我想垂直對齊容器 div 的三個 div，但是容器內的所有 3 個 div 都是浮動的，一個在右邊，一個在中間，一個在左邊，以制作導航欄。
我在 bootstrap 中看到了所有導航欄，我想將 3 個導航欄 div 放入一個 div 中以制作導航欄。
我是 HTML 代碼的初學者，所以我希望大家能幫助我。

使用彈性盒
#container{
display:flex;
flex-direction:column;
align-items:center;
width:100%;
height:30vh;
justify-content:space-evenly;
}
div{
border:solid 2px red;
width:25%;
text-align:center;
}<div id='container'>
<div>a</div>
<div>b</div>
<div>c</div>

對于所有神圣事物的熱愛，完全不需要漂浮物。它們既陳舊又麻煩，并且對 Bootstrap 布局系統的整個想法感到厭惡。任何建議它們的教程都應該被忽略。
此外，您似乎在這里重新創建輪子。這一切都是開箱即用的。
這是門票：
- 根據檔案，使用適當的容器/行/列結構。
- 把班級
align-items-center放在一排。這垂直對齊內容。 - 將課程
flex-fill放在選單欄上。這讓它占用了所有可用空間。我還將 class 應用于justify-content-end導航元素以使其標簽正確對齊。
注意...絕對不需要自定義 CSS。
