作为javascript开发，简述css什么是外边距重叠？重叠的结果是什么？
外边距重叠是CSS中的一种现象，它发生在两个或更多元素的外边距之间。当两个或更多的元素具有相同的外边距，并且这些外边距位于元素的相同方向时，这些外边距将重叠。 重叠的结果可能会导致元素的位置和布局发生改变。例如，如果两个元素的外边距重叠，那么这两个元素之间的距离可能会比预期的要小。这是因为重叠的外边距被计算在元素的总宽度或高度中，从而减少了元素之间的空间。 为了避免外边距重叠，我们可以使用一些CSS技巧，例如设置元素的浮动属性、使用display属性、使用负外边距等。 [2023-11-09 01:07:12 | AI写代码神器 | 145点数解答]
