我正在尝试创建一个小型聊天客户端以插入我的网站，并且无法将已折叠的div与其底部的div对齐。< / p>
我有一个div，其中有两个聊天窗口（也是div s） - 默认情况下两个窗口都已最大化。
当我最小化其中一个窗口时，面板向上折叠，位于容器div的顶部。
当两者都被最小化时，它可以根据需要工作，页面底部有两个最小化条。
我粘贴图片，但我是stackoverflow的新手，无法发布图片。
当内部的另一个div未最小化时，如何将折叠的div强制到容器的底部？
可以在这里看到：
以下是代码：

只需在第二个.chatblah div中添加一个修复类，然后使用此css
.chatblah.fix {
position: absolute;
right: 290px;
}

您可以使用flexbox并使用flex-direction: column;和justify-content: flex-end;将聊天元素与底部对齐。
.chat-container {
bottom: 0;
right: 0;
position: fixed;
/* height: 500px; */
max-height: 500px;
/* border: 1px solid blue; */
display: flex;
flex-direction: row;
}
.chatblah {
flex: 1;
display: flex;
flex-direction: column;
justify-content: flex-end;
}
