Template:UI/posts library/styles.css

/* TemplateStyles for {{UI/posts_library}} — curated Posts directory.
   Header (heading + lead) and a responsive card grid of post cards.
   Each card has a 4:3 image area on top (Has card image, or a flat
   gradient fallback), then a body with title, a date · author meta
   line, and a line-clamped description teaser.

   Sanitizer constraints (MW 1.44.5 / css-sanitizer 5.5.0): same as the
   other library stylesheets — var() in `background`, `color`, and the
   `border` shorthand only; geometry stays literal. `display:
   -webkit-box` is rejected, so the description teaser uses the
   max-height + overflow:hidden approximation rather than
   -webkit-line-clamp. `aspect-ratio` is rejected too, so the image
   area uses the padding-bottom hack. */

/* ---------- Card grid ----------

   Explicit column counts at each breakpoint rather than
   auto-fit/minmax: auto-fit collapses to a single 1fr track when only
   one post exists, which stretches a lone card to full width and blows
   up the image. Explicit columns keep cards sized uniformly regardless
   of result count. gap stays literal per the geometry-literal
   constraint. */
