What are CSS variables (custom properties) and how to use them

CSS variables, also known as custom properties, allow you to store values in a variable-like fashion. This way, you can reuse the same value throughout your stylesheets, making your CSS more maintainable and easier to update.

To declare a CSS variable, you use the syntax --variable-name within a CSS selector. You can then access this variable using the var() function.
