Question

我有一个div，其中包含选项卡窗格。第一个选项卡窗格包含两个内部div。第一个内部div有一个搜索文本框，我想将其保留在固定位置，而我希望第二个内部div启用滚动。可行的代码如下：

这有效。但是，由于第二个内部div设置为520px（适用于我的笔记本电脑），所以当我在较大的屏幕上打开页面时，滚动窗口的高度在较小的屏幕上看起来很小，因此无法滚动。

我尝试使用100%将第二个内部div的高度设置为100vh，flex，direction as column。他们都没有帮助。

Answer 1

要设置尺寸以适合不同的屏幕尺寸，必须使用@media规则。请参阅此页面以了解它们是什么：https://www.w3schools.com/cssref/css3_pr_mediaquery.asp

Answer 2

也尝试在元标记中指定设备高度：

此：

<meta name="viewport" content="width=device-width, initial-scale=1">

成为这个：

<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1">

.sidebar {
  /* height:100%; - remove */
     min-height:100vh; /* - add */
}

将页面高度设置为滚动-当外部div隐藏时-内部div滚动
