Design Tools
Browser-based tools for CSS and visual design: generate gradients with real-time preview, build layered box shadows, experiment with flexbox and grid layouts, create glassmorphism effects, pick colors from a wheel, and find complementary font pairings. Every tool outputs copy-paste CSS.
Generate CSS gradients, preview box shadows, explore glassmorphism effects, and build flexbox or grid layouts interactively. Each tool outputs copy-ready CSS you can paste directly into your project stylesheets. Whether you're crafting a color palette for a brand refresh, prototyping a card component with layered shadows, or tuning a responsive grid layout, these design utilities give you instant visual feedback.
Showing 18 design tools
Design tools that output code you can actually ship. Instead of screenshots, every generator here produces copy-paste CSS — gradients, shadows, palettes, and layouts — so the design and the implementation never drift apart.
Try CSS Gradient Generator first
Start with a gradient hero — it is the fastest win and teaches the color-stop mental model every other tool shares.
- 1
Pick two colors
Choose your stops and watch the gradient preview update in real time as you adjust.
- 2
Set the angle
Drag the angle control for linear gradients, or switch to radial or conic for other shapes.
- 3
Copy the CSS
Grab the background shorthand and paste it straight into your stylesheet.
What Each Tool Does
CSS Gradient Generator
Pick colors, set angles and stops, and see the gradient preview update in real time. Copy the CSS gradient() or background shorthand for use in your stylesheet.
Box Shadow Builder
Layer multiple shadows with separate color, blur, spread, and offset controls. The preview shows the shadow on a sample card so you can see how it looks.
Flexbox Playground
Set justify-content, align-items, flex-direction, and gap on a container. Watch how child elements respond to each property change.
CSS Grid Playground
Define rows, columns, and gaps visually. Place items by grid area or grid line. Great for learning how grid-template-columns and grid-template-rows work.
Color Palette Generator
Start with a base color and generate complementary, analogous, triadic, or split-complementary palettes. Each color shows HEX, RGB, and HSL values.
Font Pairer
Browse Google Fonts side by side. Preview heading and body text combinations at different sizes to find pairs that look good together.
Real Ways People Use These
Building a Landing Page
You need a gradient hero section and layered card shadows. Use the gradient generator and box shadow builder to get the exact values, then paste them into your CSS.
Learning CSS Layout
You're confused about how flexbox justify-content and align-items interact. The playground lets you toggle each property and see the effect immediately.
Picking a Color Scheme
You have a brand color and need three more for a palette. The color palette generator gives you complementary or analogous colors with their exact HEX values.
Finding Font Pairings
You want a sans-serif heading with a serif body font. The font pairer lets you browse Google Fonts and preview combinations before committing to a pair.
Pick the right tool for the job
Four common scenarios and the tool that handles each one.
| When you need to… | Use | Why |
|---|---|---|
| Build a layered card shadow | Box Shadow Builder | Stack multiple shadows with live preview instead of guessing offsets. |
| Center a layout that keeps breaking | Flexbox Playground | Toggle justify-content and align-items to see the interaction immediately. |
| Pick a palette from a brand color | Color Palette Generator | Generate complementary, analogous, or triadic sets with exact HEX values. |
| Choose heading and body fonts | Font Pairer | Preview Google Fonts side by side before committing to a pairing. |
Getting the most out of these tools
Build shadows in layers
A realistic shadow is two or three stacked offsets — a tight dark one and a wider, softer one.
Learn layout by toggling, not reading
Change one property at a time in the playground and the visual answer sticks far better than a tutorial.
Save palettes as CSS variables
Grab the HEX values into :root variables so the palette stays consistent across the whole site.
How it works
Generated CSS uses standard properties (background, box-shadow, display: flex/grid) that work in all modern browsers. No vendor prefixes are added by default, but you can toggle them for older browser support.
