Question

1），我按照W3schools的sticky navbar header教程进行了操作，并尝试在演示网站的首页上对其进行幻灯片播放。（对于幻灯片，我还遵循了W3schools tutorial。）

我注意到，每当向下滚动查看内容时，幻灯片放映总是会重叠并位于粘性导航栏标题的顶部。

2）另外，如何将链接置于粘性标题中？我尝试做left: 35%; position: relative;使其居中一些，但它没有完全居中。（该代码在CSS部分的#navbar a下进行了注释。）

谢谢您的帮助！

我的代码：

/* Navbar */
.logo {
  height: 10%;
  width: 15%;
  display: block;
  margin-left: auto;
  margin-right: auto;
}

#navbar {
  overflow: hidden;
  background-color: #333;
}

#navbar a {
  margin-left: auto;
  margin-right: auto;
  color: gold;
  font-family: "League Spartan";
  text-transform: uppercase;
  float: left;
  display: block;
  padding: 2rem;
  /* left: 35%;
  position: relative; */
}

#navbar a:hover {
  color: black;
  background-color: #ddd;
}

.content {
  padding: 16px;
}

.sticky {
  position: fixed;
  top: 0;
  width: 100%;
}

.sticky + .content {
  padding-top: 60px;
}

/* Slideshow */
.slideshow-container {
  max-width: 1000px;
  position: relative;
  margin: auto;
}

.mySlides {
  display: none;
}

.prev,
.next {
  cursor: pointer;
  position: absolute;
  top: 50%;
  width: auto;
  margin-top: -22px;
  padding: 16px;
  color: white;
  font-weight: bold;
  font-size: 18px;
  transition: 0.6s ease;
  border-radius: 0 3px 3px 0;
  user-select: none;
}

.next {
  right: 0;
  border-radius: 3px 0 0 3px;
}

.prev:hover,
.next:hover {
  background-color: rgba(0, 0, 0, 0.8);
}

.text {
  color: #f2f2f2;
  font-family: "League Spartan";
  font-size: 15px;
  text-transform: uppercase;
  padding: 8px 12px;
  position: absolute;
  bottom: 8px;
  width: 100%;
  text-align: center;
}

.numbertext {
  color: #f2f2f2;
  font-family: "League Spartan";
  font-size: 12px;
  padding: 8px 12px;
  position: absolute;
  top: 0;
}

.dot {
  cursor: pointer;
  height: 15px;
  width: 15px;
  margin: 0 2px;
  background-color: #bbb;
  border-radius: 50%;
  display: inline-block;
  transition: background-color 0.6s ease;
}

.active,
.dot:hover {
  background-color: #717171;
}

.fade {
  -webkit-animation-name: fade;
  -webkit-animation-duration: 1.5s;
  animation-name: fade;
  animation-duration: 1.5s;
}

@-webkit-keyframes fade {
  from {
    opacity: 0.4;
  }
  to {
    opacity: 1;
  }
}

@keyframes fade {
  from {
    opacity: 0.4;
  }
  to {
    opacity: 1;
  }
}
