Css problem

Question

Why my css don't connect my html at this app??

Answer 1

Which app? Share your code

Answer 2

The Sololearn compiler has all 3 Web languages (HTML, CSS, JavaScript) linked automatically. You don't need to link it.
Or, are you trying to link to another css file elsewhere? Is it publicly accessible? As Mehdi said, it would help if we could see the code. Here's a guide:
