CSS visual generator workspace

Three focused tools with sticky navigation and live browser rendering.

Gradient type and geometry

Linear, radial or conic

Color stops

2–8 stops · opacity supported

Gradient presets

Editable starting points

Three visual CSS generators for everyday front-end work

This workspace keeps the most frequently adjusted decorative CSS properties together. Build a gradient background, tune realistic or expressive shadow layers, and shape corners without repeatedly editing declarations by hand.

CSS gradient generator

Create linear, radial and conic backgrounds with repeating modes, multiple positions and transparent color stops.

Box-shadow generator

Combine up to eight outer or inset layers and evaluate the result against adjustable element and stage colors.

Border-radius generator

Control every corner, switch units, link values and use separate horizontal and vertical radii for organic shapes.

How to generate CSS visually

The visible workflow and structured instructions use the same five steps.

  1. Choose a CSS generatorOpen Gradient, Box Shadow or Border Radius from the sticky workspace tabs.
  2. Adjust the visual controlsChange colors, positions, dimensions, layers, corner values and other settings while watching the live preview.
  3. Review the generated CSSInspect the standards-based declaration shown beside the preview and refine the controls as needed.
  4. Copy or download the codeCopy the current declaration or download an individual CSS file with a correctioncopy.com_ filename.
  5. Export all three stylesUse Copy All CSS or Download All CSS to collect the current gradient, shadow and radius examples in one stylesheet.

Gradient backgrounds with controllable color transitions

CSS gradients are generated images made from progressive transitions between two or more colors. Linear gradients follow an axis, radial gradients expand from a center, and conic gradients rotate around a center point.

Precise stop positions

Percentage positions make smooth blends, hard boundaries, banded backgrounds and repeating stripes possible without image files.

Transparent stops

Independent stop opacity can create fades, overlays and spotlight effects while preserving the selected base color.

Editable presets

Presets load practical starting configurations, but every type, angle, center and stop remains editable.

Layered CSS box shadows for depth, elevation and glow

A box shadow can use offsets, blur, spread, color and an inset keyword. Multiple comma-separated shadows are painted in order, allowing soft elevation, crisp outlines, ambient depth and neon-style glow.

Up to eight layers

Reorder enabled layers to control overlap and preserve the exact sequence in the generated declaration.

Outer and inset effects

Mix exterior and interior shadows for raised controls, pressed surfaces, cards and framed components.

Context-aware preview

Change element dimensions, fill, corners and stage color without polluting the copied box-shadow property.

Independent and elliptical border-radius CSS

The border-radius shorthand can define all four corners and can use a slash to separate horizontal from vertical radii. That makes simple rounded cards, pills, circles and asymmetrical organic shapes possible.

Optimized shorthand

Repeated values are compressed into the shortest clear one-, two-, three- or four-value declaration.

Elliptical corners

Separate horizontal and vertical controls produce the standards-based slash form used for stretched corner curves.

Pixels, percentages and rem

Choose fixed dimensions, responsive percentage geometry or root-relative radii according to the component design.

Private browser-session CSS generation

No page-specific upload or storage

Control values and generated declarations remain in the current page. No page-specific server endpoint receives the CSS.

No external processing dependency

The previews use native browser CSS rendering. No tool-specific library, account or API key is required.

Clean reset and downloads

Reset restores the editor defaults. Generated downloads use temporary browser references that are released after use.

Review in the target layout

Inherited styles, surrounding backgrounds and component dimensions can change the final appearance, so test copied CSS in context.

Browser rendering and implementation considerations

Color appearance varies

Display calibration, color profiles and panel characteristics can influence perceived gradients and shadows.

Large shadows affect paint cost

Many large blurred layers can increase rendering work, especially during animation or on lower-powered mobile devices.

Percent radii depend on size

Percentage corner geometry changes with element dimensions, so responsive shapes should be checked at multiple sizes.

Conic gradients are visual

Do not rely on a conic gradient alone to convey essential data because CSS-generated imagery has no built-in text alternative.

Old browser fallbacks

The generated syntax targets current browsers. Legacy projects may need a solid-color fallback or a simplified declaration.

Presets are starting points

Review contrast, motion, focus visibility and surrounding context before shipping decorative styles in a real interface.

