html - 为什么我的左右栏不可滚动

Question

我在 column-fluid container 中有一个三列。我的右列和左列是固定的，但不可滚动，尽管我放置了 overflow-y:scroll

.row > .sidebar-fixed {
    position: relative;
    top: 0;
    left:auto;
    width: 220px;
    overflow-y:scroll;
}

.left {
    float:left;
}

.right {
    float:right;
}

.fixed-fixed {
    margin: 0 240px;
}

如何使我的左右栏可垂直滚动。

Answer 1

滚动条显示为禁用，因为没有要滚动的内容。

我改变了你的 CSS...

.row > .sidebar-fixed{
    position: absolute;
    top: 0;
    width: 220px;
  height: 100%;
    overflow-y:scroll;
}
.row > .sidebar-fixed.left{
    left:0;
}
.row > .sidebar-fixed.right{
    right:0;
}

.fixed-fixed {
    margin: 0 240px;
}

...添加填充文本...

  <div class="well sidebar-fixed left">
    <p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo. Quisque sit amet est et sapien ullamcorper pharetra. Vestibulum erat wisi, condimentum sed, commodo vitae, ornare sit amet, wisi. Aenean fermentum, elit eget tincidunt condimentum, eros ipsum rutrum orci, sagittis tempus lacus enim ac dui. Donec non enim in turpis pulvinar facilisis. Ut felis. Praesent dapibus, neque id cursus faucibus, tortor neque egestas augue, eu vulputate magna eros eu erat. Aliquam erat volutpat. Nam dui mi, tincidunt quis, accumsan porttitor, facilisis luctus, metus</p>
  </div><!--/.well -->
