我添加了一个下拉导航，现在其他内容一直在下拉菜单中

Question

我在我的网站上添加了下拉导航。下拉菜单本身工作正常，但是当我向侧面添加新内容时，例如只有一些段落，新内容出现在下拉菜单中。我已经包含了代码，请给我任何反馈。我是 Web 开发的新手，所以不要太苛责我。

html{
    background: url(background.jpg) no-repeat center fixed;
    background-size: cover;
}
.title{
    display: inline-block;
    font-family: 'Permanent Marker', cursive;
    font-size: 25pt;
    color: black;
    padding-top: 2ch;
    padding-left: 3rem;
}

  

/* Dropdown Button */
.dropbtn {
  background-color: #000000;
  color: white;
  padding: 16px;
  font-size: 16px;
  border: none;
  float: right;
  display: flex;
  align-items: flex-end;
}

/* The container <div> - needed to position the dropdown content */
.dropdown {
  position: relative;
  float: right;
  padding-right: 2rem;
}

/* Dropdown Content (Hidden by Default) */
.dropdown-content {
  display: none;
  position: relative;
  background-color: #70868a;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
  z-index: 1;
  font-family: 'Roboto Condensed', sans-serif;
}

/* Links inside the dropdown */
.dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

/* Change color of dropdown links on hover */
.dropdown-content a:hover {background-color: #ddd;}

/* Show the dropdown menu on hover */
.dropdown:hover .dropdown-content {display: block;}

/* Change the background color of the dropdown button when the dropdown content is shown */
.dropdown:hover .dropbtn {background-color: black;}

.name{
  display: flex;
  justify-content: left;
  font-family: 'Roboto Condensed', sans-serif;
  padding-left: 3rem;
}

.moving-words{
  display: flex;
  align-self: center;
  justify-content: center;
  padding-top: 10rem;
  font-size: 35pt;
  font-family: 'Alfa Slab One', cursive;
  text-shadow: 5px 5px rgb(99, 151, 185);


}

您忘记关闭 divs 只需添加 </div></div>

检查代码段

而且页脚应该在 body 标签内而不是在外面。

html{
    background: url(background.jpg) no-repeat center fixed;
    background-size: cover;
}
.title{
    display: inline-block;
    font-family: 'Permanent Marker', cursive;
    font-size: 25pt;
    color: black;
    padding-top: 2ch;
    padding-left: 3rem;
}

  

/* Dropdown Button */
.dropbtn {
  background-color: #000000;
  color: white;
  padding: 16px;
  font-size: 16px;
  border: none;
  float: right;
  display: flex;
  align-items: flex-end;
}

/* The container <div> - needed to position the dropdown content */
.dropdown {
  position: relative;
  float: right;
  padding-right: 2rem;
}

/* Dropdown Content (Hidden by Default) */
.dropdown-content {
  display: none;
  position: relative;
  background-color: #70868a;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
  z-index: 1;
  font-family: 'Roboto Condensed', sans-serif;
}

/* Links inside the dropdown */
.dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

/* Change color of dropdown links on hover */
.dropdown-content a:hover {background-color: #ddd;}

/* Show the dropdown menu on hover */
.dropdown:hover .dropdown-content {display: block;}

/* Change the background color of the dropdown button when the dropdown content is shown */
.dropdown:hover .dropbtn {background-color: black;}

.name{

  justify-content: left;
  font-family: 'Roboto Condensed', sans-serif;
  padding-left: 3rem;
}

.moving-words{

  justify-content: center;
  padding-top: 10rem;
  font-size: 35pt;
  font-family: 'Alfa Slab One', cursive;
  text-shadow: 5px 5px rgb(99, 151, 185);
