   Backdrops page — luxury-backdrops-for-midlands-photobooths-kzn.html

   The tile style from durbanphotobooths.co.za/durban-photobooths-backdrops.html
   (7 Oct 2026): four across, each tile a button that opens the lightbox, the
   name set in the display face over a gradient at the foot of the artwork,
   and the zoom badge on hover.

   Kept in its own file, linked from that page only, rather than added to
   site.min.css: that file is cached as immutable with no ?v=, so a returning
   visitor would never see new rules in it. Everything here is scoped to
   .backdrops__grid--4, so the six-across strip on the homepage keeps its
   own look. Bump ?v= on the page's <link> after changing this file.
