你能告诉我如何去除红线和导航栏之间的白色间隙吗?CSS:

    /* Main */
#menu{
width: 100%;
margin: 0;
padding: 10px 0 0 0;
list-style: none;
background: #111;
background: -moz-linear-gradient(#444, #111);

我在 CSS 底部添加了代码,但这似乎没有太大区别

最佳答案

使用 CSS,有很多选择。
你可以试试

hr { 
margin-botton: 0;
}

或者不使用 hr,您可以向菜单添加一些填充,并为其添加顶部边框。调整大小并添加填充以获得所需的效果。

#menu {
border-top: 1px solid red;
}
