Question

我正在为自己创建一个网站，并且正在按照编解码器的教程进行操作，当我完成时，我注意到按钮是不可点击的，因为当你点击时，下拉菜单就会消失。请帮忙？提前谢谢。

适合我。我认为你没有正确地包含mixins。由于您没有将它们包含在上面的代码段中，因此我转到了教程链接并手动包含它们。尝试检查顶部sass文件中是否包含mixin，如教程中所示。确保您的文件名匹配，并且您的mixins匹配。

你的sass应该转换为这个css。注意，我调整了颜色，你应该可以从这里拿走：

.nav-main {
  width: 100%;
  background-color: grey;
  height: 70px;
  color: white;
}
.nav-main .logo {
  float: left;
  height: 40px;
  padding: 15px 30px;
  font-size: 1.4em;
  line-height: 40px;
}
.nav-main > ul {
  margin: 0;
  padding: 0;
  list-style-type: none;
  float: left;
}
.nav-main > ul > li {
  float: left;
}

.nav-item {
  display: inline-block;
  padding: 15px 20px;
  height: 40px;
  line-height: 40px;
  color: pink;
  text-decoration: none;
}
.nav-item:hover {
  background: orange;
}

.nav-drop:focus {
  background-color: orange;
}
.nav-drop:focus ~ .nav-content {
  max-height: 400px;
  transition: max-height, 0.4s, ease-in;
}

.nav-content {
  margin-left: 345px;
  position: absolute;
  top: 70px;
  overflow: hidden;
  background-color: orange;
  max-height: 0;
}
.nav-content a {
  color: blue;
  text-decoration: none;
}
.nav-content a:hover {
  text-decoration: underline;
}

.nav-sub {
  padding: 20px;
}
.nav-sub ul {
  margin: 0;
  padding: 0;
  list-style-type: none;
}
.nav-sub ul a {
  display: inline-block;
}
