Question

我已经在下面的链接Rezahttps://codepen.io/vsandeep2516/pen/XWbzPVa中编写了代码。问题是点击导航链接后出现白色补丁。

@sanriot 请参考截图

Answer 1

最后加上这个

/* 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;
}

Answer 2

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 {
  padding: 0;
  margin: 16px 0 0 0;
  list-style: none;
}

#nav li {
  display: inline-block;
  float: none;
  position: relative;
  padding: 0 0 20px 0;
}

#nav .active {
  background: transparent;
}

#nav li a {
  font: 400 14px/14px 'Lato', sans-serif;
  color: #000;
  text-transform: uppercase;
  text-decoration: none;
  padding: 0 20px;
  display: block;
  position: relative;
  z-index: 20;
}

#nav li:hover>a {
  background: none;
}

#nav li ul li a:hover,
#nav li ul li:hover>a {
  text-decoration: none;
}
