How can I use custom CSS variables in my Angular project?

You can define custom CSS variables in your stylesheets and use them in your Angular components. For example, in your styles.css file, you can add:

:root { --main-bg-color: #f0f0f0; --main-text-color: #333; }

Then, in your component styles, you can use these variables like this:

background-color: var(--main-bg-color); color: var(--main-text-color);

Can I change these variables dynamically?

Yes, you can change CSS variables dynamically using JavaScript. In your Angular component, you can access the root element and set the variable like this:

document.documentElement.style.setProperty('--main-bg-color', '#ff0000');

Are there any browser compatibility issues I should be aware of?

Most modern browsers support CSS variables, but if you need to support older browsers like Internet Explorer, you might want to consider using a fallback.

What are some best practices for using CSS variables?

Some best practices include keeping your variable names consistent, using them for theme colors, and avoiding too many nested variables to maintain readability.
