I'm tempted to reply that a brutalist website would be one that keeps decoration to a minimum, but.....that wouldn't fit, because (for example) the Geisel Library has plenty of decoration, it's just in concrete and glass.
Maybe a brutalist HTML page would have the tags embedded, kind of like the WordPerfect codes.
