手风琴背景图像的大小

Question

我用背景图像制作了一个水平手风琴，但与手风琴的宽度相比，图像相当大。我想让手风琴缩小背景图片，现在我只能看到每个背景图片的中心。

这是我的代码：(样本)

.accordion {
  width: 100%;
  max-width: 1080px;
  height: 400px;
  overflow: hidden;
  margin: 50px auto;
}
.accordion ul {
  width: 100%;
  display: table;
  table-layout: fixed;
  margin: 0;
  padding: 0;
}
.accordion ul li {
  display: table-cell;
  vertical-align: bottom;
  position: relative;
  width: 16.666%;
  height: 400px;
  background-repeat: no-repeat;
  background-position: center center;
  transition: all 500ms ease;
}
.accordion ul li:nth-child(1) {

Answer 1

由于您目前正在使用图像作为背景，因此您现在可以使用方便的 CSS 属性。

MDN - 背景尺寸：Contain：

该关键字指定背景图片在保证其两个尺寸小于或等于背景定位区域对应尺寸的情况下尽可能放大。

Answer 2

尝试为您的图像设置固定宽度以查看完整图像，而不仅仅是图像的中心。

参见 fiddle。

如果你要用大图，我最好用 background-size:cover 代替。
