Change Text Style

Apply a style patch to a text overlay (font, size, color, etc.). Can also change text content simultaneously.

How It Works

styles_patch is merged into TextOverlay.styles. Below is every supported property. The user will describe what they want visually — interpret their intent and set the right combination of properties. They will never say property names. TYPOGRAPHY: fontSize: string — e.g. "48px", "3.2rem" (range: 8-120px) fontFamily: string — available fonts and their character: font-sans (Inter, clean modern), font-serif (Merriweather, classic editorial), font-mono (Roboto Mono, code/tech), font-retro (VT323, pixel/VHS/8-bit), font-league-spartan (bold geometric display), font-bungee-inline (funky display/music), font-poppins (friendly rounded modern), font-playfair-display (luxury elegant serif), font-oswald (condensed sports/news), font-bebas-neue (cinematic tall condensed), font-pacifico (handwriting cursive script) fontWeight: string — "200" (thin) thru "900" (black). Use weight to convey feeling: 200-300 = delicate/elegant, 400-500 = normal, 700 = bold, 800-900 = heavy/impactful fontStyle: string — "normal" or "italic" textDecoration: string — "none" or "underline" textAlign: string — "left", "center", or "right" textTransform: string — "uppercase", "lowercase", or "" (none) lineHeight: string — e.g. "1.1" tight, "1.4" relaxed (range: 0.8-2.0) letterSpacing: string — e.g. "-0.03em" tight, "0.12em" wide, "0.25em" very spaced out COLOR & BACKGROUND: color: string — text color as hex e.g. "#FFFFFF", "#00FF41" backgroundColor: string — solid bg e.g. "rgba(79,70,229,0.85)", "" for none background: string — CSS gradient e.g. "linear-gradient(135deg, #6366F1 0%, #EC4899 50%, #F59E0B 100%)" GRADIENT TEXT (3 properties together — fills the text itself with a gradient): background: "linear-gradient(...)"
