Answer 1

添加以下 CSS：

.nav > li > a:focus, .nav > li > a:hover{

  background: transparent !important;

}

var Deb = [];

$.noConflict();

jQuery(document).ready(function($) {

  Deb.push(document.location);

});

/*add*/

.nav>li>a:focus,

.nav>li>a:hover {

  background: transparent!important;

}

body {

  margin: 0;

  padding: 0;

  font: 400 14px/24px 'Open Sans', sans-serif;

}

#header {

  float: left;

  width: 100%;

  position: relative;

}

.head-top {

  float: left;

  width: 100%;

  position: fixed;

  background: red;

  z-index: 999;

}

#nav {

  margin: 16px 0 0 0;

  list-style: none;

}

#nav li {

Answer 2

在最后添加这个

/* unvisited link */

a:link {

  background-color: red !important;

}

/* visited link */

a:visited {

  background-color: red !important;

}

/* mouse over link */

a:hover {

  background-color: red !important;

}

/* selected link */

a:active {

  background-color: red !important;

}
