Once you've got your document written, you can start to tackle CSS. Since you've got a valid, well-formed document composed of semantically-meaningful elements, you'll find it much easier to style than people who focus upon the look of the document as they write it rather than its well-formed-ness. If you choose to hand it off to a dedicated frontend developer at this point, they'll be grateful that you've provided them with a solid canvas to build on.
I'm not sure where the rather sensationalist headline comes from, though; would you consider offering a nuanced argument as to why user data retention makes the company "evil" to back it up?
