vs代码中的CSS问题

Question

I'm new in VS Code and I'm trying to figure out what went wrong here because css won't work for me. The link is good because it opens with click + ctrl. Both files are in the same folder. So why isn't it working?

Answer 1

Seems like you didn't save index.html . See the round dot? It means it's not saved.

Your code seems fine. Also, it's always better to use a browser than using built in preview.

Answer 2

使用浏览器并保存您的文件更改以查看您的项目。

Answer 3

Save file and try opening it with a browser. I always prefer browser to test a file. Sometimes 2 browsers if it has a problem. I suggest you to use sublime text 3 or notepad ++ with vs code because it can save you from a lot of headaches. :)
