CSS is crucial for styling and formatting web content.

Using custom fonts in CSS with @font-face allows you to apply unique typography to your web projects. You can use your own font files (e.g., TTF or OTF) or fonts from external sources like Google Fonts.
CSS variables, also known as CSS custom properties, are a powerful feature in CSS that allow you to define reusable values, such as colors, fonts, spacing, and more, and then use them throughout your stylesheets. They provide a convenient way to centralize and manage your design system's properties, making it easier to maintain and update your styles.
