A CSSmatic alternative for visual CSS generators
People searching this way want to design a CSS surface visually and copy out the rule, rather than write the property by hand.
Convertto has a set of visual CSS generators that cover the same surface work: gradients, border radius, box shadow and repeating patterns, plus buttons, glassmorphism, neumorphism and loaders. Each one previews live as you drag a control and outputs CSS you can paste. They run entirely in the page, with nothing to install and no account.
- Approach
- Drag a control, see the result, copy the rule
- Output
- Plain CSS, ready to paste
- Where it runs
- In the page. Nothing is sent anywhere
- Cost
- Free, no sign-up

| Loading spinners | CSS Loader Generator | Builds a spinner, dots, bars or a pulse from pure CSS, keyframes included |
Why a visual generator is worth the click
Most CSS is quicker to type than to configure. Four properties are the exception, because their values are not readable as numbers: background-image with a gradient, box-shadow, border-radius with four differing corners, and clip-path. In each case the gap between the value and the result is wide enough that a preview is genuinely faster than a reload, and that is what these generators are for.
Shadows read better in layers
A single large blurred shadow is the usual first attempt and it always looks slightly wrong, because real elevation produces both a tight contact shadow and a wide ambient one. Two stacked shadows, a small tight one and a larger soft one, read as height in a way one never does. The box shadow generator outputs the layered version alongside the single-shadow rule so you can compare them directly.
/* one shadow: flat */
box-shadow: 0 8px 24px rgba(0, 0, 0, 0.18);
/* two shadows: contact plus ambient */
box-shadow:
0 1px 2px rgba(0, 0, 0, 0.10),
0 8px 24px rgba(0, 0, 0, 0.12);Gradients and the grey dead zone
A two-stop gradient between distant hues passes through a desaturated middle, because interpolating in sRGB cuts across the centre of the colour space. Adding an intermediate stop at a saturated colour pulls the ramp back out to the edge and removes the grey band. The gradient generator lets you add stops and see the effect immediately.
The rest of the set
Beyond the surface generators there are tools for flexbox, grid, clip paths, filters, transforms, easing curves and media queries. The CSS generators hub lists all of them.
