javascript - 从列表标签和表格标签中删除 HTML 中的空白

Question

我已经搜索了几个在线资源和 tutorials，以删除 Javascript 菜单和它正下方的图像之间的空白。我什至从代码中物理删除了空格，但无济于事

Answer 1

尝试将此添加到您的 CSS 中，看看它是否有所不同并删除空格:

ul, li { margin:0 !important; padding:0 !important; }

如果是这样，这只是将边距或填充设置为您需要的问题。

要注意的另一件事是这些元素的行高。尝试:

ul, li { line-height: 100%: }

要查看的实时示例页面会很好。
