无法将水平滚动捕捉更改为垂直滚动捕捉

Question

我找到了这个代码笔，但它是水平的。当我试图使它垂直时，它不起作用。

我在笔上找到了代码：

// 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;
}

我试着把所有的x改为y，把所有的y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，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;
}

其他css属性只是为了美观而添加的，可以随意忽略。
