Hi there! Is it at all possible to use CSS custom properties - similar to 'variables' in LESS/SASS - to define values to be reused throughout a project? For example, defining a value for 'main-colour', 'base-font-size' or 'main-font', which can then be changed easily throughout the project, simply by changing the value in one location?

If not, is there a different way to do this and achieve the same result? All guidance appreciated.
