Question

我正在使用bootstrap从头开始创建一个网站，这是我第一次使用bootstrap，所以我可能做错了。

我正在尝试为3个内容列中的每一个实现单独的滚动面板，当滚动显示但灰显但无法正常工作时，它似乎不起作用

我使用stackoverflow html app贴了下面的代码，但是有些元素没有正确显示所以here是到目前为止完全正常工作的网站的链接

＆＃13;

body {
  padding-top: 159px;
  overflow: hidden;
}

html {
  overflow: hidden;
}

#navbar_right {}

.container {}

#categorias {
  background-color: #171717;
  overflow: scroll;
  height: 100%;
}

#content {
  background-color: #ffffff;
}

.btn {
  border-radius: 0;
}

.cat {
  margin: 10% 0% 10% 15%;
  position: relative;
  z-index: 1;
}

#right-bar {
}


/* Menu Top Navbar */

.button {
  position: relative;
  background-color: inherit;
  border: none;
  font-size: 16px;
  font-family: Roboto;
  color: #ffffff;
  padding: 20px;
  width: 200px;
  text-align: center;
  -webkit-transition-duration: 0.4s;
  /* Safari */
  transition-duration: 0.4s;
  text-decoration: none;
  overflow: hidden;
  cursor: pointer;
  outline: 0;
  -webkit-filter: grayscale(100%);
  filter: grayscale(100%);
}

.button:hover {
  -webkit-filter: grayscale(0%);
  filter: grayscale(0%);
}

.button:after {
  content: "";
  background: #ffffff;
  display: block;
  position: absolute;
  padding-top: 300%;
  padding-left: 350%;
  margin-left: -20px!important;
  margin-top: -120%;
  opacity: 0;
  transition: all 0.8s
}

.button:active:after {
  padding: 0;
  margin: 0;
  opacity: 1;
  transition: 0s
}

Answer 1

我认为问题是#categorias列的高度设置为100％，您应该给出一个特定的高度。尝试类似：

#categorias {
  height: 400px 
}

每个列的单独滚动面板，引导程序无法正常工作
