html - 如何在 bootstrap 中将图像居中放置在 2 列上

转载作者：行者123 更新时间：2023-11-28 02:25:47

我想创建一个分屏 Bootstrap 4 页面，并将图像放在与两列重叠的中心。我创建了两个相等的列，但我不知道如何放置图像以使其重叠。

我已经尝试了 position:absolute 和 float:left 但它没有帮助。感谢您的帮助!

html,
body {
  height: 100%;

}

col {
  height: 100vh;
}

img {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
}
