导航栏切换按钮在单击时向右移动

Question

我在网页上有一个引导导航栏，它在右侧有一个切换按钮。但是当我点击它时，它会向右移动 10px，然后当它折叠时，它会向后移动。这看起来很奇怪。我试过 margin: 0 auto !important;在 CSS 中。但这会使切换按钮的位置居中。我希望我的切换按钮显示在右侧，并且不应该在点击时移动。

我在 navbar-brand 和切换按钮之间添加了很多 h3 标签，以使切换按钮显示正确。因为它没有以其他方式出现。

将此类 CSS 添加到您的代码中。

 button.navbar-toggler {
    float: right;
    padding: 10px;
    margin: 20px;
}
