CSS3 Gradients
Two types of gradients:
- Linear Gradients (goes down/up/left/right/diagonally)
- Radial Gradients (defined by their center)
Linear Gradients
syntax
background: linear-gradient(direction, color-stop1, color-stop2, ...);
1> Top to Bottom (this is default)
Example
#grad {
background: red; /* For browsers that do not support gradients */
background: -webkit-linear-gradient(red, yellow); /* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(red, yellow); /* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(red, yellow); /* For Firefox 3.6 to 15 */
background: linear-gradient(red, yellow); /* Standard syntax (must be last) */
}
2> Left to Right
Example
#grad {
background: red; /* For browsers that do not support gradients */
background: -webkit-linear-gradient(left, red , yellow); /* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(right, red, yellow); /* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(right, red, yellow); /* For Firefox 3.6 to 15 */
background: linear-gradient(to right, red , yellow); /* Standard syntax (must be last) */
}
3> Diagonal
Example
#grad {
background: red; /* For browsers that do not support gradients */
background: -webkit-linear-gradient(left top, red, yellow); /* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(bottom right, red, yellow); /* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(bottom right, red, yellow); /* For Firefox 3.6 to 15 */
background: linear-gradient(to bottom right, red, yellow); /* Standard syntax */
}
4> Using Angles
background: linear-gradient(angle, color-stop1, color-stop2);
Example
#grad {
background: red; /* For browsers that do not support gradients */
background: -webkit-linear-gradient(-90deg, red, yellow); /* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(-90deg, red, yellow); /* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(-90deg, red, yellow); /* For Firefox 3.6 to 15 */
background: linear-gradient(-90deg, red, yellow); /* Standard syntax */
}
5> Using Multiple Color Stops
Example
#grad {
background: red; /* For browsers that do not support gradients */
background: -webkit-linear-gradient(red, yellow, green); /* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(red, yellow, green); /* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(red, yellow, green); /* For Firefox 3.6 to 15 */
background: linear-gradient(red, yellow, green); /* Standard syntax */
}
6> Using Transparency
Example
#grad {
background: red; /* For browsers that do not support gradients */
background: -webkit-linear-gradient(left,rgba(255,0,0,0),rgba(255,0,0,1)); /*Safari 5.1-6*/
background: -o-linear-gradient(right,rgba(255,0,0,0),rgba(255,0,0,1)); /*Opera 11.1-12*/
background: -moz-linear-gradient(right,rgba(255,0,0,0),rgba(255,0,0,1)); /*Fx 3.6-15*/
background: linear-gradient(to right, rgba(255,0,0,0), rgba(255,0,0,1)); /*Standard*/
}
7> Repeating a linear-gradient
Example1
#grad {
background: red; /* For browsers that do not support gradients */
/* Safari 5.1 to 6.0 */
background: -webkit-repeating-linear-gradient(red, yellow 10%, green 20%);
/* Opera 11.1 to 12.0 */
background: -o-repeating-linear-gradient(red, yellow 10%, green 20%);
/* Firefox 3.6 to 15 */
background: -moz-repeating-linear-gradient(red, yellow 10%, green 20%);
/* Standard syntax */
background: repeating-linear-gradient(red, yellow 10%, green 20%);
}
Example2
#grad {
background: repeating-linear-gradient(red, blue 20px, red 40px);
background: -webkit-repeating-linear-gradient(red, blue 20px, red 40px);
background: -moz-repeating-linear-gradient(red, blue 20px, red 40px);
}
Radial Gradients
syntax
background: radial-gradient(shape size at position, start-color, ..., last-color);
1> Evenly Spaced Color Stops (this is default)
Example
#grad {
background: red; /* For browsers that do not support gradients */
background: -webkit-radial-gradient(red, yellow, green); /* Safari 5.1 to 6.0 */
background: -o-radial-gradient(red, yellow, green); /* For Opera 11.6 to 12.0 */
background: -moz-radial-gradient(red, yellow, green); /* For Firefox 3.6 to 15 */
background: radial-gradient(red, yellow, green); /* Standard syntax */
}
2> Differently Spaced Color Stops
#grad {
background: red; /* For browsers that do not support gradients */
background: -webkit-radial-gradient(red 5%, yellow 15%, green 60%); /* Safari 5.1-6.0 */
background: -o-radial-gradient(red 5%, yellow 15%, green 60%); /* For Opera 11.6-12.0 */
background: -moz-radial-gradient(red 5%, yellow 15%, green 60%); /* For Firefox 3.6-15 */
background: radial-gradient(red 5%, yellow 15%, green 60%); /* Standard syntax */
}
3> Set Shape
- ellipse（default value）
- circle
Example
#grad {
background: red; /* For browsers that do not support gradients */
background: -webkit-radial-gradient(circle, red, yellow, green); /* Safari */
background: -o-radial-gradient(circle, red, yellow, green); /* Opera 11.6 to 12.0 */
background: -moz-radial-gradient(circle, red, yellow, green); /* Firefox 3.6 to 15 */
background: radial-gradient(circle, red, yellow, green); /* Standard syntax */
}
4> Use of Different Size Keywords
- closest-side
- farthest-side
- closest-corner
- farthest-corner
Example
#grad1 {
background: red; /* For browsers that do not support gradients */
/* Safari 5.1 to 6.0 */
background: -webkit-radial-gradient(60% 55%, closest-side, red, yellow, black);
/* For Opera 11.6 to 12.0 */
background: -o-radial-gradient(60% 55%, closest-side, red, yellow, black);
/* For Firefox 3.6 to 15 */
background: -moz-radial-gradient(60% 55%, closest-side, red, yellow, black);
/* Standard syntax */
background: radial-gradient(closest-side at 60% 55%, red, yellow, black);
}
#grad2 {
/* Safari 5.1 to 6.0 */
background: -webkit-radial-gradient(60% 55%, farthest-side, red, yellow, black);
/* Opera 11.6 to 12.0 */
background: -o-radial-gradient(60% 55%, farthest-side, red, yellow, black);
/* For Firefox 3.6 to 15 */
background: -moz-radial-gradient(60% 55%, farthest-side, red, yellow, black);
/* Standard syntax */
background: radial-gradient(farthest-side at 60px 55px, red, yellow, black);
}
5> Repeating a radial-gradient
Example
#grad {
background: red; /* For browsers that do not support gradients */
/* For Safari 5.1 to 6.0 */
background: -webkit-repeating-radial-gradient(red, yellow 10%, green 15%);
/* For Opera 11.6 to 12.0 */
background: -o-repeating-radial-gradient(red, yellow 10%, green 15%);
/* For Firefox 3.6 to 15 */
background: -moz-repeating-radial-gradient(red, yellow 10%, green 15%);
/* Standard syntax */
background: repeating-radial-gradient(red, yellow 10%, green 15%);
