➢CSS gradients let you display smooth transitions between two or more specified colors.
CSS defines three types of gradients:
➢Linear Gradients (goes down/up/left/right/diagonally)
➢Radial Gradients (defined by their center)
➢Conic Gradients (rotated around a center point)
➢To create a linear gradient you must define at least two color stops. Color stops are the colors you want to render smooth transitions among. You can also set a starting point and a direction (or an angle) along with the gradient effect.
EXAMPLE:
#grad {
background-image: linear-gradient(green, lightgreen);
height: 200px;
background-color: red;
}
RESULT:
Linear Gradient - Top to Bottom
EXAMPLE:
#grad {
background-image: linear-gradient(to right, green, lightgreen);
height: 200px;
background-color: red;
}
RESULT:
Linear Gradient - Top to Bottom
EXAMPLE:
#grad {
background-image: linear-gradient(to bottom right, green, lightgreen);
height: 200px;
background-color: red;
}
RESULT:
Linear Gradient - Top to Bottom
➢If you want more control over the direction of the gradient, you can define an angle, instead of the predefined directions (to bottom, to top, to right, to left, to bottom right, etc.). A value of 0deg is equivalent to "to top". A value of 90deg is equivalent to "to right". A value of 180deg is equivalent to "to bottom".
EXAMPLE:
#grad {
background-image: linear-gradient(0deg, green, lightgreen);
height: 100px;
background-color: green;
}
#grad {
background-image: linear-gradient(90deg, green, lightgreen);
height: 100px;
background-color: green;
}
#grad {
background-image: linear-gradient(180deg, green, lightgreen);
height: 100px;
background-color: green;
}
#grad {
background-image: linear-gradient(-90deg, green, lightgreen);
height: 100px;
background-color: green;
}
RESULT:
➢If you want more control over the direction of the gradient, you can define an angle, instead of the predefined directions (to bottom, to top, to right, to left, to bottom right, etc.). A value of 0deg is equivalent to "to top". A value of 90deg is equivalent to "to right". A value of 180deg is equivalent to "to bottom".
EXAMPLE:
#grad {
background-image: linear-gradient(0deg, green, lightgreen, orange, red);
height: 100px;
background-color: green;
}
RESULT:
➢CSS gradients also support transparency, which can be used to create fading effects.
➢To add transparency, we use the rgba() function to define the color stops. The last parameter in the rgba() function can be a value from 0 to 1, and it defines the transparency of the color: 0 indicates full transparency, 1 indicates full color (no transparency).
EXAMPLE:
#grad {
background-image: linear-gradient(to right, rgba(255,0,0,0), green);
height: 200px;
}
RESULT:
➢A radial gradient is defined by its center.
➢To create a radial gradient you must also define at least two color stops.
EXAMPLE:
#grad {
background-image: radial-gradient(black, red, yellow, green);
height: 200px;
}
RESULT:
EXAMPLE:
#grad {
background-image: radial-gradient(black 10%, red 20%, yellow 30%, green 40%);
height: 200px;
}
RESULT:
➢A conic gradient is a gradient with color transitions rotated around a center point.
➢To create a conic gradient you must define at least two colors.
EXAMPLE:
#grad {
background-image: conic-gradient(black, red, yellow, green);
height: 200px;
}
RESULT:
EXAMPLE:
#grad {
background-image: conic-gradient(black, red, yellow, green);
height: 200px;
border-radius: 50%;
}
RESULT:
EXAMPLE:
#grad {
background-image: conic-gradient(from 90deg, black, red, yellow, green);
height: 200px;
}
RESULT:
EXAMPLE:
#grad {
background-image: conic-gradient(at 60% 45%g, black, red, yellow, green);
height: 200px;
}
RESULT:
