如果您只想在一个子页面上更改它，您必须在任何父元素的某处添加一个类或id，并从那里写入选择器 那一页就可以了
<body class="foo">
如果在页面中观察到body类，则会为该页面抛出一个唯一的类。 将body class作为ul li的参考，您将设置页边距底部的样式：0， 至于乙二醇 HTML:
希望我正确理解了你的问题。您想将ul>li类更改为marginbottom:25px；但仅适用于给定页面。然后这应该可以工作。创建另一个类，并将其添加到要控制下页边距的元素中，然后添加到另一个类。如果只想影响单个页面，请仅将一个类放在该页面的父元素的某个位置，然后使用包含该类的选择器，例如foo page ul li{margin bottom:0；}您可以控制html代码吗？@SahilDhir这次，我在同一页面中使用了脚本样式和一些函数jQuery。您可以显示该页面的代码吗？如果有其他li元素需要保留其底部边距，该怎么办？一个有效的答案，但可能太严格了@AndyHolmesOmg，我太困惑了。我需要什么样的答案@在这种情况下，page类和ul li所在的主div将是最好的。@DikaAndharu我将使用此解决方案，但将类应用于ul元素，而不是整个body元素，或者Eugene的答案-这两个概念本质上是相同的：现在是真正的解决方案；。在您的解决方案中不需要ul.row，因为您已经明确地瞄准了一个IDY，您仍然不需要在CSS中说ul。身份证在保险单上
