How to add an external css style prompt in the html document, because I am using the template syntax for the framework

Hello,

This forum is dedicated to PhpStorm and questions about configuring and using that IDE.

If you are facing issues with creating a certain code structure, I would suggest to clarify the questions at some user group forums or communities like StackOverflow.

I now encountered can not automatically prompt CSS code

can you clarify what you mean by prompting CSS code? Is it about CSS selectors completion in PhpStorm, or? What does your HTML look like?
