如何移动<li>里面的小箭头图片？

代码如下：

body {

  padding: 0;
}
nav {
  width: 100%;
  background: #f1f1f1;
  padding: 5px;
}
nav ul {
  list-style-type: none;
}
nav ul li {
  display: inline-block;
}
nav ul li a img {
  max-width: 20px;
  height: auto;
  margin-left: 4px;
}
nav ul li a {
  color: #636363;
  padding: 10px;

nav ul li a:hover {
  color: #333;
  text-decoration: underline;

        <li><a href="#">Guaranties</a>
        </li>
        <li><a href="#">Contacts</a>
        </li>
      </ul>
    </nav>
  </header>

如果我只是将 margin-top 添加到 img 元素，它会将所有 ul 向下移动。那不是我想要的。我想将其向下移动一点以与 li 项

对齐

Answer 1

vertical-align: middle; 可能就是您所需要的。

body {
  margin: 0;
  padding: 0;
}
nav {
  width: 100%;
  background: #f1f1f1;
  padding: 5px;
}
nav ul {
  list-style-type: none;
}
nav ul li {
  display: inline-block;
}
nav ul li a img {
  max-width: 20px;
  height: auto;
  margin-left: 4px;
  vertical-align: middle;
}
nav ul li a {
  color: #636363;
  padding: 10px;
  text-decoration: none;
}
nav ul li a:hover {
  color: #333;
  text-decoration: underline;
}

Answer 2

您可以将图片设置为绝对位置。

nav ul li a img {
  position:absolute;
  max-width: 20px;
  height: auto;
  margin-left: 4px;
}

然后你可以使用顶部定位它属性，虽然不漂亮但很有效
