CSS Gradients

➢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)

CSS Linear Gradients

➢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.

Direction - Top to Bottom (this is default)

EXAMPLE:

#grad {
     background-image: linear-gradient(green, lightgreen);
     height: 200px;
     background-color: red;
}

RESULT:

Linear Gradient - Top to Bottom

Run

Direction - Left to Right

EXAMPLE:

#grad {
     background-image: linear-gradient(to right, green, lightgreen);
     height: 200px;
     background-color: red;
}

RESULT:

Linear Gradient - Top to Bottom

Run

Direction - Diagonal

EXAMPLE:

#grad {
     background-image: linear-gradient(to bottom right, green, lightgreen);
     height: 200px;
     background-color: red;
}

RESULT:

Linear Gradient - Top to Bottom

Run

Using Angles

➢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:

0deg

90deg

180deg

-90deg

Using Multiple Color Stops

EXAMPLE:

#grad {
     background-image: linear-gradient(0deg, green, lightgreen, orange, red);
     height: 100px;
     background-color: green;
}

RESULT:

Multiple colors

Run

Using Transparency

➢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:

Run

CSS Radial Gradients

➢A radial gradient is defined by its center.
➢To create a radial gradient you must also define at least two color stops.

Radial Gradient - Evenly Spaced Color Stops (this is default)

EXAMPLE:

#grad {
background-image: radial-gradient(black, red, yellow, green);
height: 200px;
}

RESULT:

Run

Radial Gradient - Differently Spaced Color Stops

EXAMPLE:

#grad {
background-image: radial-gradient(black 10%, red 20%, yellow 30%, green 40%);
height: 200px;
}

RESULT:

Run

Conic Gradient

➢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;
}

Run

Create Pie Charts

EXAMPLE:

#grad {
     background-image: conic-gradient(black, red, yellow, green);
     height: 200px;
     border-radius: 50%;
}

RESULT:

Run

Conic Gradient With Specified From Angles

EXAMPLE:

#grad {
background-image: conic-gradient(from 90deg, black, red, yellow, green);
height: 200px;
}

RESULT:

Run

Conic Gradient With Specified Center Position

EXAMPLE:

#grad {
background-image: conic-gradient(at 60% 45%g, black, red, yellow, green);
height: 200px;
}

RESULT:
