Question

我似乎无法将表单与放置在导航栏中的“input-sm”垂直对齐。如果表单的输入与导航栏的高度不同，则看起来它们是顶部对齐的。我希望有一种方法可以做到这一点，而无需手动调整填充或边缘顶部。有什么想法吗？

它看起来并不太糟糕，我只想弄明白该怎么做！

最简单的方法是调整边距，如上所述。这就是Bootstrap如何做到的。

.navbar-form {
    margin-top: 10px;
    margin-bottom: 10px;
}

第二个最简单的方法是使用flexbox，如果你能够这样做的话。

.navbar-form {
    display: flex;
    align-items: center;
}
/* Items will butt up next to each other using flexbox so the inline
spacing that existed before will be gone. So we replicate it. */
.navbar-form > .form-group {
    margin-right: 0.25rem;
}
