Look & Feel

Open your Photobox module → Look & Feel tab.

Theme — Modern 2026 (default), Minimal, or Dark.
Accent Color — used for active filmstrip thumbs, control hover states, and accents (default #1819ed). Close-button hover uses this colour too.
Gallery Width — e.g. 100% or 900px.
Item Gap — spacing between thumbnails, e.g. 8px or 10.
Columns — 2 to 6 columns (responsive: fewer on tablets/phones).
Masonry Layout — Yes (default) for Pinterest-style flowing columns with natural image heights. No for a uniform CSS grid.

When masonry is on, thumbnails are resized by width only so heights stay natural.
Mixed portrait and landscape photos show the effect best.
Turn masonry off (Compact-style) when you want equal cells.
