如何停止 Laravel 错误（预期规则或选择器）

Question

Error on public/app/app.css

While i was just working on other stuff i found the error on this page.

Answer 1

I think you are missing selector, you just write property and value of CSS,

h1 {
  font-family: Arial, Helvetica, sans-serif;
  text-size-adjust: 80%;
}

h1 is selector, you can write here your class name or id name according to your project or program need.

Answer 2

comment this line has solved the problem (vscode says it is a problem, not me) for me :

/* @charset "UTF-8"; */

NB: I think your css file is supposed to be in public/css/, not in public/app. Ideally and to respect the semantics, of course.
