I had a bookmark folder called "CSS Generators" with nine links in it.
One for flexbox layouts. One for grid. One for box shadows. One for glassmorphism. One for animations. One for clip-path shapes. One for loaders. One for text shadows. One for border radius.
Nine different sites, nine different interfaces, nine different levels of ad intensity. I couldn't even remember which bookmark was which anymore — I'd click three wrong ones before finding the box shadow generator.
So I put them all in one place.
The Generators
Anytools.io/design — all nine, same interface, same workflow:
1. CSS Flexbox Generator
Visual builder for flexbox layouts. Set flex-direction, justify-content, align-items, flex-wrap, and gap using controls instead of typing CSS from memory. Add child items, adjust their individual flex-grow, flex-shrink, flex-basis, order, and align-self. Live preview updates as you click. Copy the generated CSS when you're happy.
When I use it: Prototyping navigation bars, card layouts, centering things (yes, still).
2. CSS Grid Generator
Define rows, columns, gaps, and named areas visually. Drag to create grid areas, set explicit track sizes (fr, px, %, auto, minmax), configure justify-items and align-items. The preview shows the actual grid lines so you can see exactly what you're building.
When I use it: Dashboard layouts, magazine-style content grids, anything with more than two dimensions of layout control.
3. Box Shadow Generator
Multi-layer shadow editor with real-time preview. Add multiple shadows, adjust offset-x, offset-y, blur, spread, and color for each layer independently. Supports inset shadows. The preview shows shadows against your chosen background color so you can see how they'll actually look.
When I use it: Card elevation effects, subtle depth on buttons, neumorphism experiments.
4. CSS Animation Generator
Build keyframe animations without writing @keyframes by hand. Set animation properties (duration, timing-function, delay, iteration-count, direction, fill-mode), define keyframe steps visually, and preview the animation in real time. Generates both the @keyframes block and the animation shorthand.
When I use it: Loading states, hover transitions, entrance animations, attention-grabbing UI elements.
5. Glassmorphism Generator
The frosted-glass effect that's everywhere right now. Adjust backdrop-filter: blur(), background opacity, border, and border-radius. Preview against a background image so you can see the actual frosted glass effect, not just a semi-transparent box.
When I use it: Modal overlays, floating cards, hero section overlays, navigation bars.
6. CSS Loader Generator
Animated loading spinners and progress indicators, pure CSS. Multiple loader styles — spinners, dots, bars, rings, pulses. Customize colors, size, and speed. Copy a single block of CSS + HTML.
When I use it: Loading states while data fetches, skeleton screens, form submission indicators.
7. Clip-Path Generator
Custom shapes with a visual polygon editor. Click to add points, drag to adjust, and see the shape update in real time. Includes presets for common shapes (triangle, pentagon, star, arrow) as a starting point. Generates the clip-path: polygon() value.
When I use it: Hero image masks, decorative section dividers, creative image framing.
8. Text Shadow Generator
Layered text shadows with preview. Add multiple shadow layers, adjust offset, blur, and color for each. Preview on different background colors and font sizes to see how the shadow reads at various scales.
When I use it: Headings over images, retro text effects, subtle depth on light backgrounds.
9. Border Radius Generator
Asymmetric rounded corners — because border-radius: 10px isn't always what you want. Control all eight values independently (each corner has a horizontal and vertical radius) using sliders. The preview shows the exact shape you're creating.
When I use it: Organic shapes, blob-like containers, creative button designs.
Also on the Design Page
The CSS generators sit alongside a bunch of other design tools:
- Color Palette Generator — generate harmonious palettes from a base color
- Gradient Generator — linear, radial, and conic gradients with unlimited color stops
- Contrast Checker — WCAG AA/AAA compliance for text/background combinations
- Tints & Shades Generator — produce 10 tints and 10 shades of any color
- Type Scale Generator — modular type scales for consistent typography
- Font Pair Suggestions — Google Fonts pairings that work together
- SVG Optimizer — compress SVGs by removing unnecessary metadata
- Favicon Generator — create favicons from text, emoji, or uploaded images
Why One Site Instead of Nine
Three reasons:
1. Consistent interface. Every generator works the same way: adjust controls on the left, see preview on the right, copy code at the bottom. No relearning a new UI every time I switch tools.
2. No context switching. When I'm building a card component, I might need box shadow, border radius, AND glassmorphism. Having them in the same place means I stay in flow instead of tab-hopping.
3. No friction. No sign-ups, no "pro tier" for the good features, no cookie consent banners covering half the screen. The generators just work.
Everything runs client-side in the browser. No data sent anywhere. Anytools.io is free and has 89 tools total across dev, design, calculators, and health/fitness.
Which CSS property do you find yourself reaching for a generator most often? I'm always looking to add more tools — the clip-path generator was actually a user request.
