顶部菜单 - 将一个项目右对齐

Question

我想将 "Login" 项目右对齐。我对 HTML 和 CSS 很陌生。我什至不知道这是否是创建水平菜单栏的正确方法。像这样：How I want it to be

这是我的代码：

HTML:

@import url("FONTS/stylesheet.css");
body {
    font-family: 'Roboto', sans-serif;
}

.topnav {
    background-color: #333;
    overflow: hidden;
}

.topnav a {
    display: inline-block;
    color: #f2f2f2;
    padding: 14px 16px;
    text-decoration: none;
    font-size: 17px;
}

.topnav a:hover {
    background: #ddd;
    color: black;
}

/* Add a color to the active/current link */
.topnav a.active {
    background-color: #4CAF50;
    color: white;
}

<!DOCTYPE html>
<html>
<link rel="stylesheet" type="text/css" href="css/style1.css">
<link href="https://fonts.googleapis.com/css?family=Roboto" rel="stylesheet">
<body>

<div class="topnav">
  <a class="active" href="#home">Home</a>
  <a href="#projects">Projects</a>
  <a href="#contact">Contact</a>
  <a class="loginnav" href="#login">Login</a>
</div>

</body>
</html>

我需要改变什么？非常感谢！

Answer 1

将.topnav更改为display: flex，并将margin-left: auto;添加到.loginnav:

body {
  font-family: 'Roboto', sans-serif;
}

.topnav {
  display: flex;
  background-color: #333;
  overflow: hidden;
}

.topnav a {
  display: inline-block;
  color: #f2f2f2;
  padding: 14px 16px;
  text-decoration: none;
  font-size: 17px;
}

.topnav a:hover {
  background: #ddd;
  color: black;
}

.topnav a.active {
  background-color: #4CAF50;
  color: white;
}

.loginnav {
  margin-left: auto;
}

<div class="topnav">
  <a class="active" href="#home">Home</a>
  <a href="#projects">Projects</a>
  <a href="#contact">Contact</a>
  <a class="loginnav" href="#login">Login</a>
</div>

Answer 2

您只需将此代码添加到您的 CSS 中即可 .topnav .loginnav {float:right;}

@import url("FONTS/stylesheet.css");
body {
    font-family: 'Roboto', sans-serif;
}

.topnav {
    background-color: #333;
    overflow: hidden;
}

.topnav a {
    display: inline-block;
    color: #f2f2f2;
    padding: 14px 16px;
    text-decoration: none;
    font-size: 17px;
}


.topnav a:hover {
    background: #ddd;
    color: black;
}

/* Add a color to the active/current link */
.topnav a.active {
    background-color: #4CAF50;
    color: white;
}
.topnav .loginnav {
    float: right;
}

<!DOCTYPE html>
<html>

<link rel="stylesheet" type="text/css" href="css/style1.css">
<link href="https://fonts.googleapis.com/css?family=Roboto" rel="stylesheet">

<body>

<div class="topnav">
  <a class="active" href="#home">Home</a>
  <a href="#projects">Projects</a>
  <a href="#contact">Contact</a>
  <a class="loginnav" href="#login">Login</a>
</div>

</body>
</html>

只需将其添加到您的代码中即可。

    .loginnav{
        margin-left:800px;
    }

Answer 4

你可以简单地用 flex 和 auto margin 从左边登录：

body {
    font-family: 'Roboto', sans-serif;
}

.topnav {
    background-color: #333;
    overflow: hidden;
    display: flex;
}

.topnav a {
    color: #f2f2f2;
    padding: 14px 16px;
    text-decoration: none;
    font-size: 17px;
}

.loginnav {
    margin-left: auto
}

.topnav a:hover {
    background: #ddd;
    color: black;
}

/* Add a color to the active/current link */
.topnav a.active {
    background-color: #4CAF50;
    color: white;
}

<!DOCTYPE html>
<html>

<link rel="stylesheet" type="text/css" href="css/style1.css">
<link href="https://fonts.googleapis.com/css?family=Roboto" rel="stylesheet">

<body>

<div class="topnav">
  <a class="active" href="#home">Home</a>
  <a href="#projects">Projects</a>
  <a href="#contact">Contact</a>
  <a class="loginnav" href="#login">Login</a>
</div>

</body>
</html>

请注意，我从 a 标签中删除了 inline-block 并向 .topnav 添加了规则 display: flex;

首先，将其显示为 flex，然后将这些项目对齐到末尾。

试试这个：

@import url("FONTS/stylesheet.css");
body {
    font-family: 'Roboto', sans-serif;
}

.topnav {
    background-color: #333;
    overflow: hidden;
}

.topnav a {
    display: inline-block;
    color: #f2f2f2;
    padding: 14px 16px;
    text-decoration: none;
    font-size: 17px;
}

.topnav a:hover {
    background: #ddd;
    color: black;
}

/* Add a color to the active/current link */
.topnav a.active {
    background-color: #4CAF50;
    color: white;
}

.right {
position: absolute;

top: 8px;
right: 8px;
}

<!DOCTYPE html>
<html>
<link rel="stylesheet" type="text/css" href="css/style1.css">
<link href="https://fonts.googleapis.com/css?family=Roboto" rel="stylesheet">
<body>

<div class="topnav">
  <div class="left">
  <a class="active" href="#home">Home</a>
  <a href="#projects">Projects</a>
  <a href="#contact">Contact</a>
  </div>
  <div class="right">
  <a class="loginnav" href="#login">Login</a>
  </div>
</div>

</body>
</html>

这可能是个糟糕的方法，但它确实有效！
