的元素：

html, body {
  background-color: black;
  height: 100%;
  width: 100%;
  margin: 0%;
}

div.leftImage {
  /*Set up positioning:*/
  z-index: 0;
  position: absolute;
  top: 0;
  left: 0;
  right: 50%;
  bottom: 0;
  /*Set up the background:*/
  background-image: url("https://images.pexels.com/photos/270360/pexels-photo-270360.jpeg?w=940&h=650&dpr=2&auto=compress&cs=tinysrgb");
  background-position: 45%;
}

div.rightImage {
  /*Set up positioning:*/
  z-index: 0;
  position: absolute;
  top: 0;
  left: 50%;
  right: 0;
  bottom: 0;
  /*Set up the background:*/
  background-image: url("https://upload.wikimedia.org/wikipedia/commons/9/9d/BWV605.png");
  background-position: center;
}

div.left {
  /*Set up positioning:*/
  z-index: 1;
  position: absolute;
  top: 0;
  left: 0;
  right: 50%;
  bottom: 0;
  /*Set up the background:*/
  background-color: rgba(0, 150, 255, 0.5);
  transition: background-color 0.25s ease;
}

div.left:hover {
  background-color: rgba(0, 150, 255, 0.8);
}

div.right {
  /*Set up positioning:*/
  z-index: 1;
  position: absolute;
  top: 0;
  left: 50%;
  right: 0;
  bottom: 0;
  /*Set up the background:*/
  background-color: rgba(204, 0, 0, 0.5);
  transition: background-color 0.25s ease;
}

div.right:hover {
  background-color: rgba(204, 0, 0, 0.8);
}

只是另一个简单的替代方案，完全避免浮动。使用flexbox，您不需要浮动或定位元素。希望能帮助到你 ：）

html,
body {
  background-color: black;
  height: 100%;
  width: 100%;
  margin: 0;
}

.fc {
  display: flex;
  width: 100%;
  height: 100%;
}

.leftImage {
  width: 50%;
  background-image: url("https://images.pexels.com/photos/270360/pexels-photo-270360.jpeg?w=940&h=650&dpr=2&auto=compress&cs=tinysrgb");
  background-position: 45%;
}

.rightImage {
  width: 50%;
  background-image: url("https://upload.wikimedia.org/wikipedia/commons/9/9d/BWV605.png");
  background-position: center;
}

div.left {
  width: 50%;
  height: 100%;
  position: absolute;
  background-color: rgba(0, 150, 255, 0.5);
  transition: background-color 0.25s ease;
}

div.left:hover {
  background-color: rgba(0, 150, 255, 0.8);
}

div.right {
  width: 50%;
  height: 100%;
  position: absolute;
  background-color: rgba(204, 0, 0, 0.5);
  transition: background-color 0.25s ease;
}

div.right:hover {
  background-color: rgba(204, 0, 0, 0.8);
}


}
<div class="fc">
  <div class="leftImage">
    <div class="left">
      <p>Test.</p>
    </div>
  </div>
  <div class="rightImage">
    <div class="right">
      <p>Test.</p>
    </div>
  </div>
