我目前已经开始在一个网站上玩跳棋，但我面临着在显示器上缩放的问题，在学校，我用笔记本电脑对网站进行编码，一旦我回到家在桌面上尝试，侧导航和主内容就错位了，看起来不像是被集成的样子。。。所以我只是困惑于该做什么以及如何保持它们的大小，无论是使用笔记本电脑还是台式机。
我试着让侧导航占屏幕的25%，主内容占75%。。。但那没用。。。所以我调整了主要内容以占据85%的屏幕，这很有效，但仅在PC上，在笔记本电脑上，这又很奇怪。。。我真的被困在这里了哈哈

Flexbox是您的朋友。您可能想了解更多信息，我无法在这里解释，但通过在父元素上设置display: flex;，您可以将宽度设置为25%和75%，以便将它们并排排列。
您在.divMain和.sidenav的多个位置也有一些代码，所以我清理了这些代码。您希望只在一个位置为每个选择器编写代码。
