CSS Button Generator
The ultimate CSS button builder. Features 50+ professional presets (Neumorphism, Glassmorphism, 3D), WCAG accessibility audits, and instant export to CSS, SCSS, or Tailwind JIT.
About
In web development, the "Call to Action" (CTA) button is the single most critical element for conversion rates. However, coding modern, interactive, and accessible buttons from scratch is time-consuming and prone to inconsistencies. This tool solves that friction by combining a massive library of high-performance presets with a granular fine-tuning engine. It is designed for developers who need production-ready code immediately, without toggling between Figma and VS Code.
Accuracy in UI design extends beyond aesthetics; it involves strict adherence to accessibility standards. A button with poor contrast ratio (R < 4.5) renders a site unusable for visually impaired visitors and can negatively impact SEO scores. This application calculates relative luminance in real-time, ensuring every generated style meets WCAG 2.1 AA or AAA standards. It handles complex CSS logic, including multi-layer box-shadows for Neumorphism, backdrop-filters for Glassmorphism, and gradient interpolations.
Formulas
To ensure accessibility, the tool calculates the Contrast Ratio CR using the relative luminance of the text Lt and the background Lbg. The formula follows W3C standards:
Where L1 is the greater luminance value between Lt and Lbg. The relative luminance L is derived from the sRGB color space components, normalized as follows:
This non-linear transformation accounts for the gamma correction of human vision.
