The CSS Generator Collection is a three-in-one tool covering three of the most commonly needed CSS property generators: Border Radius, Transform, and Filter. The Border Radius tab provides four sliders (top-left, top-right, bottom-left, bottom-right) each controlling 0–100px corner radii, with a live rounded rectangle preview. The Transform tab offers six sliders for rotate (-360 to 360 degrees), scale (0 to 3), skewX (-90 to 90 degrees), skewY (-90 to 90 degrees), translateX (-100 to 100px), and translateY (-100 to 100px), with a live green rectangle showing the combined transformation. The Filter tab provides five sliders for blur (0–20px), brightness (0–200%), contrast (0–200%), grayscale (0–100%), and sepia (0–100%), previewed on a text element.
Front-end developers and UI designers use this collection to quickly experiment with multiple CSS properties without switching between different tools. The three-tab layout keeps the workflow focused — you pick the property category you need, adjust the sliders, and copy the generated single-line CSS declaration. For design work, being able to visually see how transform combinations look together (rather than calculating matrix math mentally) and how filter chains affect visual appearance saves significant time during prototyping.
Each tab generates a single, complete CSS property declaration. The Border Radius tab outputs `border-radius: TLpx TRpx BRpx BLpx;`. The Transform tab composes all six transform functions into a single `transform: rotate() scale() skew() translate();` declaration. The Filter tab chains all non-default filter functions into a single `filter: blur() brightness() contrast() grayscale() sepia();` declaration. A shared copy button copies the currently active tab's CSS to the clipboard.

Frequently Asked Questions
What CSS transform functions does this tool support?
The Transform tab supports rotate (degrees), scale (multiplier), skewX (degrees), skewY (degrees), translateX (pixels), and translateY (pixels). All six are combined into a single CSS transform property value. For example: `transform: rotate(45deg) scale(1.5) skew(10deg, 0deg) translate(20px, 0px);`. The browser applies the functions from left to right, so the order matters for the final visual result.
What is the difference between rotate and skew in CSS transform?
rotate() turns the entire element around its transform-origin point (center by default), preserving its shape. skew() distorts the element by tilting it along the X axis, Y axis, or both, creating a parallelogram-like effect. Rotate affects the orientation of the shape without distortion; skew deforms the shape itself. Both are specified in degrees.
How does CSS filter blur work?
The blur() CSS filter applies a Gaussian blur to the element and everything inside it. The value is in pixels — larger values create a stronger blur effect. `filter: blur(0px)` means no blur; `filter: blur(10px)` creates a visibly blurred appearance. Unlike backdrop-filter, which blurs what is behind an element, filter: blur() blurs the element and its own content.
What does the brightness filter do?
The brightness() filter adjusts the overall luminosity of an element. A value of 100% (1) is the original brightness. Values below 100% darken the element (0% is fully black). Values above 100% make the element brighter — 200% doubles the brightness. It applies uniformly to all pixels, making it useful for hover state effects or darkening image overlays.
Can I combine multiple CSS filters?
Yes. CSS filter accepts multiple functions separated by spaces in a single filter property. The generator combines all five filter functions (blur, brightness, contrast, grayscale, sepia) into one declaration. For example: `filter: blur(2px) brightness(120%) contrast(90%) grayscale(50%) sepia(0%)`. Filters are applied in order from left to right, so changing the order can produce different results.
What does the CSS transform scale() function do?
scale() resizes the element visually without affecting its layout footprint. A value of 1 is the original size. Values less than 1 shrink the element (0.5 = half size). Values greater than 1 enlarge it (2 = double size). The scaling happens around the transform-origin (center by default), so the element appears to grow or shrink from its center point. Unlike width/height changes, scale() does not reflow surrounding elements.
What is the difference between grayscale and sepia filters?
grayscale() converts the element to a black-and-white image. A value of 0% means full color; 100% means completely gray with no color information. sepia() applies a warm brownish-orange tone resembling old photographs. A value of 0% is the original color; 100% is full sepia. You can combine both — for instance, `grayscale(50%) sepia(30%)` creates a muted warm-toned effect.
How do transform functions combine in the generated output?
The tool generates a single transform property with all six functions written in order: rotate, scale, skew (as skew(skewX, skewY)), and translate (as translate(X, Y)). CSS transform functions apply sequentially — the coordinate system is transformed by each function before the next one is applied. This means a rotate followed by a translateX moves the element along the rotated axis, not the original horizontal axis.
