获得祖父母的宽度

Question

我想获得祖父母的宽度而不是父母的宽度。用css可以吗？

这是我的html和css：

＆＃13;

＆＃13;

.outter {
  position: relative;
  width: 100%;  // In my case is 900px
  overflow: hidden;
  height: 250px;
}
.inner {
  position: absolute;
  top: 0px;
  left: 0px;
  right: 0px;
  width: 1000%; // In my case is 9000px
  height: inherit;
  transition: left 0.5s ease;
}
.outter .inner div {
  float: left;
  width: 50%; //How to get 450px instead of 4500px 
}

＆＃13;

<div class="outter">
  <div class="inner">
    <div>One</div>
    <div>Two</div>
    <div>Three</div>
  </div>
</div>

＆＃13;
