Seems to me that a truly minimalist website would have to be set in Times Roman (is that not still the default typeface). And that a truly brutalist website should have a gray background.
Both utterly pedantic quibbles that are completely intended to be ignored.
Good job.
Good bait!!!
Truly minimalist: Accept the defaults. Whatever they are. Count your bytes.
Aesthetic minimalism: A non-serif font. We may have strong opinions here on which. I shall name none to avoid firey flames ;-)
By pointing out Times New Roman by name you do not imply minimalism. Rather a passive aggressive swipe at good old Times New Roman which I find too practical and beautiful to be lumped into nu-brutalism nor aesthetical minimalism. To show good faith I will let the missing "New" slide. Gentlemen shall be given room to misspeak. Happens to the best of us.
Mupen, Boa Constructor and Molend are good examples from an otherwise meh list at https://www.fontspace.com/category/brutalist.
A drab grey could be brutalist indeed. Maybe we can be friends after all! But truly! I beg your pardon! One true scotsman and all that jazz.
Pendatry to be ignored? No, no! That is not how pendantry works! You need to watch more Tim Traveller.
But good bait, fun times!
Times New Roman you mean, surely
Can't improperly reference that legendary script.
