CSS — Importing CSS
Importing CSS allows you to reuse styles from another CSS file. This is helpful for keeping your code organized and separating different styles. For example, you can have one file for general styles, another for a theme, and import them into your main stylesheet. The @import rule is used at the top of your CSS file. However, it is usually better to link CSS files directly in HTML for better performance.
@import url('theme.css');
