css中的全宽菜单

标签： javascript html css

我已经在网络上创建了一个菜单代码，它很棒，但我希望我的菜单具有响应性和全宽度但我是css和html的新手 这是菜单css代码

  .menu, .menu ul {
  list-style: none;
  padding: 0;
  margin: 10;
  max-width: 100%;
  width:100%;
}
.menu {
  height: 58px;
  max-width: 100%;
}
.menu li {
  background: -moz-linear-gradient(#292929, #252525);

它是菜单的HTML代码

下面，

.menu li {
    background: -moz-linear-gradient(#292929, #252525);
    background: -ms-linear-gradient(#292929, #252525);
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #292929), color-stop(100%, #252525));
    background: -webkit-linear-gradient(#292929, #252525);
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#292929', endColorstr='#252525');
    background: -o-linear-gradient(#292929, #252525);
    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='#292929', endColorstr='#252525')";
    background: linear-gradient(#292929, #252525);
    border-bottom: 2px solid #181818;
    border-top: 2px solid #303030;
    min-width: 180px;
}

改变这个：

min-width: 180px;

为：

min-width: calc(100%/5);

其中5是菜单项的数量，必须根据菜单项进行更改。
