Skills you'll earn: CSS gradients (linear/radial/conic), color interpolation, code generation, preset management

Start with two colors. End with a full CSS gradient design tool.

(Assumes basic HTML/CSS/JS knowledge. Includes learning CSS gradient syntax deeply and drag interactions.)

Step 1: A linear gradient between two colors (~1 hour)

You need a gradient background for a section. You want to preview it instantly.

• One HTML page with a full-viewport <div>
• Two color pickers: start color and end color
• Apply a CSS linear-gradient to the div, updating on every change
• Show the CSS code below the preview

You now have: A two-color gradient previewer.

Step 2: Direction control (~1-2 hours)

Your gradient goes left-to-right. You want it diagonal.

• Add a direction control: angle slider (0-360 degrees) or preset buttons (to top, to right, to bottom-right, etc.)
• Update the linear-gradient direction in real time
• Show a small compass or arrow indicating the current direction
• Display the updated CSS

You now have: Directional gradients.

Step 3: Multiple color stops (~3-4 hours)

Two colors are limiting. You want complex gradients with three, four, or more stops.

• Show color stops on a gradient bar (like a ruler)
• Click the bar to add a new stop
• Drag stops to reposition them
• Click a stop to change its color
• Right-click to remove a stop

You now have: Multi-stop gradients.

Step 4: Radial and conic gradients (~2-3 hours)

Linear isn't the only option.

• Add gradient type selector: linear, radial, conic
• For radial: let users set the center position (click on the preview to reposition)
• For conic: let users set the starting angle
• Update the CSS output for each type

You now have: All CSS gradient types.

Step 5: Presets and randomization (~2-3 hours)

Starting from scratch every time is tedious.

• Build a gallery of preset gradients (curated, good-looking combinations)
• Add a "Random" button that generates a pleasant gradient
• Use color harmony rules to avoid ugly combinations
• Let users save custom gradients to localStorage

You now have: Presets and quick generation.

Step 6: Copy and export (~2 hours)

• One-click copy of the CSS code
• Export as a CSS class, Tailwind config, or Sass mixin
• Export as a PNG or SVG image
• Generate a shareable URL with the gradient encoded in the hash

Step 7: Background patterns (~3-4 hours)

• Combine gradients to create patterns (stripes, checkerboards, dots)
• Layer multiple gradients with transparency
• Show the combined CSS (multiple background layers)

Step 8: Animation (~2-3 hours)

• Animate gradient transitions (shifting colors or rotating angles)
• Generate CSS @keyframes for the animation
• Preview the animation in the browser

Step 9: Deploy (~1 hour)

• Deploy as a static site
• Add CI/CD
