html - 为什么这是垂直滚动而不是水平滚动？

Question

我试图让这段代码水平滚动，但由于某种原因它垂直滚动。将光标放在图像上并向下滚动以了解我的意思。

我怎样才能让它水平滚动呢？它有溢出 x 作为滚动。因此，所有图像都将位于同一行，而不是像现在这样的 2 行。

#images-wrap {
  width: 100%;
  height: auto;
  margin-top: 25px;
  float: left;
  position: relative;

  position: static;
}
#main-image {
  width: 80.5%;
  float: left;
  background-size: cover !important;
  background-position: center center !important;
  height: auto;
  padding-bottom: 53.666%;

  width: 100%;
  padding-bottom: 66.666%;
}
#image-thumbs {
  width: 17.5%;
  height: auto;
  float: left;
  margin-left: 2%;
  overflow-y: auto !important;
  overflow-x: hidden;
  position: absolute;
  right: 0;
  height: 100%;

  width: 100%;
  margin-left: 0;
  position: absolute;
  height: auto;
  top: 0;
  left: 0;
}
.image-thumb {
  margin-bottom: 6px;
  background-position: center;
  background-size: cover;
  width: 100%;
  height: auto;
  padding-bottom: 66.666%;

  width: 25%;
  padding-bottom: 16.666%;
  float: left;
}

#test-ar {
  float: left;
  width: 100%;
  height: auto;
  padding-bottom: 16.666%;
  background: orange;
  position: relative;
  overflow-x: scroll;
  /* overflow-y: hidden; */
}

<div id="images-wrap">
  <div id='test-ar'>
    <div id="image-thumbs" style="overflow: hidden;">

不是 float 元素，而是对所有图像缩略图使用 display: inline-block，并使用 white-space: nowrap 将其父级设置为不包装内联元素.要删除各个图像缩略图之间的空白，您可以简单地注释掉该行:

#images-wrap {
  width: 100%;
  height: auto;
  margin-top: 25px;
  float: left;
}
#image-thumbs {
  height: auto;
  margin-left: 2%;
  right: 0;
  height: 100%;

  width: 100%;
  margin-left: 0;
  position: absolute;
  height: auto;
  top: 0;
  left: 0;
  
  overflow-x: scroll;
  white-space: nowrap;
}
.image-thumb {
  margin-bottom: 6px;
  background-position: center;
  background-size: cover;
  width: 100%;
  height: auto;
  padding-bottom: 66.666%;

  width: 25%;
  padding-bottom: 16.666%;
  display: inline-block;
}

#test-ar {
  width: 100%;
  padding-bottom: 16.666%;
  background: orange;
  position: relative;
  overflow-x: scroll;
}
