Is it possible to change css through the panel?

In my panel I want to have the option to change css properties of elements. For example change a background-color or a font-family of text on the website.
Is it possible to e.g. paste a google font url in a panel field to change the font family of p, h1, h2 … ?
By now I did not managed to connect dynamic fields with css.

Thanks in advance!

Yes, this is possible. However, obviously you cannot use these dynamic styles in a .css stylesheet but would have to include these styles either in a style element in your header snippet/templates, or you need some way of generating your stylesheet(s) dynamically.

Alright, thanks!
