Yes, fotolog.com doesn't exist anymore but I would gladly elaborate. (full explanation here: http://minid.net/2019/04/07/the-css-utilitarian-methodology/) resume: why go with an OO architecture, when you can use inmutable classes and never again repeat the same properties in your CSS files. In the end, you end up developing faster and you can mantain code easily without having to build the entire UI arquitecture in the CSS. CSS was created to separate style from the content, but also, because back then, HTML wasn't built like we do today with frameworks. Now that we use reactive HTML we can just print inline CSS, but that is a problem, so the functional CSS comes better.
