What are some real-world examples of CSS variables?

CSS variables, or custom properties, are used in various projects for theming, responsive design, and maintaining consistency. For instance, a popular e-commerce site uses CSS variables to manage color themes for different seasons.

Can you give me another example?

Sure! A news website might use CSS variables to define font sizes and spacing, allowing for easy adjustments across different screen sizes and ensuring readability.

How do they help in maintaining consistency?

CSS variables allow developers to define a value once and reuse it throughout the stylesheet. This means if a color or size needs to change, it can be updated in one place, ensuring consistency across the entire site.

Are there any performance benefits?

Yes, using CSS variables can improve performance by reducing the amount of CSS code needed. Instead of repeating values, you can reference the variable, leading to smaller file sizes and faster loading times.
