在我的 class 那就是容器流体中,我可以对顶部和底部进行填充,但它对右侧和左侧不起作用?

In my class thats container-fluid, I can do padding for top and bottom, but it doesn't work for right and left?

我正在使用 bootstrap-5。我找不到解决方案。这怎么能适用于顶部和底部,而不适用于右侧和左侧?你能帮我么?好的,默认情况下,bootstrap 可能有一个值,但我正在 css 上更改它。所以我认为我在那里写的东西一定有用。我怎样才能让它发挥作用?

#title {
  background-color: #ff4c68;
}

.container-fluid {
  padding: 3% 15%;
}

h1 {
  font-family: 'Montserrat', sans-serif;
  line-height: 1.5;
  font-size: 3rem;
}

尝试bootstrap类例如m-1,px-1,m-2等...

<div class="container-fluid px-1 py-3"> 

.container-fluid {
    padding: 3% 15% !important;
}

这是因为CSS没有覆盖默认的bootstrap css..

所以使用下面给出的代码并覆盖

#title {
  background-color: #ff4c68;
}

.container-fluid {
  padding: 3% 15% !important;
}

h1 {
  font-family: 'Montserrat', sans-serif;
  line-height: 1.5;
  font-size: 3rem;

您的代码将在 bootstrap 版本 4 中运行。我猜您看过 Angela Yu 的网络训练营只是添加 !important css 没有覆盖默认值 css

.container-fluid{
  padding: 3% 15% !important;
  }
