I succeeded by tracking down the elements on the page which were given erroneously large min-width values. Now the page only scrolls up-down, the site title is well presented and the tagline too. Took some tinkering.
Still, for future referece: is there a CSS way to crop a page’s width from a core level (html or body?)? In a way that NOTHING can surpass the set value?
