以下 HTML 代码，我搞不定，丢给 GPT4 也搞不定，由于 title 和 sendbox 高度固定的，如何让 chat-container 自动填充 right 的剩余高度，再让 chat-container 的内容会超出当前高度时自动显示滚动条，我已经尽力了，chat-container 依然还是被撑破高度，向各位大佬请教了

上面定高 h1 ，下面定高 h2

中间高度是 calc(100% - [h1+h2]px)
不要用 flex

听我的，chat-container 的 flex: 1 改成 flex: 1 1 0 ，并去掉 display: flex

经测试，在 bottom 加上 display: flex;height: 100%;，就能正常了
