如何摆脱下拉菜单上的额外空间？

时间：2016-05-12 13:33:29

标签： html css

所以我在悬停时创建了一个带有下拉菜单的导航栏，但问题是列表中的项目在左侧获得了一些额外的padding，而不是在哪里可以删除{ {1}}（我试过检查但找不到任何东西）。

这是问题所在： PROBLEM

这就是我想要的： HOW IT SHOULD BE

代码：

padding

* {
    margin: 0px;
    border: 0px;
}


/*Header*/

header {
    position: relative;
    background-image: url(../img/forheader.png);
    background-size: cover;
}

.logo {
    background: rgba(224, 228, 40, 0.7);
    padding: 2.5%;

即可重置

nav ul li ul已弃用，因此不使用

答案 1 :(得分：0)

只需在样式表中添加.unfixed ul {padding-left:0;}即可从下拉菜单左侧删除默认的40px填充。
