What are some examples of CSS variables?

CSS variables, also known as custom properties, allow you to store values that can be reused throughout your stylesheet. For example:

:root {
  --main-color: #3498db;
  --padding: 16px;
}

.button {
  background-color: var(--main-color);
  padding: var(--padding);
}

Can you explain how to use them in a project?

Certainly! To use CSS variables, define them within a selector (often :root for global access) and then use the var() function to apply them. This makes it easy to maintain and update styles.

What are the benefits of using CSS variables?

CSS variables provide several benefits, including easier maintenance, dynamic theming, and reduced redundancy in your stylesheets. They allow for quick updates across your entire site.

Are there any browser compatibility issues?

CSS variables are widely supported in modern browsers, but older versions of Internet Explorer do not support them. It's always good to check compatibility if you're targeting older browsers.
