如何用CSS更改滚动条位置？

Question

有没有办法用CSS从左到右或从下到上改变滚动条的位置？

Answer 1

仅使用CSS:

右/左翻折:工作小提琴

.Container
{
    height: 200px;
    overflow-x: auto;
}
.Content
{
    height: 300px;
}

.Flipped
{
    direction: rtl;
}
.Content
{
    direction: ltr;
}

顶部/底部翻转:工作小提琴

.Container
{
    width: 200px;
    overflow-y: auto;
}
.Content
{
    width: 300px;
}

.Flipped, .Flipped .Content
{
    transform:rotateX(180deg);
    -ms-transform:rotateX(180deg); /* IE 9 */
    -webkit-transform:rotateX(180deg); /* Safari and Chrome */
}

Answer 2

这里是另一种方式，通过rotating element与scrollbar用于180deg,包装它content变成另一种元素，而rotating这wrapper对-180deg。检查下面的片段

div {
  display: inline-block;
  width: 100px;
  height: 100px;
  border: 2px solid black;
  margin: 15px;
}
#vertical {
  direction: rtl;
  overflow-y: scroll;
  overflow-x: hidden;
  background: gold;
}
#vertical p {
  direction: ltr;
  margin-bottom: 0;
}
#horizontal {
  direction: rtl;
  transform: rotate(180deg);
  overflow-y: hidden;
  overflow-x: scroll;
  background: tomato;
  padding-top: 30px;
}
#horizontal span {
  direction: ltr;
  display: inline-block;
  transform: rotate(-180deg);
}
