拜托，可以帮我一个人吗？

Answer 1

我不确定我完全理解你的意思。

本节适用于submenu：

 #submenu li{
    background: url(ImagensCSS/nav-bg.png) repeat-x 0px 4px;
    height: 69px;
    margin:0;
    padding:0;
    display:block;
}

如果您希望项目之间的空间更少，请将高度更改为39px（例如）。那是你在找什么？

Answer 2

你有身高问题。更改这些代码;

#cssmenu ul li a {
    height: 20px;
}

#cssmenu ul li a {
    height: 20px;
}

#cssmenu ul li a:hover, #cssmenu ul li.active a {
    height: 15px;
}

Answer 3

尝试这种风格。我希望这就是你要找的东西。

#cssmenu ul li {
display: inline-block;
float: left;
list-style: outside none none;
}

Answer 4

我认为这个空间来自a上边缘。尝试将其设置为零。

#cssmenu ul li a {
    display: block;
    height: 37px;
    padding: 22px 30px 0;
    margin: 0px 2px 0; /* <- set top margin to zero */
    border-radius: 2px 2px 0 0;
    text-decoration: none;
    font-size: 15px;
    color: white;
    text-shadow: 0 1px 1px rgba(0, 0, 0, 0.75);
    font-weight: 400;
    opacity: .9;
}

对于水平菜单，您可以将sub ul position设置为absolute并将其子项设置为向左浮动

#cssmenu li:hover ul {
    display: block;
    position: absolute; /* set it to absolute  */
}
#cssmenu li:hover li {
    float: left; /* set floating to display inline  */
    top: 0;
}
