Bootstrap容器横向有两种形式。将鼠标悬停在 Form1 上将增加宽度并减少 form2 的宽度。但逆转并没有发生。请提出任何建议。

请看下图。当悬停在绿色表格上时,表格从左到右移动,橙色表格减小宽度,绿色表格增加宽度,但当悬停在橙色表格(反向)上时不会发生这种情况。

基本上我正在尝试实现像 THIS 这样的形式

最佳答案

您可以使用 flexbox 来做到这一点。正如 Selva 所提到的,CSS 只能选择下一个兄弟,而不能选择前一个。然而,使用 flexbox 这要容易得多:

.flexible{display: flex; flex-direction: row;}
#form1:hover{
width: 100%;
}
#form2:hover{
width: 100%;
}
