在这个页面的左上角，我有一个“亮/暗模式”切换。当“亮模式”被点击，它很好地淡入到暗模式没有问题。但是一旦它在暗模式，你点击“亮模式”，它不淡入很好，我似乎不能让它工作。我需要添加什么到我的代码，让它很好地淡入到亮模式？

你需要把
tranition效果应用到受黑暗主题影响的元素上，而不是dark-mode类本身，不过你对#dark-mode-button做得很好。您的代码的解决方案：在
html{}和.tabs a {}上添加一个过渡（transition: all 0.5s ease-in-out），您可以移除dark-mode类上的transition效果。Fiddle：https://jsfiddle.net/40y5axcd/注意：你在整个html中使用了白色的文本颜色，所以你的
main内容文本在白色背景下是不可见的，我没有改变，因为它不是你问题的一部分。接下来，你最好使用一个带有
transition效果的实用类，并将其应用于所有受暗模式影响的元素，特别是如果你继续向页面添加元素，并希望更改过渡持续时间。你宁愿只更改一个类，然后必须遍历每个元素并更改持续时间。
