我正在使用flex:0 0 auto；在CSS和一些瀏覽器中，div之間有1px的差距。

body {
    overflow: hidden;
    position: relative;
    height: 100vh;
    width: 100vw;
    background-color: black;
}

.scrollWrapper {
    position: relative;
    overflow-x: hidden;
    overflow-y: scroll;
    display: flex;
    flex-direction: column;
    height: 100%;
    width: 100%;
}

.scrollWrapper > * {
    background-color: white;
    height: 10%;
    width: 100%;
    flex: 0 0 auto;
}

<div class="scrollWrapper">
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
</div>
