CSS scroll-margin-left - 0

下面的示例演示如何使用scroll-margin-left: 0，这会导致左侧不设置边距各节的一侧 -

<html>
<head>
<style>
   .scroll-container {
      display: flex;
      width: 300px;
      height: 200px;
      overflow-x: scroll;
      overflow-y: hidden;
      scroll-snap-type: x mandatory;
   }
   .scrolling-section1,
   .scrolling-section2,
   .scrolling-section3 {
      flex: 0 0 auto;
      width: 300px;
      height: 200px;
      scroll-snap-align: start;
   }
   .scrolling-section1 {
      background-color: rgb(220, 235, 153);
      scroll-margin-left:0;
   }
   .scrolling-section2 {
      background-color: rgb(230, 173, 218);
      scroll-margin-left: 0;
   }
   .scrolling-section3 {
      background-color: rgb(119, 224, 210);
      scroll-margin-left: 0;
   }
</style>
</head>
<body>
   <h3>使用滚动条箭头滚动内容以查看效果。</h3>
   <div class="scroll-container">
      <div class="scrolling-section1">scroll-margin-left:0</div>
      <div class="scrolling-section2">scroll-margin-left: 0</div>
      <div class="scrolling-section3">scroll-margin-left: 0</div>
   </div>
</body>
</html>

CSS scroll-margin-left - 长度值

以下示例演示如何使用scroll-margin-left属性为每个节添加左边距，这向后滚动时会影响滚动行为 -

<html>
<head>
<style>
   .scroll-container {
      display: flex;
      width: 300px;
      height: 200px;
      overflow-x: scroll;
      overflow-y: hidden;
      scroll-snap-type: x mandatory;
   }
   .scrolling-section1,
   .scrolling-section2,
   .scrolling-section3 {
      flex: 0 0 auto;
      width: 300px;
      height: 200px;
      scroll-snap-align: start;
   }
   .scrolling-section1 {
      background-color: rgb(220, 235, 153);
      scroll-margin-left: 2em;
   }
   .scrolling-section2 {
      background-color: rgb(230, 173, 218);
      scroll-margin-left: 10px;
   }
   .scrolling-section3 {
      background-color: rgb(119, 224, 210);
      scroll-margin-left: 20px;
   }
</style>
</head>
<body>
   <h3>使用滚动条箭头反向滚动内容即可查看效果。</h3>
   <div class="scroll-container">
      <div class="scrolling-section1">scroll-margin-left: 2em</div>
      <div class="scrolling-section2">scroll-margin-left: 10px</div>
      <div class="scrolling-section3">scroll-margin-left: 20px</div>
   </div>
