Question

我有以下导航栏。我想在导航栏的最左侧移动它的登录/注册组件，但无法找到方法。可能的解决方案是什么，我在登录li元素上尝试了padding-left：0，但这似乎不起作用。任何帮助都将不胜感激

HTML：

＆＃13;

body {
  margin: 0;
  background: #222;
  font-weight: 300;
  background-image: url('bg.jpeg');
}

header {
  background: #d9c2ac;
  position: relative;
}

header::after {
  content: '';
  display: table;
  clear: both;
}

nav {
  float: left;
}

nav ul {
  margin: 0;
  padding: 0;
  list-style: none;
}

nav li {
  display: inline-block;
  margin-left: 70px;
  padding-top: 30px;
  position: relative;
}

nav ul li a {
  color: #444;
  text-decoration: none;
  text-transform: uppercase;
  font-size: 14px;
  font-weight: bold;
}

nav a:hover {}

nav a::before {
  content: '';
  display: block;
  height: 5px;
  width: 0%;
  background-color: #444;
  transition: all ease-in-out 500ms;
}

nav a:hover::before {
  width: 100%;
}

form .form {
  float: right;
}

.search-bar {
  float: right;
}

ul li:last-child {
  position: absolute;
  right: 0;
  bottom: 0;
  margin: 15px;
  margin-bottom: 0px;
  padding: 0;
}

＆＃13;

<body>

  </header>

Answer 1

您可以使用伪css来对齐项目。

nav li:first-child {
  margin-left: 0;
}

您可以查看here

Answer 2

使用rm-auto将边距设置为0

.navbar-tan
{
  background-color:tan;
}

  </ul>
</nav>

Answer 3

尝试在此处使用 Flexbox ...并使用margin实用程序来对齐第一个和最后一个项...

...将margin-right:auto应用于第一个元素以将其对齐最左侧角落

...并将margin-left:auto应用于最后一个元素以使其最右边对齐..

我也更改了你的一些css并删除了所有float值。此处也不需要在搜索框中使用position:absolute。
