A theme is a style sheet (CSS) that changes how your Lizmap portal looks: colors, contrasts, spacing. The gallery is in the Marketplace, Customization section, Lizmap themes card.
The page offers a single action: Copy the CSS, which puts the style sheet in your clipboard. Nothing is applied to your instances: you put the file on your portal yourself, as explained in Using a theme. We never add or change any style sheet on your portal.
Each card shows a preview of the portal in the theme's colors, with its palette at the bottom. Then come its name, the Official mark for themes made by LizPack, its price (Free or Paid), its description, its rating, its variant (Light, Dark or Light & Dark), its number of copies and its tags.
