Introduction

CSS linear gradients allow you to create smooth transitions between two or more colors. They’re essential for modern web design, from subtle backgrounds to eye-catching hero sections.

Basic Syntax

Simple Two-Color Gradient

.gradient {
  background: linear-gradient(to right, #ff6b6b, #4ecdc4);
}

Direction: to right (can be to left, to top, to bottom, or angles)

With Angle

.gradient {
  background: linear-gradient(45deg, #ff6b6b, #4ecdc4);
}

Angles:

  • 0deg = to top
  • 90deg = to right
  • 180deg = to bottom
  • 270deg = to left
  • 45deg = diagonal top-right

Color Stops

Multiple Colors

.rainbow {
  background: linear-gradient(
    to right,
    red,
    orange,
    yellow,
    green,
    blue,
    indigo,
    violet
  );
}

Positioned Color Stops

Control where colors transition:

.gradient {
  background: linear-gradient(to right, #ff6b6b 0%, #4ecdc4 50%, #45b7d1 100%);
}

Even distribution:

.gradient {
  background: linear-gradient(
    to right,
    red 0%,
    red 33%,
    blue 33%,
    blue 66%,
    green 66%,
    green 100%
  );
}

Hard Stops

Create sharp transitions:

.stripes {
  background: linear-gradient(to right, red 0%, red 50%, blue 50%, blue 100%);
}

Common Patterns

Vertical Gradient

.hero {
  background: linear-gradient(to bottom, #667eea 0%, #764ba2 100%);
}

Horizontal Gradient

.header {
  background: linear-gradient(to right, #f093fb 0%, #f5576c 100%);
}

Diagonal Gradient

.banner {
  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
}

Radial-like with Linear

.sunset {
  background: linear-gradient(to bottom, #ffecd2 0%, #fcb69f 100%);
}

Advanced Techniques

Repeating Gradients

.stripes {
  background: repeating-linear-gradient(
    45deg,
    #ff6b6b,
    #ff6b6b 10px,
    #4ecdc4 10px,
    #4ecdc4 20px
  );
}

Multiple Gradients

Layer gradients for complex effects:

.complex {
  background: linear-gradient(
      to right,
      rgba(255, 0, 0, 0.3),
      rgba(0, 0, 255, 0.3)
    ), linear-gradient(to bottom, rgba(0, 255, 0, 0.3), rgba(255, 255, 0, 0.3));
}

Gradient Over Images

.hero-image {
  background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)),
    url("hero.jpg");
}

Text Gradient

.gradient-text {
  background: linear-gradient(45deg, #ff6b6b, #4ecdc4);
  -webkit-background-clip: text;
  -webkit-text-fill-color: transparent;
  background-clip: text;
}

Color Theory for Gradients

Analogous Colors

Colors next to each other on color wheel:

.analogous {
  background: linear-gradient(
    to right,
    #ff6b6b,
    /* Red */ #ff8e53,
    /* Orange-red */ #ffa726 /* Orange */
  );
}

Complementary Colors

Opposite colors for high contrast:

.complementary {
  background: linear-gradient(to right, #ff6b6b, /* Red */ #4ecdc4 /* Teal */);
}

Triadic Colors

Three evenly spaced colors:

.triadic {
  background: linear-gradient(
    to right,
    #ff6b6b,
    /* Red */ #4ecdc4,
    /* Teal */ #ffe66d /* Yellow */
  );
}

Real-World Examples

Hero Section

.hero {
  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
  min-height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
}

Card Hover Effect

.card {
  background: linear-gradient(to bottom, #ffffff, #f5f5f5);
  transition: background 0.3s;
}

.card:hover {
  background: linear-gradient(to bottom, #667eea, #764ba2);
  color: white;
}

Button Gradient

.btn-gradient {
  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
  border: none;
  color: white;
  padding: 12px 24px;
  border-radius: 8px;
}

.btn-gradient:hover {
  background: linear-gradient(135deg, #764ba2 0%, #667eea 100%);
}

Loading Bar

.loading-bar {
  background: linear-gradient(to right, #4facfe 0%, #00f2fe 100%);
  height: 4px;
  animation: loading 2s infinite;
}

@keyframes loading {
  0% {
    width: 0%;
  }
  100% {
    width: 100%;
  }
}

Best Practices

✅ Do This

  1. Use semantic color names

    /* Good */
background: linear-gradient(to right, var(--primary), var(--secondary));

  2. Keep gradients subtle

    /* Good - subtle */
background: linear-gradient(to bottom, #ffffff, #f8f9fa);

  3. Consider performance

    • Gradients are GPU-accelerated
    • Better than images for simple effects
    • Use for backgrounds, not large areas

  4. Test contrast

    • Ensure text is readable
    • Use gradient overlays for text contrast

❌ Don’t Do This

  1. Don’t overuse

    • Too many gradients = busy design
    • Use sparingly for impact

  2. Don’t ignore accessibility

    • Check color contrast
    • Provide fallback colors

  3. Don’t use for critical UI

    • Buttons, links should have solid colors
    • Gradients can make states unclear

Browser Support

Linear gradients are well-supported:

  • ✅ Chrome 10+
  • ✅ Firefox 3.6+
  • ✅ Safari 5.1+
  • ✅ Edge 12+
  • ✅ All modern browsers

Fallbacks

.button {
  /* Fallback */
  background: #667eea;

  /* Gradient */
  background: linear-gradient(135deg, #667eea, #764ba2);
}
