scroll-padding-inline-start
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2021年9月.
scroll-padding-inline-start 属性定义了滚动口的最优视区——用于在用户视野中放置内容的目标区域——的行首内边距。作者由此得以排除滚动口被其他内容（如固定定位的工具栏或侧边栏）所遮挡的区域，或在目标元素与滚动口的边之间留出更多余地。
尝试一下
scroll-padding-inline-start: 0; scroll-padding-inline-start: 20px; scroll-padding-inline-start: 2em; <section class="default-example" id="default-example"> <div class="scroller" id="example-element"> <div>1</div> <div>2</div> <div>3</div> </div> <div class="info">Scroll »</div> </section> .default-example { flex-wrap: wrap; } .default-example .info { width: 100%; padding: 0.5em 0; font-size: 90%; } .scroller { text-align: left; width: 250px; height: 250px; overflow-x: scroll; display: flex; box-sizing: border-box; border: 1px solid black; scroll-snap-type: x mandatory; } .scroller > div { flex: 0 0 250px; width: 250px; background-color: rebeccapurple; color: #fff; font-size: 30px; display: flex; align-items: center; justify-content: center; scroll-snap-align: start; } .scroller > div:nth-child(even) { background-color: #fff; color: rebeccapurple; } 语法
