How can I create a theme using CSS variables?

Creating a theme with CSS variables is a great way to manage styles. You can define your variables in a :root selector.

Can you give me an example of how to define these variables?

Sure! You can define them like this:

:root { --primary-color: #3498db; --secondary-color: #2ecc71; --font-size: 16px; }

Then, you can use these variables throughout your CSS.

How do I apply these variables to my styles?

You can use the variables in your CSS like this:

body { background-color: var(--primary-color); font-size: var(--font-size); }

This will apply the defined theme colors and font size.

Can I change the theme dynamically?

Yes! You can change the values of the CSS variables using JavaScript, allowing for dynamic theme switching.
