jQuery Content滑块阻止响应式菜单抽屉

Question

The content slider blocks the menu items of my responsive site

我使用以下css来完成此操作

<header role="banner">
    <div id="cd-logo"><a href="#0"><img src="img/cd-logo.svg" alt="logo" onClick="#"></a></div>
      <nav class="main-nav">
			<ul><!-- insert more links here -->
                <li><a class="cd-signin" href="#0">Sign in</a></li>
				<li><a class="cd-signup" href="#0">Sign up</a></li>
			</ul>
		</nav>
	</header>

以下是滑块的html

/* -------------------------------- 

Main components 

-------------------------------- */
header[role=banner] {
  position: relative;
  height: 50px;
  background: #343642;
}
header[role=banner] #cd-logo {
  float: left;
  margin: 4px 0 0 5%;
  /* reduce logo size on mobile and make sure it is left aligned with the transform-origin property */
  -webkit-transform-origin: 0 50%;
  -moz-transform-origin: 0 50%;
  -ms-transform-origin: 0 50%;
  -o-transform-origin: 0 50%;
  transform-origin: 0 50%;
  -webkit-transform: scale(0.8);
  -moz-transform: scale(0.8);
  -ms-transform: scale(0.8);
  -o-transform: scale(0.8);
  transform: scale(0.8);
}
header[role=banner] #cd-logo img {
  display: block;
}
header[role=banner]::after {
  /* clearfix */
  content: '';
  display: table;
  clear: both;
}
@media only screen and (min-width: 768px) {
  header[role=banner] {
    height: 80px;
  }
  header[role=banner] #cd-logo {
    margin: 20px 0 0 5%;
    -webkit-transform: scale(1);
    -moz-transform: scale(1);
    -ms-transform: scale(1);
    -o-transform: scale(1);
    transform: scale(1);
	z-index:inherit;
  }
}

.main-nav {
  float: right;
  margin-right: 5%;
  width: 44px;
  height: 100%;
  background: url("../img/cd-icon-menu.svg") no-repeat center center;
  cursor: pointer;
}
.main-nav ul {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  -webkit-transform: translateY(-100%);
  -moz-transform: translateY(-100%);
  -ms-transform: translateY(-100%);
  -o-transform: translateY(-100%);
  transform: translateY(-100%);
}
.main-nav ul.is-visible {
  -webkit-transform: translateY(50px);
  -moz-transform: translateY(50px);
  -ms-transform: translateY(50px);
  -o-transform: translateY(50px);
  transform: translateY(50px);
}
.main-nav a {
  display: block;
  height: 50px;
  line-height: 50px;
  padding-left: 5%;
  background: #292a34;
  border-top: 1px solid #3b3d4b;
  color: #FFF;
}
@media only screen and (min-width: 768px) {
  .main-nav {
    width: auto;
    height: auto;
    background: none;
    cursor: auto;
  }
  .main-nav ul {
    position: static;
    width: auto;
    -webkit-transform: translateY(0);
    -moz-transform: translateY(0);
    -ms-transform: translateY(0);

    line-height: 80px;
  }
  .main-nav ul.is-visible {

    -moz-transform: translateY(0);
    -ms-transform: translateY(0);
    -o-transform: translateY(0);
    transform: translateY(0);
  }
  .main-nav li {
    display: inline-block;
    margin-left: 1em;
  }
  .main-nav li:nth-last-child(2) {
    margin-left: 2em;
  }
  .main-nav a {
    display: inline-block;
    height: auto;
    line-height: normal;
    background: transparent;
  }
  .main-nav a.cd-signin, .main-nav a.cd-signup {
    padding: .6em 1em;
    border: 1px solid rgba(255, 255, 255, 0.6);
    border-radius: 50em;
  }
  .main-nav a.cd-signup {
    background: #2f889a;
    border: none;
  }
}

这是菜单抽屉的html

{{1}}

及其相应的CSS

{{1}}

任何人都可以帮助我吗？

滑块位于标题上方，因为它具有更高的z-index值。只需为标题指定更高的z-index值：

.header {
  ...
  z-index: 10;
}
