导航背景透明度问题

Question

我遇到的问题是我的下拉菜单背景有些透明，我能够看到菜单后面页面上的文字。如果这有任何不同，我也在使用博客。

这是我在此图片中的问题

这是我的代码＆＃34;

<div style="text-align: left;">

Answer 1

请为以下ID添加background-color属性。

#mbt-menu {
    font: bold 13px 'Trebuchet MS', Arial, sans-serif;
    text-decoration: none;
    text-shadow: 0 0px 0 #000;
    background-color: /*your color code*/;
}

Answer 2

在您的css代码中添加/更新以下条目。

#mbt-menu ul li, #mbt-menu>li li a {
    background-color: #ffffff;
}

同时删除以下宽度属性。由于ul元素的固定宽度

导致问题

#mbt-menu ul a{
    /*Other styles*/
    width:130px;
    /*Other styles*/
}
