Design & theming
What it does
Pick a theme, set an accent colour, and adjust anything else element by element. The widget inherits your website font automatically, which is what stops it looking bolted on.
How it works
Seven presets on the main layouts — Custom, Light, Outline, Soft Tint, Deep Tint, Dark, Outline Dark — and three on stickers and badges. Around fourteen groups of settings cover background, header, rating, review card, popup, title, arrows, pagination, font, buttons and each badge type.
Backgrounds take a colour, a gradient, an image or a video. Corner radius, star size and colour, text size and every colour are adjustable individually.
The thing people get wrong
The font setting is the one people miss. Left on Default it picks up your site typography automatically — which is usually what you wanted and what makes the difference between a widget that fits and one that does not.
What it does not do
Anything the settings do not reach is a custom CSS field away, and there is a JavaScript field for the rest. Both are on every plan.
