Theming
Almost everything is set in the console — icons (built-in, a 200k+ icon library, or your own SVGs), colors, corner, fall speed, and layout — with a live preview. For finer control, the bar reads --tapback-* CSS custom properties from the page, so you can drive them from your own stylesheet:
:root {
--tapback-accent: #ff4d6d;
--tapback-size: 40px; /* icon size */
--tapback-gap: 20px; /* space between reactions */
--tapback-bar-bottom: 2rem;
}
The console's Appearance panel writes these for you; anything it doesn't cover you can set by hand.
