/* static/css/gallery.css ────────────────────────────────────────────────────────────────────────────── Gallery slider + lightbox styles for hugo-mana-theme. Every colour/spacing value uses a variable already defined in theme.css so the gallery automatically matches the current dark/light theme. HOW TO INCLUDE: Add ONE line to your site's layouts/partials/head-extra.html (create that file at that path in your SITE ROOT if it doesn't exist, then check what the Mana theme calls for extra head content — look in themes/mana/layouts/partials/head.html for a reference to "head-extra" or similar). The simplest approach is to override head.html: Create: layouts/partials/head.html (copy from themes/mana/layouts/partials/head.html) Then add inside at the bottom: OR — just drop this into your existing site CSS if you have one. ────────────────────────────────────────────────────────────────────────────── */ /* ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SLIDER The .gallery-slider also carries .post-image-single from the Mana theme, so it gets the same border, shadow, border-radius, and margin-bottom automatically.
