CSS Custom Properties (or variables) are a powerful feature for creating maintainable and themeable stylesheets. This generator provides a simple interface to define a set of common theme variables, such as primary and secondary colors, fonts, and spacing units. It then generates a perfectly formatted `:root` block that you can place at the top of your CSS file. Using variables makes it incredibly easy to update your site's entire design system by changing just a few lines of code.

Frequently Asked Questions
What is `:root`?
In CSS, `:root` is a pseudo-class that represents the `<html>` element. It's the best place to declare global CSS variables because it has the highest specificity and makes the variables available everywhere in your document.
How do I use a CSS variable?
Once you've defined a variable (e.g., `--primary-color: #3498db;`), you can use it anywhere in your CSS with the `var()` function. For example: `button { background-color: var(--primary-color); }`.
