CSS

Question

如果没有滚动条，我将无法使用导航滚动条。

我在这里找到了很多示例，但它们不起作用。

我累了 parent class 溢出：隐藏；和 child class 与 overflow-y: auto;

有人知道我的 CSS 出了什么问题吗？

Answer 1

你可以试试这个隐藏滚动条。

::-webkit-scrollbar {
    display: none;
}

Answer 2

您只需添加一些 padding-right 即可隐藏滚动条。

html, body {
  background-color: #111111;
  width: 100%;
  height: 100%;
  padding: 0;
  margin: 0;
  color: #fff;
  font : 12px Arial,Courier New,Tahoma;
}

.layoutWrapper {
  width: 100%;
  height: 100%;
  display: flex;
}

.layoutHead {
  width: 100%;
  height: 200px;
  background-color: #171616;
  color: #444;
  line-height: 200px;
  font-size: 100px;
  text-align: center;
}

.layoutNav {
  background-color: #333333;
  width: 250px;
  height: 100%;
  overflow: hidden;
}

.layoutNavWrapper {
  width: 250px;
  height: 100%;
    padding-right: 15px; /* added */
  overflow-y: scroll;
}

.layoutNavWrapper ul {
  width: 240px;
  padding: 0;
  margin: 0 0 0 5px;
}

.layoutNavWrapper ul li {
  width: 240px;
  height: 40px;
  line-height: 40px;
  margin: 5px 0 0 0;
  list-style-type: none;
}

.layoutNavWrapper ul li a {

  text-decoration: none;
  display: block;
  width: 220px;
  height: 40px;

Answer 3

这是以前的回答：Hide scroll bar, but while still being able to scroll。

为了解决你的问题，我对上面的答案进行了调整：

.layoutNav {
  background-color: #333333;
  width: 250px;
  height: 100%;
        overflow: hidden;
}

.layoutNavWrapper {
  width: 250px;
  height: 100%;
  overflow-y: scroll;
        overflow-x: hidden;
        padding-right: 17px; /* Increase/decrease this value for cross-browser compatibility */
}

这是一个有效的 pen。

Answer 4

对于 Firefox 量程： .your-class{ scrollbar-color: transparent transparent; }

对于 Safari，Chrome： ::-webkit-scrollbar { display: none; }
