Question

尽管我在导航切换按钮上遇到了一些问题，但我仍尝试在Twitter引导程序上进行工作，以使网站响应迅速，但我已将所有库包括在内，这是此处所提出的一些问题的问题，我仍然无法知道确切的问题。

body {
  font-family: Arial, serif;
  background: url(https://freenaturestock.s3.us-east-1.amazonaws.com/1602.jpg) center center no-repeat;
  background-attachment: fixed;
  background-size: cover;
}


/* editing the logo part*/

.logo {
  height: 32px;
  opacity: 1;
}


/*  editing the navbar background colour*/

.navbar-inverse {
  background: rgba(0, 0, 0, 0.5);
}


/* navbar list options editing*/

.nav li {
  color: #fff;
  font-size: 17px;
  margin-right: 15px;
  padding: 10px 15px;
}

.nav li:hover {
  border-bottom: 3px solid #00FFB8;
  padding-bottom: 3px;
}

Answer 1

您遇到两个问题，第一个出现在导航栏的id中，其中包含一个空格：

id="myNavbar ">

必须为：id="myNavbar">

第二个问题是您包括旧的jQuery版本（有错误，并且两次？）

body {
  font-family: Arial, serif;
  background: url(https://freenaturestock.s3.us-east-1.amazonaws.com/1602.jpg) center center no-repeat;
  background-attachment: fixed;
  background-size: cover;
}


/* editing the logo part*/

.logo {
  height: 32px;
  opacity: 1;
}


/*  editing the navbar background colour*/

.navbar-inverse {
  background: rgba(0, 0, 0, 0.5);
}


/* navbar list options editing*/

.nav li {
  color: #fff;
  font-size: 17px;
  margin-right: 15px;
  padding: 10px 15px;
}

.nav li:hover {
  border-bottom: 3px solid #00FFB8;
  padding-bottom: 3px;
}

      </div>

    </nav>
  </div>
</body>
