html - 无法将水平滚动捕捉更改为垂直滚动捕捉

Question

我找到了这个codepen ，但它是水平的。当我试图使其垂直时，它不起作用。

Pen我在以下位置找到了代码:

// None!

/* Hide the scroll bars */

body {
  overflow-y: hidden;
}

.slides {
  /* We set the scroll snapping */
  scroll-snap-type: x mandatory;
  /* Necessary for mobile scrolling */
  -webkit-overflow-scrolling: touch;
  /* For layout purposes */
  display: flex;
  /* To allow horizontal scrolling */
  overflow-x: scroll;
}

section {
  /* For styling purposes */
  height: 100vh;
  min-width: 100vw;
  display: flex;
  align-items: center;
  justify-content: center;
  background-repeat: no-repeat;
  background-size: cover;
  /* Set where the snapping should happen */
  scroll-snap-align: start;
}


/* Styling for the sections */

section h2 {

我尝试将所有 x 更改为 y，将所有 y 更改为 x，以及不同的组合，但我仍然找不到解决方案。

您的父元素没有固定的高度，并且会扩展以适合子元素。除此之外，您还需要为父元素设置 overflow-y:scroll; :

// None!

/* Hide the scroll bars */

body {
  margin: 0;
  padding: 0;
  overflow-x: hidden;
}

.slides {
  /* We set the scroll snapping */
  scroll-snap-type: y mandatory;
  /* Necessary for mobile scrolling */
  -webkit-overflow-scrolling: touch;
  display: flex;
  flex-flow: column;
  /* hide horizontal overflow */
  overflow-x: hidden;
  /* allow vertical overflow */
  overflow-y: scroll;
  /* set the height for parent, overwise it will expand to fit children */
  height: 100vh;
}

section {
  /* For styling purposes */
  display: flex;
  min-height: 100vh;
  width: 100vw;
  align-items: center;
  justify-content: center;
  background-repeat: no-repeat;
  background-size: cover;
  /* Set where the snapping should happen */
  scroll-snap-align: start;
}


/* Styling for the sections */

section h2 {
  font-family: system-ui, sans-serif;
  font-size: 2rem;
  color: #1a1a1a;

}

section h3 {
  font-family: system-ui, sans-serif;

添加其他 CSS 属性只是为了美观，请随意忽略。
