可以嵌套 CSS 文件吗？

Can CSS Files Be Nested?

CSS files provide a means of styling web pages. Is it possible to include one CSS file within another?

Yes, you can include one CSS file in another using the @import rule.

The syntax for @import is as follows:

@import url("base.css");

Important notes:

• The @import rule must appear before all other CSS rules (except @charset).
• Importing multiple CSS files can result in additional server requests. To avoid this, consider concatenating all CSS into a single file. For instance, you can copy the contents of base.css and special.css into base-special.css and reference only base-special.css.