CSS generator frequently asked questions

Answers about gradient syntax, shadow layers, corner radii, exports, mobile use, privacy and production implementation.

What is included in this CSS generator?

It combines a CSS gradient generator, a multiple-layer box-shadow generator and a border-radius generator in one responsive developer workspace.

Does the tool generate real CSS?

Yes. Every preview is driven by the same CSS declaration shown in the output field, so the copied code reflects the current controls.

Can I create linear, radial and conic gradients?

Yes. The gradient generator supports linear, radial and conic gradients, including repeating variants, multiple color stops, stop opacity and adjustable positions.

How many gradient color stops can I add?

You can use between two and eight stops. Each stop has a color, opacity and percentage position.

Can gradient stops share the same position?

Yes. Equal or closely spaced positions can create hard transitions and striped effects, especially with repeating gradients.

What does a repeating gradient do?

A repeating gradient repeats the defined color-stop pattern instead of stretching it once across the entire element.

Can I control the center of radial and conic gradients?

Yes. Horizontal and vertical center controls position the gradient origin as percentages of the preview area.

Can I make transparent gradient stops?

Yes. Lower a stop opacity below 100 percent. The generated CSS uses an rgba color when transparency is needed.

Can the box-shadow generator create multiple shadows?

Yes. You can add, remove, enable, disable and reorder up to eight shadow layers.

Which box-shadow values can I control?

Each layer includes horizontal offset, vertical offset, blur radius, spread radius, color, opacity and an optional inset setting.

Which box-shadow layer appears on top?

When multiple shadows overlap, the first shadow listed in the CSS declaration is painted above the later shadows.

Can I create an inset shadow?

Yes. Enable Inset on any layer to render the shadow inside the preview element.

Can I preview shadows on different backgrounds?

Yes. The preview controls include stage color, element color, width, height and corner radius so the shadow can be evaluated in context.

Can I make a neon or glow effect?

Yes. Use one or more zero-offset shadow layers with increasing blur values and bright colors, or start with the included Neon preset.

Can box-shadow spread be negative?

Yes. A negative spread contracts the shadow shape before blur is applied, while a positive spread expands it.

Does border-radius support four independent corners?

Yes. Top-left, top-right, bottom-right and bottom-left values can be edited independently or linked together.

Can I create elliptical border radii?

Yes. Enable Elliptical corners to control horizontal and vertical radii separately and generate the slash syntax.

Which border-radius units are available?

The generator supports pixels, percentages and rem units. Percentage values are useful for circles, pills and organic shapes.

How do I create a perfect circle?

Choose the Circle preset, which uses equal preview width and height with a 50 percent border radius.

How do I create a pill-shaped element?

Choose the Pill preset or use a very large pixel radius on a wide, short element.

What is the border-radius slash syntax?

Values before the slash define horizontal corner radii, while values after the slash define vertical corner radii. This creates elliptical corners.

Can I copy only one declaration?

Yes. Each generator has its own Copy CSS and Download CSS controls.

Can I export all three tools together?

Yes. Copy All CSS and Download All CSS generate one stylesheet containing example classes for the current gradient, box shadow and border radius.

Do downloaded filenames use the CorrectionCopy prefix?

Yes. Every downloaded stylesheet begins with correctioncopy.com_ and uses a descriptive CSS filename.

Does this tool upload or store my CSS?

No page-specific endpoint receives the settings or generated declarations. The editor state exists only in the current browser page.

Do I need an account, installation or browser permission?

No. The tool requires no page-specific account, installation, file upload, camera, microphone or device permission.

Does it work on mobile devices?

Yes. Controls stack on narrow screens, touch targets remain usable and the preview moves below the controls when a side-by-side layout would be too narrow.

Which browsers support the generated CSS?

Current stable Chrome, Edge, Firefox and Safari support the core gradient, box-shadow and border-radius syntax generated here. Very old browsers may require different fallbacks.

Why can a gradient look slightly different between displays?

Color profiles, display calibration, panel technology and browser rendering can affect perceived color and banding even when the CSS declaration is identical.

Does the preview guarantee identical production rendering?

The preview is a direct browser rendering of the declaration, but surrounding layout, inherited styles, color management and target-browser versions can affect the final page.

How do I start over?

Use Reset This Tool inside the active generator or Reset All in the workspace header to restore the production defaults.
