Question

如何让导航栏中的单词居中？我希望将家庭，新闻和下拉列为中心。

/* Navbar container */

.navbar {
  overflow: hidden;
  background-color: #333;
  font-family: Arial;
}


/* Links inside the navbar */

.navbar a {
  float: left;
  font-size: 16px;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}


/* The dropdown container */

.dropdown {
  float: left;
  overflow: hidden;
}


/* Dropdown button */

.dropdown .dropbtn {
  font-size: 16px;
  border: none;
  outline: none;
  color: white;
  padding: 14px 16px;
  background-color: inherit;
}


/* Add a red background color to navbar links on hover */

.navbar a:hover,
.dropdown:hover .dropbtn {
  background-color: red;
}


/* Dropdown content (hidden by default) */

.dropdown-content {
  display: none;
  position: absolute;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}


/* Links inside the dropdown */

.dropdown-content a {
  float: none;
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}


/* Add a grey background color to dropdown links on hover */

.dropdown-content a:hover {
  background-color: #ddd;
}


/* Show the dropdown menu on hover */

.dropdown:hover .dropdown-content {
  display: block;
}

Answer 1

您可以使用另一个答案中提到的flexbox。另一个选项是删除导航栏项目上的float属性，然后添加display: inline-block。然后通过将text-align: center添加到navbar

来中心所有内容

/* Navbar container */

.navbar {
  overflow: hidden;
  background-color: #333;
  font-family: Arial;
  text-align: center;
}


/* Links inside the navbar */

.navbar a {
  display: inline-block;
  font-size: 16px;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}


/* The dropdown container */

.dropdown {
  display: inline-block;
}


/* Dropdown button */

.dropdown .dropbtn {
  font-size: 16px;
  border: none;
  outline: none;
  color: white;
  padding: 14px 16px;
  background-color: inherit;
}


/* Add a red background color to navbar links on hover */

.navbar a:hover,
.dropdown:hover .dropbtn {
  background-color: red;
}


/* Dropdown content (hidden by default) */

.dropdown-content {
  display: none;
  position: absolute;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}


/* Links inside the dropdown */

.dropdown-content a {
  float: none;
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}


/* Add a grey background color to dropdown links on hover */

.dropdown-content a:hover {
  background-color: #ddd;
}


/* Show the dropdown menu on hover */

.dropdown:hover .dropdown-content {
  display: block;
}

您可以将以下内容添加到.navbar：

justify-content: center;
