Let’s say I want something that is in a large font, say 48px, for desktop. Don’t want to use a heading because it’s unimportant text (SEO wise). But I want it to be responsive, so 28x on mobile, for example. I can copy CSS and manipulate it to how I need it, but not good at creating it out of thin air.
I’ve seen prior posts about @media but how do I create a special class or selector so I can use this throughout the site?
