Question

我正在尝试使用Bootstrap创建导航栏。我尝试将ml-auto添加到按钮上，但没有执行任何操作。我希望汉堡图标在右边，但就在徽标旁边。

Answer 1

您的代码中A标记中的IMG标记未关闭。

<a href="#" class="navbar-brand"><img src="logo.png" width="300" height="60"</a>

应如下所示：

<a href="#" class="navbar-brand"><img src="logo.png" width="300" height="60"></a>

Answer 2

您不需要做任何事情，只是您的错误是您没有完成徽标图像标签>的丢失。因此它的页面结构不正确。请完成您的图片标签并尝试输入代码。

或者您也可以添加此代码段html代码。

@import url('https://fonts.googleapis.com/css?family=Montserrat:500&display=swap');

* {
  margin: 0px;
  padding: 0px;
  box-sizing: border-box;
}

li, a {
  font-family: "Montserrat", sans-serif;
  color: #edf0f1;
  text-decoration: none;
}

Answer 3

您忘记关闭徽标中的img标签。关闭它，它将修复它。

从

进行更改

<a href="#" class="navbar-brand"><img src="logo.png" width="300" height="60"</a>

到

<a href="#" class="navbar-brand"><img src="logo.png" width="300" height="60"></a>
