Question

我正在尝试用Bootstrap 4建立一个练习网站（这是我第一次使用它）。我想出了我正在设计的布局问题，它可能非常简单，但是我无法解决它。

<div id="box-container" class="container-fluid">
    <div id="box-row" class="row">
        <div id="header-box1" class="col-lg-6 header-box">
        </div>
        <div id="header-box2" class="col-lg-6 header-box">
        </div>
    </div>
</div>

Full demo | Full code（忽略图像，它们只是占位符）

查看完整演示，你会发现我有2个盒子，我已经放置了缩放悬停效果。左框正好如何工作，但右框与左边重叠。我知道这很简单，但我无法绕过它。

有什么建议吗？干杯

Answer 1

您正在寻找修改背景尺寸。

.header-box {
    background-position: center;
    background-size:100%;
    transition: all 1s ease;
    -moz-transition: all 1s ease;
    -ms-transition: all 1s ease;
    -webkit-transition: all 1s ease;
    -o-transition: all 1s ease;
}
.header-box:hover{
    background-size:150%;
    -ms-filter: "progid:DXImageTransform.Microsoft.Matrix(M11=1.5, M12=0, M21=0, M22=1.5, SizingMethod='auto expand')"; /* IE8 */
    filter: progid:DXImageTransform.Microsoft.Matrix(M11=1.5, M12=0, M21=0, M22=1.5, SizingMethod='auto expand'); /* IE6 and 7 */ 
}

将带有背景的div移动到bootstrap col元素中，在bootstrap cols上设置overflow: hidden;，然后将框元素设置为position: absolute; top: 0; left: 0; right: 0; bottom: 0;

#header-box1 {
  background-image: url(http://indianapublicmedia.org/arts/files/2012/04/sample-gates-9-940x626.jpg);
}

#header-box2 {
  background-image: url(http://indianapublicmedia.org/arts/files/2012/04/sample-gates-9-940x626.jpg);
}

#box-row {
  height: 250px; /* you don't need to modify this */
  overflow: hidden;
  box-sizing: border-box;
}

.header-box {
  background-position: center;
  transition: all 1s ease;
  -moz-transition: all 1s ease;
  -ms-transition: all 1s ease;
  -webkit-transition: transform 1s ease;
  -o-transition: all 1s ease;
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
}

.header-box:hover {
  transform: scale(1.5);
  -moz-transform: scale(1.5);
  -webkit-transform: scale(1.5);
  -o-transform: scale(1.5);
  -ms-transform: scale(1.5);
  -ms-filter: "progid:DXImageTransform.Microsoft.Matrix(M11=1.5, M12=0, M21=0, M22=1.5, SizingMethod='auto expand')";
  filter: progid: DXImageTransform.Microsoft.Matrix(M11=1.5, M12=0, M21=0, M22=1.5, SizingMethod='auto expand');
}

#box-row > .col-lg-6 {
  overflow: hidden;
}

Answer 3

将每个图像的Div放在他们自己的另一个div中，并将overflow设置为none。确保外部div的z-index更高。
