CSS Card Generator

Background, border, radius and shadow, combined into one card style -- solid, gradient border, glass, outline or elevated, with a real hoverable preview and an optional filled-in content layout, not just an empty box.

What this tool does

Builds a complete card style — background, border, radius, shadow — with a real, hoverable preview that can show actual filled-in content (an image block, title, description, and button), so the card can be judged as it will actually be used rather than as an empty rounded box.

Five card styles

Solid, glass (translucent with backdrop blur), outline, and elevated (soft-UI with an automatic light/dark shadow pair) cover the common cases. Gradient border is a real double-background trick — a solid inner padding-box background layered under a gradient border-box background — the correct way to get a gradient border with a solid card interior, rather than the transparent-background trick that only works with a page background showing through.

Background, border and shadow controls

A solid or gradient background, border colour/width/opacity (relevant styles only), corner radius, and shadow distance/ opacity/colour are all independently adjustable, plus the card's own width, height, and padding.

Real hover and filled content

Five hover effects — lift, scale, glow, border highlight, or none — apply as a genuine CSS :hover rule on the preview, testable by hovering it directly. Content can be toggled from empty to a filled layout with an image placeholder, title, description text, and a button, so the finished look is obvious at a glance.

Presets and randomizing

Five presets — Minimal, Frosted Glass, Neon Border, Elevated, and Flat Outline — cover common looks, plus a randomize button for quick exploration.

Getting the CSS out

Export as plain CSS (with a separate :hover rule), a Tailwind class string (including hover: variants), SCSS, or a React inline style object, copyable with one click.

Frequently asked questions

Is my data uploaded anywhere?
No. The card is built and rendered entirely in the browser -- nothing is sent to a server.
How does the gradient border style actually work in CSS?
It layers two backgrounds: a solid colour clipped to the padding-box (the card's interior) under a gradient clipped to the border-box, combined with a transparent border -- the correct technique for a gradient border with an opaque card interior, unlike the transparent-background trick that only shows a gradient if the page behind it is also that colour.
Can I preview the card with real content instead of an empty box?
Yes -- the content option fills the preview with an image placeholder, a title, description text, and a button, so the finished card is obvious at a glance.
Can I actually try the hover effect, not just read about it?
Yes -- the preview is a real element with a genuine CSS :hover rule, so hovering it directly shows the lift, scale, glow, or border-highlight effect.
What is the elevated card style?
A soft-UI look derived from a single background colour -- a light and a dark shadow are computed automatically and combined with the regular drop shadow for a subtly raised appearance.
What export formats are available?
Plain CSS with a separate :hover rule, a Tailwind class string including hover: variants, SCSS, or a React inline style object -- selectable from a dropdown next to the code output.
